For equipment with a rotating shaft, the DBH 8430/85 radial shaft seal keeps oil or grease where it belongs and keeps dust and water out. Its size — shaft 20 mm, housing 35.50 mm, height 9.60 mm — fits gearboxes, pumps, electric motors and small transmissions. MR Industrial Accessories supplies this brand and helps you select the right seal based on lubricant, speed and shaft condition.

This radial shaft seal comes from DBH and carries part number 8430/85. The dimensions are 20 mm for the shaft, 35.50 mm for the housing and 9.60 mm for the height. Design A 116 describes the lip geometry and metal body. It is a replacement component that seals the shaft where it passes through the housing, holding lubricant in and blocking outside contaminants.

You will find this seal in applications where a 20 mm shaft turns inside a 35.50 mm housing: gearboxes, centrifugal pumps, electric motors, compressors, mixers and belt or chain drives. It also shows up in machine tools, washing equipment and conveyor systems. Any time a rotating shaft needs to contain oil or grease, a seal like this handles the dynamic sealing job.

During installation, inspect the shaft for burrs or wear and make sure the housing is clean and free of dents. Apply the same grease or oil used in the equipment to the lip before pressing the seal in. Use a tube or press that contacts the outer ring only, never the lip. If the shaft has a deep groove, an offset lip seal may be a better choice. Peripheral speed and operating temperature also affect which compound you should select.

If you need an equivalent, send part number 8430/85 or the shaft, housing and height dimensions. With that information we check the catalog for the best match, whether from this brand or another we carry. We can also guide you on lip design and seal material based on the fluid and service conditions.
