SPECIAL RADIAL CLEARANCE BETWEEN ROLLER TRACK AND ROLLER IN SPHERICAL ROLLER BEARING FOR 100 - 120MM CYLINDRICAL BORE

摘要

A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement The bearing makes many of the machines we use every day possible. Vibrating screen, Stone crusher and Compactor have inherent eccentric motion, a range of strong and robust spherical roller bearings are developed for these application. The Special Radial Clearance between roller track and roller in Spherical Roller Bearing for 100 - 120mm Cylindrical Bore comprises of smooth rollers present in between the inner and outer metal surface in order to reduce the friction between the surfaces along with thermal expansion. The minimum clearance developed by us for special spherical roller bearing of diameter 100 -120mm between inner ring, outer ring and roller is 140 whereas in normal case it is 75 and the maximum clearance between inner ring, outer ring and roller is 185 whereas its 120 in normal case. This shows that there is an increment of 86.7% in minimum clearance and 54.16% increment in maximum clearance. Both extended clearances may be varied further upto ±25%.
