627-2ZTN9/C2HLHT23 Bearing Structural Features & Performance Benefits
Optimized Bearing Geometry: The deep groove raceway design enables efficient radial load distribution, while the precision-ground chrome steel components ensure smooth operation and minimal friction losses.
Enhanced Contamination Protection: The double-sided steel shields (2Z) provide reliable protection against dust and particulate ingress, significantly extending bearing service life in challenging environments without requiring additional sealing components.
High-Speed Capability: The glass fiber reinforced nylon cage (TN9) offers excellent strength-to-weight ratio, reducing centrifugal forces and enabling stable operation at limiting speeds up to 30,000 rpm.
Precision Engineering: With ABEC 1 | ISO P0 tolerance class and C2 radial clearance, this bearing delivers consistent performance with minimal runout and vibration, making it suitable for precision applications.
Temperature Resilience: The HLHT23 grease formulation maintains optimal lubrication characteristics across a wide operating temperature range from -30°C to 120°C, ensuring reliable performance in varying environmental conditions.
