61900-2Z/LHT23 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 10mm (bore) x 22mm (OD) x 6mm (width) and a weight of just 0.01 kg, this bearing is engineered for applications with severe space and weight constraints.
- Shielded for Protection: The 2Z shields provide effective protection against particulate contamination while minimizing friction, contributing to the high limiting speed of 45,000 rpm.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to handle significant radial loads (Dynamic: 607 lbf, Static: 286 lbf), ensuring stable operation.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class with CN radial internal clearance, this bearing offers reliable running accuracy and low vibration for smooth performance.
- Wide Temperature Range: Constructed entirely from chrome steel, the bearing operates reliably within a temperature range of -30°C to 120°C.
