Professional Production of Slotted Bearing Screws & Slotted Adjustment Screws

Core Product Features

1. Ultra-high fitting precision

    

   Adopting precision forming technology, our screws have high thread accuracy and good concentricity.

    

   They can achieve zero-clearance tight fit with bearing inner rings and shaft systems,

    

   ensuring smooth rotation, no noise, and no jamming during long-term operation.
    
2. Precise slotted adjustment

    

   The slotted design provides uniform force and clear adjustment feel,

    

   supporting micro angle and axial clearance fine-tuning.

    

   It is ideal for precision equipment calibration, tension adjustment, and positioning locking,

    

   with easy assembly, disassembly and maintenance.
    
3. 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 indoor precision equipment, outdoor, humid and harsh environments.
    
4. 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.
