Key Design Features
- Crowned Outer Ring: Reduces edge stress and compensates for minor misalignment, ensuring stable operation in cam drives and linear systems.
- Full-Complement Needle Rollers: Maximizes load-bearing capacity in a compact envelope, delivering 3–4 times higher radial load capability than standard ball bearings of similar size.
- Shielded Protection: Prevents dust, metal chips, and coolant from entering the bearing, extending service life in harsh industrial environments.
- Threaded Stud with Hex Head: Enables quick, tool-free installation via a hex socket, ideal for automated assembly and maintenance.
- High-Rigidity Structure: Thick-walled outer ring and integrated stud design minimize deflection under heavy loads, supporting precision motion control.
- Wide Temperature Tolerance: Operates reliably from -20°C to +120°C, suitable for high-temperature and cold-chain applications.
- Relubricatable: Equipped with lubrication holes for easy relubrication, extending service life in continuous-operation systems.
Typical Applications
- Cam mechanisms and drive systems for machine tools
- Industrial robot arms and automated handling equipment
- Conveyor systems and linear motion slides
- Packaging machinery and printing presses
- Medical device actuators and precision positioning systems
- Automotive assembly line fixtures and jigs
