| 2Z | Double-sided steel shields | Effective contamination protection while maintaining low torque |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
E2.627-2Z/C3 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The single row deep groove raceway geometry enables excellent radial load capacity (776 lbf dynamic / 308 lbf static) while accommodating moderate axial loads in both directions.
Enhanced Protection System: Double-sided steel shields (2Z) provide superior protection against dust and particulate contamination without significantly increasing rotational torque, making them suitable for applications where sealed bearings cannot be used.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional control (bore: -0.007mm to 0, OD: -0.008mm to 0) ensures consistent performance and easy installation.
Thermal Compensation: The C3 radial clearance accommodates differential thermal expansion between shaft and housing, preventing premature failure in applications with temperature variations up to 120°C.
High-Speed Capability: With a limiting speed of 36,000 rpm, this bearing delivers reliable performance in high-speed applications while maintaining operational stability.
