Individual bearing (ball or cylindrical roller child bearing), with columns (with column number), drive way (transmission belts, gears, motors, built-in motor), lubrication (grease, oil and gas, oil mist, spray) and other spindle parameter to determine its structure.
1, bearing radial load
Bearings mainly take radial load for radial bearings. Type of bearing nominal contact angle a0 <= 450. Ft rain same roller bearing load than the radial direction of the ball bearings can withstand greater.
N type and NU type cylindrical roller bearings can only support radial loads, and other types of radial bearings can bear radial load, also can withstand the axial load.
2, the axial load of the bearing
The axial load bearing general thrust bearing, its nominal contact corner a0> 450. Thrust bearing and thrust angular contact ball bearings under different structures can withstand the axial force in one or two directions. When withstand particularly high force preferred thrust cylindrical roller bearings and thrust self-aligning roller bearings.
Thrust Spherical roller bearings and one-way thrust angular contact ball bearings can withstand axial and radial loads, and other thrust bearings can only support axial load.
3, bearing its own length compensation
Supporting a shaft and bearing are usually fixed bearing and swimming in the bearing structure of the portfolio. Swimming the bearings compensation axis length error and thermal expansion.
Of NU type and N-type cylindrical roller bearing is ideal for swimming bearings, these bearings themselves can compensate for length. Bearing inner and outer rings can be a tight fit.
4, sliding with length compensation
The inalienable bearing also can be used for swimming bearings. Such bearing two rings with no axial mounting surface. Therefore, bearing a ferrule activities can, in its bearing surface.
