MB SeriesSelf-aligning Roller Bearings

MB Type: An improved design based on the traditional structure, featuring reinforced symmetrical rollers and a two-piece brass alloy cage, with the inner ring fitted with a central flange. With the same design load as the CC type, it offers high rated load capacity and a long service life.

These bearings are widely used in mining vibration machinery, vibrating screens and vibration motors, and are one of the key components in such equipment. These bearings operate under harsh conditions, characterised not only by high ambient humidity, high levels of dust particles, high rotational speeds and high temperatures, but also by severe vibration and impact, resulting in extremely high operational loads.

The bearings offer the advantages of high load-carrying capacity, excellent impact resistance, high reliability and good lubrication performance, whilst also being able to accommodate shaft deflection. Generally, dimensional tolerances are P6 and running tolerances are P5; these tolerances are fixed and can be measured according to either imperial or metric standards. Due to the high heat generation of the bearings, the clearance is typically set quite generously. This clearance can be calculated based primarily on the original clearance, tolerance fit and temperature rise.
