The DBH 8719 is a radial shaft seal built to hold lubricant in and keep contaminants out of rotating assemblies. It measures 51 mm at the shaft, 58 mm at the housing and 4.00 mm in height, and it uses the Mt design. Because it is a wear part, leakage or dirt ingress is the signal to replace it. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for your equipment.

This seal carries the designation 8719 and is a single-lip radial shaft seal. The Mt design refers to a metal-bodied seal with a sealing lip, which is pressed into the housing bore. Shaft 51 mm, housing 58 mm, width 4.00 mm. That combination suits tight axial spaces where a low-profile seal has to run against the shaft and seat in the housing.

You will find this seal in gearboxes, pumps, electric motors, rollers and transmission equipment, wherever a rotating shaft needs to be sealed against oil or grease loss. It also serves as a barrier against dust, water and particles reaching bearings and gears. The 4 mm height makes it a common choice in assemblies with limited axial room.

Before installation, confirm the shaft measures 51 mm, the housing bore 58 mm and that 4 mm of height is available. Clean the shaft and check it for burrs or marks, then lubricate it before sliding the seal into place. The lip should face the fluid side. If the shaft is worn, a seal with the lip in a different position may be the better option. Aligning shaft and housing correctly helps prevent early leakage.
