The DBH 5427Sil is a radial shaft seal that closes the gap between a rotating shaft and its housing, holding lubricant in and keeping dust, water and other contaminants out. With a 35 mm shaft, 47 mm housing bore and 7 mm height, it fits gearboxes, pumps, motors and similar transmission assemblies. MR Industrial Accessories supplies this brand and can help you confirm the right size and lip material for your equipment.

The code breaks down as follows: 5427Sil identifies the item in the DBH line, and the Lx design means a single sealing lip with a spring, made for lubricated rotating shafts. The lip rides on the shaft while the outer diameter presses into the housing bore, which is what stops leaks. Because it is a wear part, it is normally replaced once oil weeping or contaminant ingress shows up.

A seal of this size —shaft 35.00 mm, housing 47.00 mm, height 7.00 mm— is common in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. There it shields bearings and gears from dirt and keeps the lubricant where it belongs. Fan, mixer and conveyor shafts in dusty or damp areas also use it. Temperature and the fluid being retained determine which lip compound and elastomer are appropriate.

Installation calls for a shaft within tolerance and free of burrs, nicks or wear marks, plus a clean, undamaged housing. Lubricate the lip before fitting and use an installation tube that presses on the outer diameter, never on the lip itself. If the shaft is already worn, a seal with an offset lip is worth considering. Nitrile, Viton or another elastomer is selected based on operating temperature and the oil or grease involved.

To get a quote, send the code 5427Sil or the dimensions 35 x 47 x 7 mm over WhatsApp, and a photo of the old part or the housing drawing if you have one. We compare the designation against the manufacturer's data to confirm alternative sizes and materials. When the exact size is not available, we look for the combination that fits your equipment best.
