The DBH 1181Pol is a radial shaft seal from the DBH line, sized 24.50 mm shaft diameter, 42.00 mm housing diameter and 6.00 mm height. Its Lz-R H design combines a main retaining lip with a dust lip, so it keeps lubricant in and contaminants out on rotating shafts. MR Industrial Accessories supplies this seal as part of its seals and oil seals range.

Reading the code helps you match the part: 1181Pol identifies the size and construction within the DBH line, while Lz-R H tells you the seal has a retaining lip plus a dust lip. The 24.50 x 42.00 x 6.00 mm dimensions correspond to shaft, housing and height, so confirm all three against the original before ordering.

You will find this type of seal in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment, wherever a shaft turns inside a housing and oil or grease must stay separated from the outside. In dusty or splash-prone areas, the dust lip of the Lz-R H design helps protect the main lip. Treat it as a wear part and replace it during preventive maintenance.

Correct installation matters as much as the dimensions. Lubricate the lip with the same oil or grease used in the equipment, clean any burrs from the housing, and avoid hitting or deforming the seal during insertion. Shaft finish and tolerance also affect sealing: a scratched or worn shaft can leak even with a new seal, and good shaft-to-housing alignment prevents lateral stress on the lip.

If you need an equivalent or a close variant, send us the original code, your measurements or a photo of the part. In many cases an alternative design can fit the same housing as long as functional tolerances are respected. We review options within the brands we carry and help you choose what works for your equipment.
