Part number 5451 belongs to the DBH line of radial shaft seals. It is a lip seal that sits in the housing and works against the rotating shaft, holding lubricant in and keeping dust, water and particles out. The three figures you need to match are shaft 72 mm, housing bore 95 mm and height 13 mm, in the Lx design. MR Industrial Accessories supplies this seal as a brand.

The Lx designation describes a single lip with a spring, meant for rotating shafts that run with permanent lubrication. Gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain drive equipment are the usual places a seal of this size turns up. Machine tools, mixers and conveyors also use it, for the same reason: oil stays in the crankcase and dirt stays away from the bearing.

Selection is not only about the three dimensions. Shaft speed, operating temperature and the lubricant in use all affect how the seal performs. The lip needs lubrication from the first start-up, and if a machine has stood idle for a long period it pays to oil the contact area before running it again.

Fitting matters as much as the part. Before inserting the new seal, check the shaft for burrs or wear, and clean the housing if the bore is marked. Drive the seal in with a tube or socket of the correct diameter, applying even pressure on the outer ring. Never strike the lip.

If you are replacing a seal from another maker, send the shaft diameter, the housing diameter and the height you measured. With those three figures we can look for a match in the DBH line or suggest another option. The same applies when the old part number can no longer be read, or when shaft wear means a repair sleeve should be considered.
