Urethane/Rubber Rollers - Bearing Type
Caution
Product Description
roller with a bearing that can be selected from various resins and hardnesses. There are two types of shapes: straight type and crown type.
The material of the core metal can be selected from steel (equivalent to S45C), stainless steel (SUS304), and aluminum (aluminum alloy).
For the lining, you can specify urethane (natural color), antistatic urethane (gray), silicone rubber (light gray), heat-resistant urethane (reddish brown), or NBR (black).
Shore hardness can be selected from Shore A50 to Shore A95. Please check the outline drawing and specification table for availability.
A90/95 is ether urethane, A50/A70 is ester urethane.
It is possible to specify dimensions in 1mm increments for the L specification type, but the length that can be specified for the L dimension selection type cannot be selected.
Additional machining (MC) allows tapping holes to be machined at two locations on the outside diameter. In addition, (UDC) allows you to change the urethane to antistatic urethane.
The bearing material can be changed to stainless steel type with additional machining (SB). Please refer to the specification table for the range of dimensions that can be specified.
