Cylindrical Roller Bearing

Description

Cylindrical roller bearings have no ribs on either the inner or outer ring, so therings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, single and double row full complement bearings (without a cage) complete the international standard assortment listed.

Features

1.) Offers a complete range, both metric and inch sizes available in metric and

imperial bore sizes ranging from 12 to 1320 mm.

2.)High radial load capacity - making cylindrical roller bearings suitable for high

speed applications.

3.)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.

4.) Cages - Available with pressed steel, machined brass and polyamide cages

throughout the range. 

5.) Special designs - manufactures a range of four-row cylindrical roller bearings,

primarily designed for use as steel mill roll-neck bearings.

6.)Bearings are also available with both lubrication holes and a machined

lubrication groove on the outside surface of the outer ring.

Application of cylindrical roller bearings:

Cylindrical roller bearings are used in a variety of applications. Examples include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. Some cylindrical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools and traction motors and pumps.
