The DBH 8842 is a radial shaft seal built for rotating shaft assemblies, keeping lubricant where it belongs and holding dust, water and particles out. It measures 105 mm at the shaft, 135 mm at the housing bore and 13.00 mm in height, and it comes in the Lz design. MR Industrial Accessories supplies this brand and can help you match the seal to your equipment.

Reading the code helps when you order. DBH identifies the brand and 8842 is the reference for this seal. The three figures that matter are shaft 105 mm, housing 135 mm and height 13.00 mm. The Lz designation describes the lip and profile arrangement: the seal presses into the housing and its elastomeric lip, usually backed by a spring, rides against the shaft to close off the assembly.

Seals in this size range turn up in gearboxes, pumps, electric motors, rollers and other power transmission equipment, as well as in agricultural and road machinery and plant processes where grit or moisture would otherwise reach the bearings. Any arrangement with a shaft turning inside a housing and oil or grease to be kept separate from the surroundings is a candidate.

Selection starts with the three dimensions, then the height you have room for. Look at the shaft surface as well: scratches, wear or a poor finish will shorten seal life no matter how good the part is, and the housing bore needs the right finish and tolerance. When fitting the seal, coat the lip with lubricant and press it in with a tool that spreads the force evenly so the lip is not damaged. For high speed or high temperature service, contact us to review lip material and spring type.

If you are after a seal equivalent to the DBH 8842, send the full code, the shaft, housing and height measurements, and a photo of the part you are replacing. With that we can check options among the brands we carry or propose a compatible replacement, and we can also look at adapting a size while staying within the tolerances of the assembly.
