The DBH 5240 is a radial shaft seal sized for a 36 mm shaft, a 68 mm housing bore and a 10 mm width, built in the Lz configuration. It keeps lubricant in and contaminants out of gearboxes, pumps, motors and similar rotating equipment. MR Industrial Accessories supplies it within its seals and oil seals range.

The designation 5240 identifies this DBH seal, and the Lz code describes its construction: a sealing lip backed by a spring that maintains steady contact against the shaft. The three figures to check before ordering are shaft 36.00 mm, housing 68.00 mm and width 10.00 mm. Its narrow cross-section suits machined bores where space is limited and the seal must run against a rotating shaft.

Typical installations include gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools, as well as agricultural and general industrial drives running at moderate speeds and normal temperatures. In each case the seal holds oil or grease in place while blocking dust, water and particles, which protects the bearings and keeps the assembly running.

Correct installation starts with a clean shaft, free of burrs and marks, and a housing bore at the right diameter and depth. Lubricate the lip before pressing the seal in, and keep it square to the shaft rather than driving it in at an angle or striking the lip. Where the shaft shows wear, an offset lip or a repair sleeve is worth considering. Speed, pressure and lubricant type all influence selection, so ask if anything is unclear.

To quote part 5240, or to match a seal you already use, send the shaft diameter, housing diameter and height. A brand reference or the equipment it fits also works, and an exact part number is not required. From that information we review options in the same category and come back with a proposal.

This DBH oil seal is part of the MR Industrial Accessories seals catalog. Message us on WhatsApp with part number 5240 and we will respond with the relevant information. We can also help with installation or selection if you tell us which equipment the seal is installed in.
