Product Overview
The American standard cylinder is an American profile cylinder for door hardware, locksmith supply and OEM lock assembly, built with a brass housing, brass plug and brass key. It meets EN 1303 and carries 5 active and 5 passive pins as standard, with 5-7 pins available to order. The A dimension starts at 23 mm (23-48.5 mm optional) and the L dimension at 25.5 mm (25.5-51 mm optional).
For a buyer specifying a cylinder across a lock range, the value is in the configuration rather than the base unit. Cam type, knob type, keying mode and protection options are chosen per door or per order, so one cylinder family covers several hardware lines without a second supply chain.
Key Features
- EN 1303 compliance: the cylinder can be specified into lock programs that call for a recognised European cylinder standard.
- Brass housing, plug and key: the three wear surfaces are the same material, which keeps tolerances stable through repeated key cycles.
- 5 active and 5 passive pins standard, 5-7 optional: pin count is set to the keying system you run, not fixed at one level.
- Vertical key and dimple key types: one cylinder body serves both key styles, so a mixed key program stays on one part number family.
- KA, CE, MK and GMK keying possibilities: keyed-alike, keyed-to-differ, master key and grand master key systems can be quoted from the same cylinder.
- Optional anti-drill, anti-pick and anti-bump protection: protection is added to the housing or plug only where the door schedule asks for it.
- Cam and knob options: the cam list and eight knob types let the cylinder match the lockcase and the door face rather than the other way round.

Industrial Applications
- American cylinder for door hardware: hardware distributors and door-set assemblers fit the cylinder into commercial and residential locksets; the A and L dimensions are chosen to match the lockcase backset and door thickness, and the 23-48.5 mm A and 25.5-51 mm L ranges cover the common backset and door thickness combinations without a custom part.
- American cylinder for locksmith supply: locksmiths stock the cylinder for rekeying and replacement work, using KA and MK keying to keep building master key systems consistent; the 5-7 active and 5-7 passive pin configuration lets a single stock line serve both single-door and master-keyed jobs.
- American cylinder for OEM lock assembly: lock factories specify the cylinder into their own product lines and use the cam and knob list to match existing housings without redesigning the lock; the cam and knob are selected at order stage so the cylinder drops into the existing housing without machining.
- Replacement and retrofit work: property managers and maintenance teams order the cylinder to replace worn units in existing American profile locks, matching the original cam and knob type; the A and L dimensions are checked against the existing lockcase so the replacement fits the original door preparation.
- Security upgrade projects: specifiers add anti-drill, anti-pick or anti-bump protection to the housing or plug where the door schedule calls for it, while keeping the same cylinder footprint; protection is ordered per line item, so only the doors named in the schedule carry the added features.
Key Advantages
- The cylinder is built on a brass housing, brass plug and brass key, so the three parts that wear against each other share the same material behaviour and the pin tolerances hold through service cycles.
- EN 1303 compliance means the cylinder can go into a specification that names a standard, which shortens approval on commercial door schedules.
- A pin range of 5-7 and four keying modes (KA, CE, MK, GMK) let one cylinder family cover a single door and a master keyed building without a second product line.
- Eight cam types and eight knob types mean the cylinder is matched to the lockcase and door face at order stage, which removes field modification from the installation.
- Protection options are ordered per line item, so security features are paid for only on the doors that need them.
- A and L dimensions are built to order across 23-48.5 mm and 25.5-51 mm, so the cylinder fits the lockcase backset and door thickness instead of forcing the door preparation to change.
- We produce the full range in-house, so cam, knob, pin count and keying chart are confirmed against your drawing before the order is released.
How to Choose the Right Configuration
| Standard 5-pin cylinder | suits single doors and small keyed-alike groups where a 5-pin keying system is already in use. |
|---|---|
| 5-7 pin cylinder | suits master keyed and grand master keyed buildings where the keying chart needs more combinations. |
| Vertical key cylinder | suits sites standardising on a vertical key profile for staff or tenant keys. |
| Dimple key cylinder | suits sites that want a dimple key profile and the key control that goes with it. |
| Cylinder with protection options | suits exterior doors and higher-risk openings where anti-drill, anti-pick or anti-bump protection is specified. |
| Cylinder with decoration cam | suits exposed cylinder faces where the cam housing is visible on the door. |
Why Choose Us
We quote the American standard cylinder price against the configuration you send, not against a base unit, so the cam, knob, pin count and protection are priced line by line.
Brass housing, plug and key production is held in-house, which keeps the material grade consistent between orders.
OEM and ODM work is handled at drawing level: send the cam profile, knob type and keying chart, and we return a specification for approval before production.
Spare parts and repeat orders are quoted from the original configuration record, so a second batch matches the first without re-specifying.
Mixed container loads are routine: cylinder variants can be combined with other lock components in one shipment for China-based buyers.
Factory Strength
Cylinder production runs through brass machining, pin and key cutting, assembly and inspection under one roof. Each unit is built to the ordered pin count and keying mode, then checked for key insertion, rotation and cam fit before it is packed. Export orders are consolidated at the factory and shipped to North American and European markets, where the EN 1303 cylinder specification is the reference buyers work from. Custom cams, knob types and keying charts are handled as engineering orders rather than catalogue picks.
Quality Control
Incoming brass is checked before machining, and pin, plug and housing dimensions are inspected through production. Finished cylinders are tested for key operation and cam fit, and the keying mode is verified against the order chart before packing.
- Incoming material check on brass stock
- In-process dimension checks on housing, plug and pins
- Final function test on key insertion, rotation and cam fit
- Keying verification against the order chart before packing
Packaging & Delivery
Cylinders are packed by configuration and keying mode, with the order chart enclosed so the receiving team can match keys to doors. Mixed configurations are separated and labelled before cartoning.
- Packing: individual cylinder protection, then cartons labelled by configuration
- Mixed orders: separated by cam, knob and keying mode
- Shipping: consolidated at the factory for export
- Buyer to supply: keying chart, cam and knob selection, and delivery marks
FAQ
What is the difference between the American standard cylinder and a Euro profile cylinder?
This is an American profile cylinder, built to the American cylinder shape rather than the Euro profile. It is specified with EN 1303 and uses the cam and knob list shown in the configurations section.
What do the A and L dimensions mean on the American standard cylinder specifications?
A is the cylinder length dimension and L is the overall length. Standard A is 23 mm with 23-48.5 mm optional, and standard L is 25.5 mm with 25.5-51 mm optional. Send the lockcase drawing and we will confirm which pair fits.
Can I get the American standard cylinder datasheet with the cam and knob options?
Yes. The datasheet covers the EN 1303 reference, brass housing, plug and key, pin counts, keying modes, the A and L ranges, and the full cam and knob lists. Tell us which configuration you are considering and we will send the matching sheet.
Which cam should I order for my lockcase?
The available cams are Italian cam, DIN cam for single locks, Swiss cam for single locks, 10 teeth gear cam, Iseal cam for seven pins, Swiss cam for double locks, DIN cam of cross for double locks and 14 teeth gear cam. Send the lockcase model or a photo of the existing cam and we will match it.
Can the cylinder be used for American cylinder for door hardware projects?
Yes. Hardware distributors and door-set assemblers order it with the A and L dimensions matched to the lockcase and the knob type matched to the door face. Protection options can be added on the doors that need them.
Do you support American cylinder for OEM lock assembly?
Yes. Send the cam profile, knob type, pin count and keying chart, and we will return a specification for approval before production. Custom cams and knob types are handled as engineering orders.
What is the American standard cylinder price for a mixed order?
Price depends on pin count, keying mode, cam, knob type, finish and protection options. Send the line items and quantities and we will quote each configuration separately.
What is your MOQ and lead time for a trial order?
MOQ and lead time depend on the configuration and the keying chart. Tell us the pin count, cam and knob selection and the quantity you need for a trial, and we will confirm both before you place the order.
How are the cylinders packed and shipped?
Cylinders are packed by configuration and keying mode, with the order chart enclosed so keys can be matched to doors on receipt. Mixed orders are separated and labelled before cartoning, and export shipments are consolidated at the factory.
Can I buy the American standard cylinder directly from a China supplier?
Yes. We are an American standard cylinder supplier China-based, and orders are placed directly with the factory rather than through a trading layer. Send the cam, knob, pin count and keying chart and the quotation is issued against your line items.
