Overview
Nachi 6940 MY Deep groove ball bearing
Deep Groove Ball Bearing, open design with machined brass cage
The Nachi 6940 MY is a very large open deep groove ball bearing with a 200 mm bore, 280 mm outside diameter and 38 mm width, built around a machined brass cage. Brass is specified in the larger sizes because it stands up to high temperature, poor lubrication and shock better than a pressed steel cage, and it damps the ball set more effectively at speed. Normal CN clearance, open on both sides for oil or grease, rated -20 to +120 degrees C.
Key features
- Machined brass cage for demanding duty
- Better tolerance of heat, shock and marginal lubrication
- Normal CN radial internal clearance
- Open design for oil or grease lubrication
- Well suited to large, heavily loaded shafts
- Operating range -20 to +120 degrees C
