NSK 23028CDKE4C3S11 Spherical Roller Bearing

Description

The NSK 23028CDKE4C3S11 is a high-quality spherical roller bearing engineered for superior performance in demanding industrial environments. This bearing features two rows of symmetrical rollers, a common sphered outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis. Its design allows it to accommodate misalignment and heavy radial and axial loads in both directions.

FAQ

The C3 clearance indicates that the internal radial clearance of the bearing is greater than the 'Normal' (CN) clearance. This is crucial for applications where there are significant temperature differences between the inner and outer rings, or where a tight interference fit is required, as it prevents the bearing from seizing due to thermal expansion.

The 'K' suffix denotes a tapered bore, specifically with a 1:12 taper. This design allows for mounting on a tapered shaft journal or, more commonly, on a cylindrical shaft using an adapter sleeve (H series) or a withdrawal sleeve (AH series). This mounting method provides a secure fit and simplifies both installation and dismounting.

This bearing is typically shipped with a preservative oil or rust inhibitor, not a full operational grease fill. It must be cleaned and lubricated with the appropriate grease or oil according to the specific application's speed, load, and temperature requirements before being put into service.
