Overview
Nachi 2309 GK Self-aligning ball bearing
Self-Aligning Ball Bearing with polyamide cage, tapered bore and normal clearance
Nachi's 2309 GK is a wide-section double-row self-aligning ball bearing with a 45 mm bore, 100 mm outside diameter and 36 mm width, combining a 1:12 tapered bore with a glass-fibre reinforced polyamide cage. The taper takes an adapter sleeve for mounting on plain shafting; the moulded cage cuts weight and noise and copes better with shock. Normal CN starting clearance. Self-aligning on a spherical outer raceway, rated -30 to +120 degrees C.
Key features
- Tapered 1:12 bore for adapter sleeve mounting
- Glass-fibre reinforced polyamide cage
- Wide section for higher load capacity
- Normal CN clearance before mounting
- Self-aligning, quiet running
- Operating range -30 to +120 degrees C
