Cylindrical roller bearings are commonly separable and easy to mount and dismount. They can be divided into single row, double row and muti-row cylindrical roller bearings. The widely used bearings are cylindrical roller bearings with cage. There are single or double row bearings with a full complement of roller and other bearing arrangements. Cylindrical roller bearings have high radial load carrying capacity and are also suitable for high speeds.

Product Features and Benefits:
· We offers a complete range, both metric and inch sizes available in metric and imperial bore sizes ranging from ½ " to 1320 mm.
· High radial load capacity - making them suitable for high speed applications.
· Designs - designated NU, NJ, NUP, N or NF for single row bearings and NNU or NN for double row types, defines the bearing ring rib configuration.
· Cages - Available with pressed steel, machined brass and polyamide cages throughout the range.
· Special designs - We manufactures a range of four-row cylindrical roller bearings, primarily designed for use as steel mill roll-neck bearings.
· Bearings are also available with both lubrication holes and a machined lubrication groove on the outside surface of the outer ring.
