Product Overview
Cylindrical lock components can combine a round locating body with openings or end connections.
Their function depends on how the cylinder is retained and actuated in the lock.
Structure & Mating Interfaces
Specify the locating diameter, end features and position of any openings.
Clarify whether each opening retains, connects or simply clears another part.
Engineering Focus
Why identify the function of each cylinder opening?
An opening may guide, retain, connect or clear another component.
These roles determine which size and position relationships matter.
Defining the role makes it possible to apply controls to the working interface rather than to all openings indiscriminately.
Manufacturing Route & Finishing
Compare turning for the cylindrical base with MIM or secondary machining for integrated detail.
Final bore or outside-fit requirements should be reviewed after finishing.
The proposed route is confirmed for your drawing, material and quantity. An image does not establish a fixed tolerance or a complete process specification.
Compare manufacturing capabilities →Materials & Surface Requirements
Specify the base material, final condition and corrosion or appearance requirements.
Mark drive, guiding and contact surfaces that must meet their dimensions after treatment.
The component specification does not establish a security rating for the complete lock.
Review material-selection information →Quality & Sample Approval
Inspect locating fit, opening positions and end engagement.
Check the intended lock action with the mating body and actuator.
Specify the drawing revision and the condition in which each dimension is inspected. Record the agreed dimensional and functional checks before sample approval.
Quality documentation →Prepare a Product-Specific RFQ
- Component definition. Send the 2D drawing and 3D model, where available, with the drawing revision and the requested part or assembly scope.
- Mating information. Include the assembly references needed to define the interfaces discussed above.
- Delivered condition. State material, finishing and inspection requirements, identifying any items that need a manufacturing recommendation.
- Supply plan. Include sample needs, expected order and annual quantities, packaging requirements and target timing.
Product Questions
Can all openings use one general position tolerance?
Their controls should follow their functions and datums; retention or drive openings may need different requirements from clearance holes.

How should the completed mechanism be checked?
Inspect locating fit, opening positions and end engagement. Check the intended lock action with the mating body and actuator.
