Summary

Cylindrical roller bearings belong to separable bearings. They are mainly used for medium and large-sized power generators, internal combustion engines, combustion turbines, machine tool spindles, reduction gear.

Cylindrical Roller Bearing

Split cylindrical roller bearings are mainly used for crank and the position where bearings are difficult to be installed and are mainly used for fields such as a cold rolling mill crank of pigg steel tube, spine shaft, excavator, transmission mast of rolling mill and large-sized ventilation equipment.

SUNBEARING also can provide special single row cylindrical roller bearing for vibrating screen or other oscillating machinery, adopting turned solid brass cage. Radial bearing clearance often adopts the C4 group.

Full complement cylindrical roller bearings are designed to bear the heavy loads. Under the same width, such bearings have an extremely high bearing capacity, small radial cross-section, and saving space but relatively low rotation speed compared with traditional bearings with cage.
