Single Row Cylindrical Roller Bearings

With line contact between rollers and raceways, these bearings deliver superior load distribution and are available in multiple designs such as NU, NJ, NUP, N, NF, and NH, depending on flange configuration. They are widely used in heavy-duty machinery requiring precision and durability.

Types & Features of Single Row Cylindrical Roller Bearings

NU Type

• Outer ring with flanges on both sides; inner ring without flange

• Easy mounting with separable components

NJ Type

• Inner ring with flanges on both sides; outer ring without flange
• Handles radial loads only
• Used as floating bearing
• Inner assembly includes rollers and cage

N Type

• Outer ring with two flanges; inner ring with one flange
• Supports radial load and axial load in one direction
• Suitable for fixed or floating applications

NF Type

• Inner ring with two flanges; outer ring with one flange
• Handles radial load and axial load in one direction
• Can be used as fixed or floating bearing

NH Type

• Combination design with flange support and L-shaped collar
