The DBH 9807/85 is a radial shaft seal used to keep lubricant in and contaminants out of rotating equipment. It is identified by the designation 9807/85 and its dimensions are shaft 25 mm, housing 34 mm, and height 5.00 mm. The Lz design has a single sealing lip with a spring, making it suitable for lubricated rotating shafts. This seal is a wear item and should be replaced when oil loss or shaft play is noticed. MR Industrial Accessories supplies this brand and can help you select the right seal for your application.

The 9807/85 belongs to a series of seals that share the same nomenclature but come in different dimension combinations. For this specific part, the confirmed measurements are 25 mm shaft diameter, 34 mm housing diameter, and 5.00 mm height. It is a standard component within the range of seals and oil seals that MR distributes.

Typical uses for a seal like the 9807/85 include gearboxes, electric motors, centrifugal pumps, speed reducers, and transmission equipment. In these applications, it retains oil or grease inside the assembly and blocks dust, water, or particles that could damage bearings. Its 5 mm height also makes it suitable for fan shafts, compressors, and machine tools where axial space is limited.

When selecting a replacement, verify that the shaft and housing dimensions match those of the original seal. The shaft surface should be ground and free of grooves; excessive roughness can accelerate lip wear. The housing should have an entry chamfer to prevent damage during installation. The 5.00 mm height determines the housing depth; if the space is deeper, a shim may be required. The Lz design is intended for moderate peripheral speeds and low pressures.
