The DBH 9657 is a radial shaft seal built to the A 201 design. It keeps lubricant in and contaminants out of rotating equipment. The seal sits on a shaft that turns inside a housing, and its elastomeric lip presses against the running surface. Because it is a wear part, a hardened or damaged lip will show up as oil loss and the seal must be replaced. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the job.
This radial shaft seal carries the code 9657 and the A 201 design. A 201 means a single lip with a spring, a general-purpose configuration for rotating shafts. The 9657 number is the manufacturer's designation for this particular size and setup, not a universal size code.
You will find seals of this type in gearboxes, pumps, electric motors, rollers and power transmission equipment. They do two jobs: hold oil or grease inside the assembly and keep dust, water and particles out. Where vibration or temperature swings are present, the lip has to stay in contact without overheating, which makes the choice of lip and spring material as important as the dimensions.
Installation calls for a clean, burr-free shaft. Lubricate the lip before sliding it into place and use a support tube so the lip is not damaged. How the lip sits relative to the direction of rotation, and how concentric the housing is, both affect service life. A worn shaft can often be handled with a repair sleeve. We review these points with you before quoting.
For an equivalent, send code 9657 together with the shaft and housing dimensions, a photo of the part and the fluid being sealed. With that information we search for options in the same series or in compatible designs. If the environment calls for it, we can also supply the seal in a different lip material.

Frequently asked questions
- What does the A 201 design mean on this oil seal?
- A 201 identifies a single-lip seal with a spring, a standard configuration for general use on rotating shafts. It retains lubricant and excludes contaminants. Check the manufacturer's data sheet with code 9657 to confirm it fits your equipment.
- How do I request the replacement for the 9657 oil seal?
- Send us on WhatsApp the code 9657, the shaft and housing dimensions, and a photo of the part. With that data we verify the designation and look for an equivalent within the same DBH line.
- What should I keep in mind when installing a radial shaft seal?
- The shaft must be clean, burr-free and lubricated before the lip slides on. Use a support tube to avoid damaging it and check the concentricity of the housing. If the shaft is worn, consider a repair sleeve before installing the new oil seal.
