Surface Hardening Taper Roller Bearing , 30305 / 30315 Carburizing Bearing Steel

Basic information

Conical inner ring and outer ring raceway, the tapered roller are arranged in between. All the projection line on the surface of the cone axis in bearing the same points together. This design makes the tapered roller bearing is especially suitable for composite under radial and axial load. Bearing axial load capacity is mostly determined by the contact Angle alpha and alpha Angle, the greater the axial load capacity is higher. Angle size by calculating coefficient of e; E value, the greater the contact Angle, the greater the bearing axial load of the greater applicability. Tapered roller bearings are usually separated type, namely by inner ring with roller and cage components consisting of conical inner ring components can be installed separately from the cone outer ring (outer ring).With logarithmic contact shape in roller/roller interface provides optimum stress distribution. Guide flange and roller large end sliding on the surface of the special design, will significantly promote the formation of oil film on the surface of the roller end/flange contact. And include reliability enhancement, the benefits of reduced susceptibility in the wrong.

Metric bearing

Listed in the product table metric of single row tapered roller bearing dimension conform to ISO 355-1977 standard.
