Overview
Nachi 1203 C3 Self-aligning ball bearing
Self-Aligning Ball Bearing with cylindrical bore and increased clearance
Nachi's 1203 C3 is a small double-row self-aligning ball bearing of 17 mm bore, 40 mm outside diameter and 12 mm width, supplied with C3 clearance. The spherical outer raceway lets the ball set swivel to follow a deflecting shaft or a misaligned housing without loading the bearing edges, and C3 clearance adds room for thermal growth and interference fits on top of that. Very low friction and correspondingly low heat generation. Cylindrical bore, sheet steel cage, rated -30 to +150 degrees C.
Key features
- Self-aligning, tolerates misalignment and deflection
- Increased C3 clearance for thermal expansion
- Lowest friction of any rolling bearing type
- Cylindrical bore for direct shaft mounting
- Sheet steel cage
- Operating range -30 to +150 degrees C
