120x55x29 mm 30311D 30311C3 30311V2 Taper Roller Bearing P0 P4 P2 Quality Level Product introduction - Tapered roller bearings mainly bear radial and axial combined loads. Bearing bearing capacity depends on the raceway angle of the outer ring. The larger the carrying capacity. This type of bearing is a separate bearing, which is divided into single, double and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing.
- The angle is between 10 degrees and 19 degrees. It can withstand the joint action of axial load and radial load simultaneously. The bigger the contact angle is, the greater the capacity will be.
- inner diameter size range: 20 mm to 1270 mm
- diameter size range: 40 mm to 1465 mm
