In the huge system of industrial equipment, although the bulk roller bearing is small in size, it plays a vital role. With its unique structure and excellent performance, it provides a solid guarantee for the stable operation of many mechanical equipment.

1. Performance characteristics of bulk roller bearings

Bulk roller bearings are mainly composed of inner ring, outer ring, roller and cage. Its roller is cylindrical, and its length is greater than its diameter. This design enables it to withstand large radial loads. During operation, the roller is in close contact with the inner and outer rings, and rolling friction replaces sliding friction, which greatly reduces the friction coefficient, reduces energy loss, and improves mechanical transmission efficiency. At the same time, it also has high rotation accuracy, can maintain stability under high-speed operation conditions, reduce vibration and noise, and extend the service life of the equipment. In addition, the bulk roller bearing also has good adaptability and can work stably under different temperature, humidity and load conditions. Whether it is severe cold or heat, or high humidity and high corrosion environment, it can stick to its post.
