The DBH 5545 is a radial shaft seal built to the Lz configuration, which combines a sealing lip with a metal case. It sits between a rotating shaft and its housing to hold lubricant in and keep dust, water and other particles out. The bore is 88 mm, the housing seat is 120.62 mm and the overall width is 13.00 mm, so it suits equipment where axial room is tight but a dependable closure is still required.

MR Industrial Accessories supplies this brand and helps buyers match the correct seal to their application. The 5545 designation identifies the size; the Lz code describes the lip and reinforcement arrangement. The lip elastomer rides on the shaft, while the outer diameter presses into the housing to stop leakage. Because it is a wear part, a lip that hardens or shows marks will begin to pass oil.

Seals in this size range turn up in gearboxes, pumps, electric motors, transmission shafts and process machinery. They are also common on older or imported equipment where the housing was originally dimensioned in inches and converted to millimeters, as with the 120.62 mm seat here. In food, paper and chemical plants the seal works both ways: it keeps lubricant in and keeps product or wash water out of the bearing. On equipment with high vibration or temperature, inspect the shaft surface before replacing.

Installation calls for a clean shaft free of burrs or splines that could nick the lip. Coat the lip with the same grease or oil used in the equipment, and confirm the housing bore is undamaged. The 13.00 mm width has to match the housing depth; a seal that sits out of plane will not seal properly. When selecting a replacement, hold to the shaft and housing diameters first. The Lz design can differ between makers, but dimensions are the starting point. A worn shaft may call for a repair sleeve.

For a seal equivalent to the 5545, send the complete code, the shaft and housing dimensions, and a photo of the old part. The team compares that information against the manufacturer's data sheet and suggests an alternative that does the job. They can also confirm whether the Lz design interchanges with other lip configurations. The more detail you provide, the faster the right option is found. Quotes are requested by part number through WhatsApp or email, and the team replies promptly.
