Tapered roller bearing 30311 made in Japan
size:55*120*29mm,
row:single row,
seal:OPEN,
precision:P0-P6 precision,
usage: Large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc
coutry of origin:
Function: Mainly carry radial, axial combined load with radial load in the main.
The capacity of axial load carryin depends on the contact angle of
outer rings' raceway.
The bigger the contact angle is, the greater the capacity will be.
Tapered roller bearing
Tapered roller bearings are mainly used to bear radial load mainly radial and axial loads, generally should not alone bear the axial load. These bearings are designed to make the inner raceway, outer ring raceway and roller apex of the conical surface of the rolling surfaces intersect at a point bearing center line.
