Type of Bearing	Cylindrical Roller Bearing
Bearing Number	239/530
Dimension	20 X 40 mm
Usage/Application	Industrial
Brand	EVO
Material	Mild Steel
Country of Origin	Made in India

ETC EVO Cylindrical Roller Bearing are divided into single row and double-row types. Their feature is high radial load carrying capacity because the rollers and raceway are in linear contact.
These bearings are suitable for applications that involve heavy radial impact loading. The cage of ETC EVO single-row cylindrical roller bearings are supplied with pressed steel cage and cooper alloy machined cage.

In bearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.

There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).

The outer and inner rings of all types are separable.

Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings 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.
Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings.

NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.

The inner ring loose rib of an NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside.

Features

1. Improved seal: Contact seal increases resistance to entry of water or foreign substances.
2. High load capacity: When used as a sheave bearing, radial and axial load capacities are increased
3. Corrosion resistance: Phosphate surface treatment improves resistance to rust.
4. Easy to apply grease: Holes provided on inner ring facilitate grease replenishment, even while the bearing is mounted.
5. Fewer surrounding parts: With snap rings for the outer ring, fewer parts are required around the bearing for a more cost-effective sheave.
