In order to meet severer condition onto rubber rollers, staffs of our technical department devote themselves constantly to develop peculiar rubber compound for covering severer line condition of the customers. [...]


1. The shaft must never be operated without water.

2. The clearance shown in the above list is to be considered for the application at normal temperature of water. When the water temperature reads more than 30°C, it is recommendable to have a little bigger clearance.

3. When inserting the shaft into our rubber bearings, any grease or oil must not be used. Soapy water is recommendable for the purpose.

Precautions at design

●Allowable PV value
ince allowable contact pressure is set as 6 (kgf/cm2) and allowable peripheral speed is set as 12 (m/sec), the allowable PV value becomes 6 × 12 = 72 (kgf/cm2・m/sec).

●Water supply amount
Supply an amount of 2 × bearing inside diameter (cm) = Q (l/min).

●Tolerance of the bearing outside diameter
It is based on clearance fit, in principle. [...]
