Function of each surface
The locating surface, guiding section, shoulder and fastening thread are distinguished so their tolerances serve the intended function.

Shaft Collar
- Bore and tolerance
- Outside diameter and width
- Split or fastening arrangement
- Material and surface requirement
Do not assume a collar style from the bore diameter. State the approved configuration.
Special Screw
- Thread specification
- Head and shank geometry
- Material and treatment
- Drawing revision and quantity
A commercial screw name cannot replace non-standard dimensions or treatment requirements.
Custom Locking Part
- Drawing and revision
- Mating interface dimensions
- Material and finish
- Critical acceptance features
Locking part covers many different designs. Provide the actual part drawing before feasibility review.
Fixture Bushings
- Bore and tolerance
- Outside diameter and fit
- Length and flange geometry
- Material and hardness requirements
Nominal inside and outside diameters do not define locating fits. Include tolerances and the approved installation requirement.
Indexing Plungers
- Exact model or drawing
- Mounting thread and body length
- Pin diameter and travel
- Operating and locking arrangement
A thread size alone does not define the pin or operating arrangement. Preserve the full reference and option code.
Hinge & Cantilever Pins
- Diameters and tolerances
- Lengths and shoulders
- Retention thread or groove
- Material and treatment
A total length does not define shoulder positions or retention geometry. Include a drawing with datum references.
Retaining Rings
- Standard or full reference
- Shaft or bore application
- Groove reference
- Material and finish
A nominal shaft size does not specify every ring or groove requirement. Use the approved reference and mating drawing.
Stopper Bolts
- Thread and mounting length
- Contact-end geometry
- Adjustment and overall length
- Material and treatment requirements
A screw thread does not identify the contact geometry or adjustment arrangement. Include the equipment requirement or drawing.
Supply routes
Distributed BrandsSupply by specified model, China-made production or drawing.
For brand distribution, China-made components and drawing-based parts, origin, specifications and supply terms are confirmed by item.
PRODUCT FORMS
A clear view of the available forms.
Locating parts establish position; fastening parts hold the assembly. Their fit, contact surfaces and material condition are linked to the drawing and mating component.
| Product form | Construction | Selection focus | Connected components |
|---|---|---|---|
| Locating pins | Cylindrical or shaped locating head with a mounting shank | Locating datum, head geometry and fit direction | Mating bushings and fixture plates |
| Locating bushings | Sleeve provides the mating locating surface | Inside fit, outside retention and replacement method | Locating pins and receiving holes |
| Shoulder screws | Defined shoulder and threaded fastening section | Shoulder length, bearing surface and thread engagement | Guided, pivoting or spaced components as drawn |
| Locking and special fasteners | Threaded or clamping geometry follows the connection | Contact geometry, tool access and retention method | Shafts, bearings, pulleys and drawing-based spacers |
INTERFACE & SELECTION
The details that connect the assembly.
Mating-part relationship
A pin and bushing are considered with their mounting holes and assembly direction, including planned replacement and disassembly.
Material and finishing sequence
Material, heat treatment and surface finish are kept with the drawing revision because these can affect final dimensions and fit.
INTEGRATED SUPPLY
Connected parts in one component list.
Guide installation
Locating and fixing elements connect the rail and carriage arrangement to the machine reference surfaces.
Linear GuidesPulley assembly
Spacers and locking parts complete the pulley-to-shaft connection around the approved drawing.
Timing Pulleys & BeltsBearing retention
Collars, locknuts and related parts are matched to the bearing arrangement and shaft interfaces.
BearingsRFQ information
A complete model is enough to begin. Partial information is welcome too.
A model, photo, drawing or BOM can start the discussion; brand, quantity and critical interfaces can be clarified by item.
