Professional Production of Slotted Bearing Screws & Slotted Adjustment Screws
We specialize in the manufacturing of slotted bearing screws and slotted adjustment screws.
Our screws feature high precision and achieve a tight fit with bearings, enabling stable and smooth operation.
We can produce bearing connectors in various materials according to customer requirements.
Core Product Features
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.
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.
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.
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.
Typical Application Scenarios
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
We support customization based on drawings or samples.
According to customer bearing models, assembly space, load and environmental requirements,
we develop dedicated slotted bearing screws and connectors,
providing stable and reliable precision fastening solutions for high-end equipment.
