Thrust Cylindrical Roller Bearings

★　Product Characteristics

Thrust Cylindrical Roller Bearing comprises washer raceway ring (blowout patch, seat ring) and components of cylindrical roller and holder. The cylindrical roller is processed by convexity, so the pressure between roller and raceway surface is evenly distributed.

This type of bearing is provided with separable structure, and blowout patch, seat ring and roller body components can be separately mounted. When mounting, the shaft is not allowed to incline relative to housing axis.

This type of bearing is applied in low speed situation. It can be subject to unidirectional load, but radial displacement can not be limited. The axial load capacity is great, and the axial rigidity is large.

●　Product Classification

Unidirectional thrust cylindrical roller bearing

Bidirectional thrust cylindrical roller bearing

■　Size Range

Inner diameter range:30mm～1180mm
Outer diameter range:52mm～1400mm
Width range: 16mm～100mm

◆　Tolerance

ZWZ thrust cylindrical roller bearing tolerance is implemented according to GB307.4. ZWZ can offer P0, P6,P5 grade products.

★　Holder

ZWZ thrust cylindrical roller bearing mainly adopts brass sweeping entity holder.

When bearing outer diameter D≤500mm, brass entity holder is adopted, and the postposition code is not marked. When bearing outer diameter D>500mm, steel entity holder is adopted, and the postposition code is not marked, but corresponding postposition codes of other holders should be marked.
