CHROME STEEL Taper Roller Bearing
Product introduction
NJ 307ET2XU Cylindrical Roller Bearing is a type of rolling element bearing
that is designed to provide support for radial loads, which are
perpendicular to the axis of rotation.
It consists of an inner ring, an outer ring, cylindrical rollers,
and a cage that holds the rollers in place.
The inner and outer rings of a cylindrical roller bearing are
typically made of steel and are machined to precise dimensions. The
cylindrical rollers are also made of steel and are arranged
parallel to the axis of rotation. The cage,
usually made of brass or steel, holds the rollers evenly spaced
apart and prevents them from coming into contact with each other.
Cylindrical roller bearings are commonly used in various machinery
and equipment,
