Cylindrical Roller Bearing For Dynamo
Cylindrical Roller Bearing For Dynamo
cylindrical roller bearings are bearings in which cylinders are used as the rolling elements as opposed to balls in ball bearings.As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface.Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical Roller Bearings have high radial rigidity and are used primarily for precision machine tools.
Cylindrical Roller Bearing For Dynamo
Cylindrical roller and raceway for linear contact bearings. The load capacity is large, mainly bearing radial load. Rolling body and the sleeve edge friction is small, suitable for high-speed rotation. According to the sleeve has no edge, can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is the inner ring, outer ring can be separated structure.
Inner circle or outer circle without blocking edge cylindrical roller bearing, its inner circle and outer circle can make relative movement to the axial direction, so it can be used as a free end bearing. In the inner circle and outer circle of a side of the double retaining edge, the other side of the collar has a single retaining edge of the cylindrical roller bearing, can bear a certain degree of a directional axial load. General use of steel plate stamping cage, or copper alloy turned solid cage. However, there is also a part of the use of polyamide forming cage.
