Single Row Cylindrical Roller Bearing NU 2315 ,NUP 215 ,NUP 315

Specifications

Cylindrical roller bearings features

1 roller and raceway contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.
2 small friction coefficient, suitable for high speed, speed close to deep groove ball bearings, inner or outer ring detachable, easy installation and removal.
3. N type and NU type can move axially, to accommodate misalignment due to thermal expansion or of the shaft and the housing due to changes in relative position, can be used for supporting the free end.
4 pairs of shaft or housing bore machining higher, bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.
Cylindrical roller bearings
1. No outer wall and the inner wall N0000 type cylindrical roller bearings NU0000 bearing acceptable such large radial load, high speed limit, do not bind the axial displacement of shaft or housing, can not accept axial load .
2. Double row tapered roller bearing inner and outer rings with ribs Cylindrical roller bearings NJ0000 type, NF0000 bearing shaft or housing can be bound axial displacement in one direction, and can accept a smaller axial load. NU0000 + HJ0000 type, NJ0000 + HJ0000 type, NUP0000 type bearings in the axial clearance of imported bearings shaft or housing areas bondage axial displacement in both directions. And accept a smaller two-way axial load.

Type cylindrical roller bearings
  Cylindrical roller bearings types include: N, NU, NJ, NF, NUP, NFP, NH (NJ + HJ), NN, NNU, NNF, FC, FCD type
1. N bearing
No outer wall, the inner ring ribs on both sides. Allows the bearing axis relative to the axial direction between the two displacement directions. NU type ribs on both sides of the bearing outer ring, inner ring without ribs. Can allow the shaft between the bearing seat in the axial displacement in both directions. Therefore, such a structure is suitable for use as a mobile end bearings.
2. NU type bearings
Ribs on both sides of the bearing outer ring, inner ring without ribs. Can allow the shaft between the bearing seat in the axial displacement in both directions. Therefore, such a structure is suitable for use as a mobile end bearings.
3. NJ type bearings
Outer sides of wall, inner side with ribs. Can withstand a certain amount of axial load. NF type outer side has wall, inner sides of ribs. Also can withstand a certain amount of axial load. Therefore, such a structure is suitable for positioning the axial direction as a single bearing.
4. NUP bearings
Outer sides of ribs, the inner side of the band (fixed) single-wall, while the other side is detachable flat ring. Can withstand a certain amount of axial load.
5. NN bearings
The outer wall, the inner wall on both sides of the middle of the wall. Allows the relative bearing between the shaft in the axial direction of the displacement produced two, NNU type bearing outer ring ribs on both sides of the middle of the wall, inner wall. Allows the bearing axis relative to the axial direction between the two directions of displacement generated. Therefore, such structure is suitable for swimming-end bearings. The type of bearing retainer multi-use vehicles solid cage.
Double row cylindrical roller bearings
 
Double row cylindrical roller bearings simplest definition is rolling element is a cylindrical roller and is the two side by side bearing to the heart. Double row cylindrical roller bearings rolling element and the raceway is in line contact, so it is relative to the point contact bearings can withstand a greater load, and the rolling element and ring friction, for high-speed rotating machinery.
Due to large load capacity, high-speed two features, double row cylindrical roller bearings use a wide area, the main purposes are: cranes, large motors, vehicle bearings, generators, machine tool spindles.
Four cylindrical roller bearings Front codenamed FC, FCD, RY, RX, RXK type, they are for high-speed, high-temperature, high radial loads and design.
FC-type
FC-type four cylindrical roller bearing is composed of two outer and an inner ring composed of two outer sides and the middle has a wall, inner wall no.
CFD model
CFD-type four-row cylindrical roller bearings are composed of two cylindrical roller bearings NN combination.

Bearing purposes

Medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen and lifting and transport machinery.
