The DBH 9835/85 is a radial shaft seal from the DBH line, built for rotating shafts where lubricant retention and contamination exclusion are required. It follows an Lz design, meaning a single lip with a spring. The dimensions are shaft 20.60 mm, housing 41.40 mm, and height 6.60 mm. This seal is a common replacement item in industrial equipment, and MR supplies it as part of its seals and oil seals range.

In a seal designation like DBH 9835/85, the numbers identify the size and the Lz suffix describes the lip configuration. The 20.60 mm shaft diameter, 41.40 mm housing diameter, and 6.60 mm height must match the bore and shaft of your equipment for a proper fit. The Lz design uses a single sealing lip with a spring, intended for rotating shafts with lubrication. The elastomer lip runs against the shaft while the outer body seats in the housing. Because it is a precision component, mounting must be done without damaging the lip.

Typical installations include gearboxes, pumps, electric motors, rollers, machine tools, conveyors, and transmission systems. The seal keeps oil or grease inside the assembly and blocks dust, water, and particles from entering. When it fails, lubricant escapes and contaminants reach the bearings and gears, which accelerates wear. For that reason, replacement is recommended whenever the assembly is opened.

Selection starts by confirming the three dimensions against your housing and shaft. The Lz design is suited to medium speeds and low pressures. During installation, lubricate the lip and use a tool that does not deform it. If the shaft surface shows wear or roughness, consider repairing it or choosing a seal with an auxiliary lip.
