The DBH 5354 is a single-lip radial shaft seal built to keep lubricant in and contaminants out of rotating assemblies. Its Lz configuration combines an elastomer sealing lip with a metal outer case. The seal fits a 55 mm shaft, a 75 mm housing bore and has a 12 mm height, making it a direct replacement for common industrial sizes.

Key dimensions for part 5354 are shaft 55.00 mm, housing 75.00 mm and height 12.00 mm. The Lz designation indicates a single sealing lip with a spring, suitable for grease or oil retention on rotating shafts. The elastomer lip flexes to handle minor misalignment and vibration, while the metal case presses into the housing for a secure fit.

Typical installations include gearboxes, pumps, electric motors, conveyor rollers and other transmission equipment where lubricant loss or ingress of dust and water must be avoided. Because it is a wear component, inspect it whenever leaks, unusual noise or bearing play appear. The seal works best when shaft and housing dimensions and surface finish are within specification.

Before installation, verify the shaft diameter and check the housing bore for burrs or damage. Apply the same lubricant used in the equipment to the lip, then press the seal in with a tube or press that contacts only the outer edge, never the lip. If the shaft shows a wear groove, a seal with the lip in a different position may be needed. Selection also depends on speed, temperature and the fluid being sealed.

For an equivalent or a different size, provide part number 5354 or the shaft, housing and height measurements. The team can suggest alternatives and help you choose the right seal. MR Industrial Accessories supplies the DBH brand as part of its seals and oil seals line.
