Overview
Nachi 6004 ZZECM Deep groove ball bearing
Deep Groove Ball Bearing with shields on both sides and restricted CM clearance
This Nachi 6004 ZZECM is a small shielded deep groove ball bearing of 20 mm bore, 42 mm outside diameter and 12 mm width, supplied to the CM clearance range. CM narrows the tolerance band rather than shifting it, delivering the consistent, repeatable running clearance that fractional and integral electric motors need for low noise and predictable bearing life. Steel shields on both sides retain the grease charge, a pressed sheet steel cage guides the balls, and the working range is -40 to +120 degrees C.
Key features
- Restricted CM clearance range for electric motors
- Steel shields both sides, greased for life
- Consistent running clearance, low noise
- Pressed sheet steel cage
- No relubrication required
- Operating range -40 to +120 degrees C
