Part 8305 from DBH is a radial lip seal built to hold lubricant inside a housing and keep dust, water and other contaminants out of the bearing area. Its three key measurements are a 57 mm shaft, an 84.80 mm housing bore and a 21.00 mm overall height, and it carries the design reference A 214. MR Industrial Accessories lists this seal within its seals and oil seals range and can help you confirm it fits your equipment.

Reading the code is the quickest way to check a replacement. The 8305 identifies the DBH item, while the three figures describe where it sits: shaft 57 mm, housing 84.80 mm, height 21.00 mm. Design A 214 tells you the construction is a radial shaft seal with a sealing lip and a metal case, the common arrangement for rotating shafts that run with lubrication.

You will find this seal in gearboxes, centrifugal pumps, electric motors, reducers and other power transmission equipment. Its job on those units is twofold: no oil or grease escaping to the outside, and no dust, water or particles reaching the bearings. The 21 mm height also makes it a practical choice where the housing leaves little room along the shaft.

Installation has a direct effect on how long the seal lasts. Confirm the shaft diameter falls within the tolerance expected for a radial shaft seal, and inspect the housing bore for burrs or wear before pressing anything in. Coat the lip with lubricant, use a driver that will not cut or distort the seal, and check the shaft for play or roughness, since either can cause early failure. The lip compound you select should match the fluid being sealed and the temperature at which the unit runs.

When a direct match is not obvious, send the code 8305 or simply the three measurements of the seal you are removing. With that information, MR Industrial Accessories searches its seal line for a suitable option and can advise you if design A 214 does not suit your housing.
