Features NSK Bearings	Benefits NSK Bearings
Special ultra-clean bearing steel made to NSK specifications. NSK Cylindrical rollers are specially contoured. Available in machined brass, steel and polyamide cages in most sizes. Standard, C3, special clearance, and electric motor quality are available for all sizes. "E" type supplied.	Ultra-clean steel delivers greater reliability and increased life. Relieves edge loading in your application with shaft misalignment. Tailors your bearing to your application requirements. Proper clearance selection helps cylindrical roller baring last longer and perform quieter. Increased capacity helps achieve additional bearing life.

NSK Cylindrical roller bearings are designed to carry heavy radial loads and are suitable for high
speed applications. Their rolling elements are ground to provide maximum contact with the raceway and
are precisely crowned to avoid edge loading due to shaft misalignment.

NU style single row - NU style bearings have two machined flanges on the outer ring and no flanges
on the inner ring.

N Style single row - N style bearings have two machined flanges on the inner ring and no flanges on
the outer ring, with rollers and cage on the inner ring. Like the NU style, the N has no thrust load carrying
capability.

NJ style single row - NJ style bearings have two machined flanges on the outer ring and a machined
flange on one side of the inner ring. The roller and cage assembly is in the outer ring. The integral flange
on the inner ring allows this bearing to carry an axial load.

NF style single row - NF style bearings have two machined flanges on the inner ring and one flange
on the outer ring, with roller and cage on the inner ring. Like the NJ bearing, these bearings have some
thrust load capability.

NH style single row - NH style bearings have two machined flanges on the outer ring and a machined
flange on one side of the inner ring. A special-design inner ring allows use of a stabilizing ring on the
non-flange side. As a result, these bearings can carry axial loads in both directions. The roller and cage
assembly is mounted in the outer ring.

NUP style single row - NUP style bearings are similar to the NJ style and come with a special ring often
called a thrust collar. Mounted on the non-flange side of the inner ring, the thrust collar allows the bearing to
carry an axial load in both directions. The thrust collar extends out of the bearing on one side, so the
dimension across the inner ring is slightly greater than that of the outer ring

Double row styles (NN, NNU) - Double Row cylindrical roller bearings are denoted by two N's within the
part number (e.g., NN or NNU).

S-Type - Sealed-Clean Bearings for chain conveyors demonstrate a high efficiency under high temperatures
and wet conditions for a longer period with an improved sealing system. These bearings are packed with a
quality grease of high thermal resistance and durability.

Continuous Caster Roller Bearings - These are 2-split bearing units of a highly reliable design and feature
a long service life. Cylindrical roller bearings with self-aligning rings having a proper alignment function.

Four Row Cylindrical Roller Bearings - Are also popular roll neck bearings providing several benefits.
First, the inner ring is separable form the outer ring and rollers which allows the inner ring to remain with the
roll during grinding processes. This assures precise concentricity and negligible run-out providing for high
rolling accuracy. Secondly, this design allows for greater radial load carrying and higher operating speeds.
Four row cylinders must be used in combination with a thrust bearing which is usually a two row taper,
angular contact ball bearings, or a deep groove ball bearing depending on the thrust load present.
