The DBH 8612Sil is a single-lip radial shaft seal designed for rotating shafts in gearboxes, pumps, and medium-sized electric motors. It mounts in cylindrical housings to retain lubricant and keep contaminants out. With a 39.70 mm shaft diameter, a 62.00 mm housing diameter, and an 11.00 mm height, it fits common industrial assemblies. MR supplies this seal and can help you confirm the right variant for your application.

The 8612Sil carries the DBH designation and measures 39.70 mm at the shaft, 62.00 mm at the housing, and 11.00 mm in height. Its Lx-H-H design combines a single sealing lip, a metal body, and an auxiliary exclusion lip, making it suitable for permanently lubricated rotating shafts. The lip elastomer is formulated to handle common industrial oils and greases, while the internal spring keeps contact pressure on the shaft throughout service.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers, and power transmission equipment. In each case it performs two jobs: holding lubricant inside the assembly and blocking dust, water, or particles that would speed up wear on bearings and gears. Because compatibility depends on exact shaft and housing dimensions, it is a frequent replacement item in industrial maintenance.

During installation, check that the shaft has the correct hardness and surface finish and is free of burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in with a support tube that contacts the outer diameter only, never the lip. The 11.00 mm height helps in tight spaces. If the shaft shows wear, consider a seal with the lip positioned differently.
