The DBH 8891 is a radial shaft seal that keeps lubricant in and contaminants out of rotating shaft assemblies. With a 45.00 mm shaft diameter, 55.00 mm housing bore and 7.00 mm overall width, it fits applications where axial space is tight. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

This seal carries the DBH brand and part number 8891. The size code breaks down as shaft 45 mm, housing 55 mm, width 7.00 mm. Its Lx design uses a sealing lip with a spring, a common configuration for rotating shafts. The seal is designed to be press-fit into a machined housing bore as a standard replacement component.

Typical installations include gearboxes, pumps, electric motors, transmission shafts and other industrial machinery. The seal performs two jobs: it holds oil or grease inside the assembly and blocks dust, water and particles from entering. You will find it in applications where the shaft turns at moderate speeds and a dependable barrier between lubricant and environment is needed.

When selecting a replacement, match the shaft, housing and width dimensions to the existing bore. The shaft surface should be ground and free of splines to prevent lip damage. During installation, coat the lip with the same oil used in the equipment and use a support tube to avoid deforming the seal. For worn shafts, consider a seal with an auxiliary lip.
