ZWA's new mile stone in paper & pulp industry--Valmet

Toroidal roller bearings are kind of new single-row radial bearing. It has crowned symmetrical rollers and circular ring raceways.The rollers of the toroidal bearings are self-guiding, that’s to say they adjust the position in which the loads are averagely distributed over the length of the rollers no matter the inner ring is axial displaced or not. The raceways of the inner rings and outer rings are concave and arranged symmetrically about the center of the bearings.

Cylindrical roller thrust bearings consist of rollers, cage components, shaft ring and housing ring. Those components are separable for efficient and convenient operations.

Rollers is one of the most crucial part of roller bearings, whose precision will directly affect the precision and performance of the bearings.

As a leading China roller bearing supplier and manufacturer, ZWA Bearings produces the rollers in house, from the first step purchasing the raw material to the last step of finishing grinding. ZWA adopts European standard steel and all rollers are up to grade II.
