MB Series Spherical Roller Bearings

Send Message Request a Quote

The MB series spherical roller bearing is characterized by a two-body cage, two rows of symmetric sphered rollers, and an inner ring with a center flange and a small flange. Being the modification of traditional design, the MB series spherical roller bearing has longer life than traditional ones and is applicable to working conditions with oscillating loads and extremely high speed. However, bearing loads for the MB series are a little lighter than those for the CA series.
