A radial shaft seal from the DBH line, reference 9811/85, built to sit in a housing and seal around a turning shaft. Read the code as shaft 35 mm, housing 50 mm, height 8.00 mm, with the A 016 design. Pumps, motors, gearboxes and transmission assemblies are the usual places this size shows up. MR Industrial Accessories supplies this brand, so the reference can be quoted directly.

The designation 9811/85 carries the size inside it, which makes cross-referencing simple when a seal has to be replaced. Shaft 35 mm, housing 50 mm, height 8.00 mm, A 016 design. The construction is a metal case with an elastomer lip, made for rotary service. A 016 points to one specific build within the DBH range; the lip profile and compound behind that code should be confirmed on the manufacturer's data sheet when the details matter for your application.

Two jobs are handled at once by a seal this size: keeping oil or grease where it belongs, and keeping dust, water and particles out. That is why it appears in centrifugal pumps, electric motors, gearboxes, reducers and power transmission equipment. Because the lip wears against the shaft, it is a service part. Replacing it on a set interval is what keeps leaks from starting and protects the bearings and gears around it.

Installation is straightforward but unforgiving of shortcuts. Shaft and housing should be clean, free of burrs and free of marks. Put a film of lubricant on the lip, then press the seal in square to the shaft, applying force on the case rather than the elastomer. How you select a replacement depends on shaft speed, operating temperature and the fluid being retained. Where peripheral speed runs high or temperatures are extreme, ask about the variant that fits those conditions. For most replacements, 35 x 50 x 8 mm is the reference that matters.

Quotes are handled by part number. Send 9811/85, or the dimensions 35 x 50 x 8 mm, through WhatsApp or email, and a photo of the old seal or the housing drawing helps as well. The team checks the designation against the manufacturer's data sheet and can suggest equivalents when the exact reference is not the only option. DBH is one of the brands MR Industrial Accessories supplies, alongside the rest of its seal range.

One check before fitting: look at the shaft surface where the lip rides. A worn track or a groove there will take a new seal out quickly, no matter how good the part is. If anything about the size or the application is unclear, send the reference 9811/85 and the team will help confirm it.
