- Enhanced Thermal Stability: The C3 internal clearance provides extra space between the rolling elements and raceways, compensating for thermal expansion in high-temperature or high-speed environments.
- Effective Contaminant Protection: High-quality 2RS rubber contact seals ensure that lubricants are retained while preventing the ingress of dust, moisture, and debris into the bearing's internal components.
- High Radial Rigidity: The back-to-back internal arrangement offers a rigid bearing configuration capable of resisting tilting moments and maintaining shaft alignment under heavy stress.
- Maintenance-Free Operation: Pre-lubricated with high-performance grease, this sealed unit is designed for a long service life without the need for frequent re-lubrication.
