The highest vibration levels are characteristic of vibroscreens, road rollers and sawmills. All bearings, which are used in these machines must provide high rotation speed, perceive increased loads, speeds, centrifugal forces, and node operating temperature. In addition, dirt and moisture are additional adverse operating factors. All these conditions promote increased bearing runout and as a result, its failure.
R&D specialists of BBC group conducted a thorough research of this problem. Existing solutions that are used by leading industry experts were analyzed, and their own developments were formed and put into production. For using these innovative solutions, the company’s engineers designed and launched the technological production process of a new bearing line – vibration-resistant bearings BBC-R EXV (extreme vibration). During the 1st half of 2020, these bearings were tested at various enterprises throughout EU countries. By July of this year, all tests were successfully completed. Installed vibration-resistantbearings BBC-R EXV, showed a high level of durability and complied all the necessary operating requirements. To date, a new line of products has been launched into serial production.
The innovative design of BBC-R EXV vibration-resistant bearings is optimised for vibration equipment.
A reinforced three-element separator with centering guide ring with hardened surface ensures the operation of the bearing with minimal internal friction and operating temperature, which increases its service life.
BBC-R EXV vibration bearings are made of stainless steel from leading manufacturers.
Special CS enlarged radial internal clearance compensates temperature expansion and ensures uninterrupted bearing operation even at elevatedtemperatures.
Additional treatment of mounting surfaces provides reduced tolerances on the overall dimensions of the inner and outer rings.
Additional treatment on the working surfaces of the bearing parts reduces friction between the working surfaces of the bearing and better guides the movement of the rollers, which has a positive effect on rotation speed and load distribution.
The vibration-resistant BBC-R EXV bearings are resistant to:
– high rates of vibration;
– to the shock nature of unevenly distributed loads;
– to increased speed;
– to high temperature.
