NUP (RIP, RP)

Cylindrical bearing type NUP has a double ribbed outer ring and a single-ribbed inner ring with an abutting loose rib, which allows the bearing to provide axial location and to carry light thrust loads in both directions. Factors governing radial and thrust load capacities are the same for type NJ.

Size range: 80 mm to 2000 mm OD

Design Attributes

Design features an outer ring with two integral ribs and an inner ring with a single rib.
Features an abutting loose rib.
Carries light thrust loads in both directions.
Provides axial location.
May be used with RN or RU bearing to accommodate axial expansion/contraction.

Applications

Cement making equipment such as crushers; vertical, ball and rolling mills; conveyor drives; gear reducers, spherical pillow blocks; trunnions and rotary kilns
Power generation equipment such as pulverizers, gearboxes and gear drives
Oilfield equipment such as mud pumps, drawworks, swivels, block hooks, crown blocks, traveling blocks and top drives

NF (RIF, RF)

Cylindrical bearing type NF has single-ribbed outer and double-ribbed inner rings and can support heavy radial loads, as well as light unidirectional thrust loads up to 10 percent of the radial load. The thrust load is transmitted between the diagonally opposed rib faces in a sliding rather than a rolling motion.
Size range: 80 mm to 2000 mm OD

Design Attributes

Design features outer ring with one integral rib and an inner ring with two ribs.
Supports heavy radial and light unidirectional thrust load up to 10 percent of radial load.
Angle ring can be used to turn a floating bearing into a fixed one.

Applications

Cement making equipment such as crushers; vertical, ball and rolling mills; conveyor drives; gear reducers, spherical pillow blocks; trunnions and rotary kilns
Power generation equipment such as pulverizers, gearboxes, and gear drives
Oilfield equipment such as mud pumps, drawworks, swivels, block hooks, crown blocks, traveling blocks and top drives

N (RIN, RN)

These bearings carry radial load only and can accommodate both expansion and contraction. The relative axial displacement of one ring to the other occurs with minimum friction while the bearing is rotating. Type N bearings may be used in one or two positions for shaft support if other means of axial location are provided. The outer ring has a cylindrical bore without ribs and the inner ring incorporates two ribs.
Size range: 80 mm to 2000 mm OD

NU (RIU, RU)

These bearings carry radial load only and can accommodate both expansion and contraction. The relative axial displacement of one ring to the other occurs with minimum friction while the bearing is rotating. Type RIU and RU bearings may be used in one or two positions for shaft support if other means of axial location are provided. The outer ring has two integral ribs while the inner ring has a cylindrical outer diameter without ribs.

Size range: 80 mm to 2000 mm OD

Design Attributes

Design has a cylindrical inner ring and two ribs on the outer ring, making type NU bearings well suited for use as floating bearings.
Separable components simplify mounting and removal.
Accommodates axial expansion and contraction.
Provides axial displacement between rings with minimum friction while rotating.
Supports heavy radial loads.
Not suitable for applications with thrust loads.
