Spare part bearing Cylindrical Roller Bearings N1010

spare part bearing Cylindrical Roller Bearings feature:

Cylindrical roller in line contact with the roller bearings. Load capacity, mainly bear radial load. Rolling ring wall with small friction, suitable for high-speed rotation. Whether under the ring wall, divided NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN double-row bearings. The bearing is the inner, outer separable structure. No inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as the free end of the bearing. In the inner and outer rings on one side of a double wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy machined cage. But there are also part of the use of polyamide forming cage.

1. Roller and raceway contact or repair off the assembly line for the line contact, the radial load capacity, suitable to withstand heavy load and shock load.

2. Friction coefficient is small, suitable for high-speed, speed close to the deep groove ball bearings.

3. N type and NU type can move axially, can adapt to errors due to thermal expansion or installation of the shaft and housing caused by changes in relative position can be used for supporting the free end.

4. On the shaft or housing bore machining are higher, and bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.

5. Detachable inner or outer ring for easy installation and removal.

spare part bearing Cylindrical Roller Bearings Main purposes:

Medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen, and lifting and transportation machinery.

Cylindrical roller bearings with inner and outer wall or ring are, in the radial loads but can also withstand a certain degree of axial load. At this time of the axial load capacity depends on the roller face situation, the bearing capacity of wall, lubrication conditions and speed, etc.

spare part bearing Cylindrical Roller Bearings Cage

Single row cylindrical roller bearings are machined solid cage used, stamping cage, nylon racks. Double row cylindrical roller bearings are machined brass cage with, and sometimes also available nylon cage. Four-row cylindrical roller bearings are machined brass cage used on the larger size pillar system of entities should adopt the car cage.

spare part bearing Cylindrical Roller Bearings Cage code flags are as follows:

1, the use of punch holder, rear cage code symbol J, if the frame structure of a variety of different stamping, followed by J, J1, J2 ... that

2, using Groove holder, rear cage code symbol CJ;

3, with solid brass cage, the cage post code flag M;

4, when the bearing outer diameter D> 400mm, the use of steel solid cage, cage code does not post signs, but if the inside and outside the boot, then a corresponding flag cage materials and guidance post-code means ( outside the guide for the A, the guide to B).

Double row cylindrical roller bearings with solid brass cage not sign.

spare part bearing Cylindrical Roller Bearings Radial clearance

single row cylindrical roller bearings have a basic set of standard products, radial clearance, can also provide C3, C4 group clearance.

double row cylindrical roller bearings standard product with C1 group clearance, cylindrical bore also provides C2, C3 group clearance, tapered bore bearing clearance can also provide C2 group.

 spare part bearing Cylindrical Roller Bearings Size range

cylindrical roller bearings the basic dimensions are listed in the data table size,

Diameter size range: 25mm ~ 1900mm

Diameter size range: 52mm ~ 2300mm

Width range: 13mm ~ 400 mm

spare part bearing Cylindrical Roller Bearings Tolerance

P4 production tolerances below the rank of one, two, four-row cylindrical roller bearings, machine tool spindles also produced a special tolerance class SP, UP-class double row cylindrical roller bearings.
