SS 410 420 Connector Hardware Adjusting Bearing Connectors M4 Mounting Screws Bolts

Stainless steel adjusting bearing screws, bearing connectors M4 precision bolts

We specialize in the manufacturing of slotted bearing screws and slotted adjustment screws featuring high precision that achieve tight fit with bearings, enabling stable and smooth operation.

We can produce bearing connectors in various materials according to customer requirements.

• Ultra-high fitting precision: Precision forming technology ensures high thread accuracy and good concentricity for zero-clearance tight fit with bearing inner rings and shaft systems, ensuring smooth rotation, no noise, and no jamming during long-term operation.
• Precise slotted adjustment: Slotted design provides uniform force and clear adjustment feel, supporting micro angle and axial clearance fine-tuning. Ideal for precision equipment calibration, tension adjustment, and positioning locking with easy assembly, disassembly and maintenance.
• Various materials & customizable: Available in carbon steel, high-strength alloy steel, 304/316 stainless steel, copper alloy, titanium alloy, etc. Surface treatments include zinc plating, nickel plating, blackening, Dacromet, etc., providing rust resistance, wear resistance and corrosion resistance for various environments.
• Stable structure & high durability: High torque, fatigue resistance and excellent anti-loosening performance. Maintains locking force under continuous vibration and high-speed rotation, reducing downtime and extending equipment service life.

• Automation equipment & robots: Fastening and fine-tuning for joint bearings, rotating shaft systems, servo transmission
• Precision machine tools & molds: Positioning and locking for spindle assemblies, linear guides, slider bearings
• Electronics & home appliances: Precision fixing for motor bearings, fan shafts, transmission components
• Automotive & new energy equipment: Seat adjustment mechanisms, sunroof guides, transmission bearing connections
• Optical, medical & instrumentation: Micro bearing matching for high-precision rotation and adjustment mechanisms
• General machinery & transmission systems: Bearing housing locking and clearance compensation for conveyors, textile, packaging equipment
