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

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 bearing roller manufacturer, ZWA Bearings produces the rollers in house, from the first step purchasing the raw material to the last step finish grinding. ZWA adopts European standard steel and all rollers are up to grade II.

Single-row spherical roller bearings are self-retaining and they can handle both radial and thrust loads. Bar contact is another feature of single-row spherical roller bearings.

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.
