The DBH 8163 is a radial shaft seal that sits in the housing and rides against a turning shaft. It keeps lubricant in and keeps dust, water and other contaminants out. With a 36 mm shaft, 48 mm housing bore and 10 mm width, it fits many gearboxes, pumps, motors and transmission units. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the job.

You can read the code in two parts. The 8163 is the designation, and the size follows the usual order: shaft 36 mm, housing 48 mm, width 10 mm. The Lx design is a single lip with a spring, made for rotating shafts that run with oil or grease. Because DBH is a brand we carry, you order by the exact part number and get the manufacturer's configuration.

Seals like this show up in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. The job is always the same: hold the lubricant where it belongs and keep contaminants out so bearings and gears do not wear faster. Treat it as a wear part. Replace it when you see a leak, or when the lip feels hard or shows cracks.

Installation is straightforward if you prepare the surfaces. Check the shaft for burrs or deep marks in the contact zone, and make sure the housing is clean and not distorted. Coat the lip with the same oil or grease used in the unit, then press the seal in with a tube or press that pushes on the outer diameter only. Never load the lip. If the shaft is worn, a wear sleeve is an option. Speed, temperature and the fluid in the system all affect the final choice.

Need a seal that matches the DBH 8163? Send the full part number, the shaft, housing and width dimensions, and a photo of the old part if you have one. We confirm whether that exact size can be quoted. If the Lx lip is not the best fit for your equipment, we can point you toward a different lip profile or material.
