Product Description

Single Row Roller Bearings NUP2300 Series have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, and these rollers are guided by ground ribs on either the inner or outer ring. The Cylindrial Roller Bearings NUP2300 Series shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.

Precision Roller Bearings NUP2300 Series

Precision Roller Bearings NUP2300 Series features
Low friction (Roller end / flange contact area)
The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
Enhanced operational reliability
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
Separable and interchangeable
The separable components of Single Row Roller Bearings NUP2300 Series are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
High speed capability
The cage designs are suitable for high speeds, rapid accelerations and peak loads.
