A rotary lip seal that presses into the housing bore and rides against the turning shaft, the DBH 8227 keeps oil or grease where it belongs and keeps contaminants out. It measures 51 mm at the shaft, 68 mm at the housing and 9.50 mm in height, and it carries the Lz design. Gearboxes, pumps, motors and similar drive equipment are the usual homes for a seal this size. MR Industrial Accessories LLC supplies this brand and can help you match it to your application.

The part is listed under the designation 8227 within the DBH seal range. Reading the number and the size string together tells you what you have: shaft 51 mm, housing 68 mm, height 9.50 mm, Lz configuration. In practice the elastomeric lip contacts the shaft while the metal outer case holds the seal in the bore, and the Lz layout refers to a lip-and-spring construction intended for rotating service. That combination of dimensions and design is what makes the 8227 identifiable on a data sheet.

Seals of this size turn up in gear reducers, centrifugal pumps, electric motors, compressors and belt or chain drive assemblies. Machine tools, food processing lines and hydraulic circuits that need to hold oil or grease and shield bearings from dust and moisture are also common users. Medium-power equipment is where the compact envelope fits most often.

Installation rewards care. Confirm the bore and shaft are clean, with no burrs or nicks, and that the shaft surface is hard and smooth enough for the lip to run on. Coat the lip with the same lubricant the machine uses before you slide it into place. Keep the seal square to the shaft and drive it in with a tube whose outside diameter matches the case, applying force to the case rather than the lip. If the bore is deeper than the seal, seat it at the original depth.

Looking for a cross-reference? Send the full part number, the shaft, housing and height measurements, and a photo of the old part. With that information we can search the same brand or another line we carry. We can also talk through lip type and material based on the fluid and the temperature the equipment sees.
