A spring-loaded single lip defines the DBH 5231Vit, a radial shaft seal sized for a 45.00 mm shaft, a 65.00 mm housing bore and an 8.00 mm height. Because it takes up little room along the axis, it fits gearboxes, pumps and motors where space is tight. MR Industrial Accessories supplies this seal as part of its seals line.

The designation breaks down simply: DBH is the brand, 5231Vit identifies the size, and Lx describes the lip configuration. Lx means one sealing lip with a spring, which is the usual choice for rotating shafts that run with permanent lubrication. The outer case is metal and the sealing lip is elastomer, a standard pairing for general-purpose oil seals.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, reducers and other power transmission equipment. Two jobs are done at once: lubricant stays inside, and dust, water or particles stay outside, which protects the bearing or bushing behind the seal. Fan, mixer and conveyor shafts also use it, since those areas often carry dust or moisture.

Before installing, confirm the shaft diameter sits within the tolerance recommended for radial shaft seals, and that the housing bore has the right diameter and depth. Lubricate the lip first, and make sure the shaft surface is free of burrs or marks that could cut the elastomer. Peripheral speed and operating temperature both influence how long the seal lasts, so if your values go beyond what standard elastomers handle, it is worth looking at another compound.

Need a substitute? Send the part number 5231Vit, or the shaft, housing and height measurements, through WhatsApp. We can search the DBH line or other brands we carry while keeping the mounting dimensions the same, including options with identical shaft and housing diameters but a different height, or a different lip design.

If anything about the designation, the size or the lip material is unclear, message us on WhatsApp. The more you tell us about dimensions, lubricant, temperature and speed, the more precise our recommendation will be.
