21
+| | | Sprocket / Pulley | Sprocket, timing pulley | Used with chain/belt transmission |
22
+| | | Coupling | Flexible coupling, diaphragm coupling | Connect two shafts, transmit torque |
23
+| | | Universal Joint / Cross Shaft | Universal joint, cross shaft | Change rotation direction |
24
+| **Support & Positioning Parts** | Support rotational or linear motion | Bearing | Ball bearing, roller bearing, plain bearing | Support rotating shaft, reduce friction |
25
+| | | Slider / Rail | Slide rail, linear slider | Support linear motion, precise guidance |
26
+| | | Pin / Pin Shaft | Cylindrical pin, tapered pin | Positioning, support rotating or sliding parts |
27
+| | | Bolt / Nut | Hex bolt, flange nut | Fasten parts |
28
+| | | Washer / Spring Washer | Flat washer, spring washer | Adjust gap, prevent loosening |
29
+| **Buffer / Damping Parts** | Control motion or absorb impact | Buffer Block | Rubber buffer, polyurethane buffer | Absorb impact, limit travel |
30
+| | | Damper | Pneumatic damper, hydraulic damper, rotary damper | Control motion speed, slow movement |
31
+| | | Spring | Compression spring, tension spring, torsion spring | Provide force, reset, or absorb energy |
32
+| **Connecting Parts** | Fix or transmit torque | Key / Keyway | Flat key, half-round key, wedge key | Fix wheel to shaft, transmit torque |
33
+| | | Spline / Internal-External Spline Sleeve | Spline shaft, spline sleeve | High torque transmission |
34
+| | | Chain / Belt | Roller chain, timing belt | Transmit mechanical motion |
35
+| **Auxiliary Parts** | Assist positioning or movement | Roller / Ball Guide | Ball pulley, roller bearing | Reduce friction, guide sliding |
36
+| | | Adjustment Screw | Ejector screw, fine adjustment screw | Fine-tune position or tension |
37
+| | | Locking Device | Set screw, circlip, retaining ring | Fix rotating or moving parts |
