The DBH 9933Vit is a radial shaft seal built to keep lubricant inside rotating equipment and keep dust and moisture out. It measures 46 mm at the shaft, 58 mm at the housing bore and 7 mm in height, and it fits gearboxes, pumps, motors and other power transmission assemblies. MR Industrial Accessories supplies this brand and helps you match the seal to your lubricant, speed and operating conditions.

The designation breaks down into the DBH line, the reference 9933Vit, and an Lx-R H construction: a sealing lip on a reinforced body. Inside, an elastomer lip works with a spring to stay in contact with the shaft and absorb minor misalignment. The published dimensions are shaft 46.00 mm, housing 58.00 mm and height 7.00 mm.

Seals in this size range turn up in gear reducers, centrifugal pumps, electric motors, rolls and power transmission drives. Plant maintenance crews also find them on process lines, conveyors and farm equipment. Replacement is common once the original lip hardens, cracks or starts weeping oil at the shaft or bore.

Before fitting a new seal, confirm the shaft is free of burrs and deep grooves and that the bore is clean with no leftovers from the old seal. Coat the lip with the same oil or grease the equipment runs on, then press it in squarely without striking the lip. Peripheral speed, temperature and fluid type all affect the choice; a worn shaft may call for an undersize seal or a sleeve.

For an equivalent, send the reference 9933Vit or the three dimensions together with the equipment type. We compare the designation against the manufacturer's data and review other options in the same seal category. If your shaft or bore sits outside standard tolerances, tell us and we can point you toward a workable alternative.
