UJK Clutch Release Bearings

UJK Clutch Release Bearings: Precision Engagement for Automotive & Heavy-Duty Agriculture

UJK clutch bearings deliver reliable torque transfer and smooth disengagement in high-stress drivetrain systems. Engineered for extreme axial loads, thermal cycling, and contamination-prone environments, they ensure extended service life in passenger vehicles, commercial trucks, and agricultural machinery.

I. Automotive Clutch Bearings

Design Focus: High-speed precision, low pedal effort, NVH reduction.

Series Type Bore (mm) Max. Axial Load (kN) RPM Limit Sealing Applications
CSC-200 Concentric Slave Cylinder 22-45 12-18 8,000 Triple-lip + Dust Shield Passenger Cars (FWD/RWD)
RB-70 Conventional Release Bearing 30-55 10-15 6,500 PTFE-Sealed + Spring Cage Trucks, Light Commercial
HSC-300 Hydraulic Slip Control 18-35 8-12 10,000 Laser-Welded Bellows Performance/Sports Vehicles
Core Automotive Technologies:
  • Low-Friction Polymer Liners: Reduce pedal effort by 25% vs. standard bearings.
  • Integrated Hydraulics: Eliminate external slave cylinders for compact packaging.
  • Thermal-Resistant Grease: Stable at -40°C to +220°C (DIN 51825 K2K-40).
  • Anti-Squeal Coatings: MoS-treated sliding surfaces prevent NVH.
II. Agricultural Clutch Bearings

Design Focus: Contaminant exclusion, shock load resistance, corrosion protection.

Series Type Bore (mm) Max. Axial Load (kN) IP Rating Reinforcement Compatible Machinery
AG-RS1 Heavy-Duty Release 40-80 25-40 IP6K9K Forged Steel Cage + Wipers Tractors (>150 HP)

Frequently Asked Questions
What materials are used in UJK clutch bearings?
We use high-grade Chrome Steel Gcr15 for the bearing components, with cages available in Steel, Nylon, or Brass depending on the application requirements.
Can these bearings withstand extreme temperature environments?
Yes, our bearings use thermal-resistant grease that remains stable from -40°C to +220°C, and certain series feature hybrid liners that sustain up to 250°C.
Are UJK bearings suitable for heavy-duty agricultural machinery?
Absolutely. Our AG-RS1 and PTO-X series are specifically designed for tractors and harvesters, featuring IP6K9K ratings for protection against mud, dust, and high-pressure washing.
What is the precision rating of your clutch bearings?
We manufacture bearings to P0, P6, and P5 precision standards to ensure vibration-free engagement and high-speed stability.
Do you provide OEM services for specific vehicle models?
Yes, we offer comprehensive OEM services and can customize bearing specifications, including preload and clearance optimization, for specific drivetrain requirements.
How do UJK bearings reduce pedal effort in automotive applications?
Our automotive series utilizes low-friction polymer liners and integrated hydraulics (CSC/HSC) which can reduce required pedal effort by up to 25% compared to standard bearings.
