Professional cylindrical roller bearing manufacturer with ISO9001:2000 certificate
we are professional cylindrical roller bearing manufacture with ISO9001:2000 certificate.
The cylindrical roller bearings are separable bearing. The roller contact raceway with line-contact. Therefore, the radial load carrying capacity is higher and applies to heavy load, impact load or high rotating speed circumstance. This bearing is easy to be installed and disassembled, especially when the inner ring and outer ring needed to interference fit with shaft and housing. The cylindrical roller bearing can be divided into single-row, double-row and four-row cylindrical roller bearing according to the row of rollers. Besides, there are some other types of bearing such as full complement cylindrical roller bearing.
