NTN NU3 Series single row cylindrical roller bearing.
NTN NU3 series cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.

Features
- Non-locating bearings: cylindrical roller bearings nu and n are non-locating bearings and can support radial forces only. in series nu, the outer ring has two ribs, while the inner ring has no ribs. bearings n have two ribs on the inner ring and an outer ring without ribs
- The outer and inner ring can be axially displaced relative to each other from the central position by the value "s"
- Semi-locating bearings, cylindrical roller bearings NJ are semi-locating bearings. Semi-locating bearings can support not only high radial forces but also axial forces in one direction and can therefore guide shafts axially in one direction. They act as non-locating bearings in the opposite direction. The bearings have two ribs on the outer ring and one rib on the inner ring
- Bearings with L-section ring: Non-locating bearings NU can be combined with an L-section ring HJ to form a semi-locating bearing unit, they must not be installed with two L-section rings (due to the risk of jamming)
- The outer and inner ring can be axially displaced relative to each other in one direction only by the value "s"
- Cylindrical roller bearings NUP and NJ with HJ are locating bearings, they can support not only high radial forces but also axial forces in both directions and can therefore guide shafts axially in both directions
- Bearings with rib washer: type NUP has two ribs on the outer ring and one rigid rib on the inner ring, a loose rib washer is fitted on the opposite side
- Bearings with L-section ring: non-locating bearings NJ can be combined with an L-section ring HJ to form a locating bearing unit. This design has two ribs on the outer ring, one rib on the inner ring and an L-section ring for the rib less side of the inner ring. The L-section rings suitable for the bearings are indicated in the dimension tables. The bearing and L-section ring must be ordered separately
- L-section rings: l-section rings are advantageous where, under high loads, the seating surface of the inner ring in NUP bearings with a loose rib washer is too small to provide a sufficiently high bearing seat. in some applications, they make it easier to fit and dismantle the bearings
- The bearings are supplied without seals sealing
- They can be lubricated from the end faces using grease or oil
- Single row cylindrical roller bearings with cage can be used at operating temperatures from -30 to +150 °C, increased capacity design
- Two-piece, roller-guided cage
- For continuous operating temperatures above 120 °C
- Clearance: C3, Speed Rating: 10900 rpm Limiting, 7500 rpm Reference
