Part of the DBH seal range, the 5056Vit is a radial lip seal that sits in the housing bore and runs against the rotating shaft. It holds lubricant on the inside and keeps dust, water and particles out. Its nominal size is 22 mm on the shaft, 47 mm in the housing and 10 mm in height, in the Lx design. Pumps, motors, gearboxes and other power transmission equipment commonly use this size.

Reading the code is straightforward: 5056Vit is the item reference, and the three figures that matter for fit are the bore it presses into, the shaft it rides on and its height. Users sometimes describe the same seal as 22x47x10, listing shaft first, housing second and height last, which is the order shown in the manufacturer's data sheet. The Lx version has one lip with a spring, so it suits shafts that turn continuously and stay lubricated.

In service, the elastomeric lip contacts the shaft while the metal outer case is held by interference in the housing. Both the lip and the shaft surface matter, because this is a wear part. Once the lip stiffens or loses its elasticity, oil starts to weep past it, and the seal should be changed before the lubricant level drops far enough to damage the equipment.

Typical installations include centrifugal and gear pumps, low and medium power electric motors, gear reducers, transmission boxes, compressors, mixers, and washing or process equipment where water is present. The seal works on two fronts at once: it keeps oil or grease on the lubricated side and blocks contamination coming in from outside. It also serves as a secondary closure on bearings and bushings, protecting the lubricant there.

Fitting it correctly starts with the shaft. Check the diameter against the tolerance given by the manufacturer and look for burrs, deep scratches or wear on the contact surface. The housing should be clean and free of old sealant, and the seal goes in squarely using a press or a support tube that pushes on the outer ring, never on the lip. Lubricate the lip with the same oil or grease used in service before mounting. If the shaft already shows a pronounced groove, a slight change of position or a wear sleeve may be the better route.

If you need another design or an equivalent from a different brand, send the code 5056Vit or the dimensions 22 x 47 x 10 mm together with the application details. That is enough for us to check options within the DBH line or among the other brands we carry, confirming dimensions and design against the manufacturer's data sheet. We can also help when the old seal has no readable markings or when the shaft was ground and no longer matches the nominal size.
