Fits when
- The machine requires a cylinder with a confirmed holding/locking function
- The installed label or drawing identifies BSAI or BSAID

Avoid a wrong match
- Locking function is a safety-relevant mechanical distinction; do not infer it from bore and stroke
- BSAI and BSAID have different rod arrangements
- S denotes the magnetic option, not a separate product family
Choose the BSAI family first
A similar body does not guarantee the same function. Confirm the function and interface first, then compare size and installed dimensions.
Read the model code
If the label is incomplete, send the readable parts together with a photo.

About BSAI
BSAI is a locking-cylinder family for applications where the cylinder must be held in position. Its lock direction and release method must be confirmed; a standard cylinder with the same bore and stroke is not an automatic substitute.
Product matching reference
Compare the photo, drawing, and measurable details first
Identify from the photo
- Full BSAI or BSAID model code or readable label
- Bore and stroke
- Lock direction and pneumatic/manual release arrangement
- Single-rod or double-rod construction, mounting, port and installed clearance
Drawing reference
- Confirm the lock direction and release method before matching
- Compare bore, stroke, mounting, port, rod-end, and installed clearance
- Use the matching BSAI or BSAID drawing for the installed configuration

Matching Questions
What should be confirmed before sourcing a BSAI cylinder?
Confirm the full BSAI or BSAID code, bore, stroke, lock direction, release method, rod arrangement, mounting and ports. Send a label or drawing...
Can a standard ISO cylinder replace a BSAI locking cylinder?
Not automatically. The holding/locking function, release method and installed interfaces need separate confirmation before any replacement decision.
