3. Most of the metal case of oil seal have a grinded outside diameter. For some large thermal expansion housing especially for aluminum and magnesium, the outside diameter is covered in rubber.

Note:
1. Models and Logos can be Customized according to your Requirement
2.we can produce according your drawings and samples.
