The DBH 5663 is a radial shaft seal from a brand we supply, built to keep lubricant in and contaminants out of rotating equipment. Its Lx design pairs a main sealing lip with a secondary exclusion lip, which helps in dusty or dirty conditions. The seal fits a shaft of 88.89 mm, a housing of 111.12 mm and a height of 14.00 mm, so it drops into standard bores. You will find it in gearboxes, pumps, motors and general industrial machinery.

Reading the number helps when you order: 5663 identifies the seal, while the 88.89 x 111.12 x 14 mm figures give shaft, housing and height in that order. The Lx layout uses a main lip against the shaft and a second lip that blocks particles from reaching the sealing area. The outer body is elastomer, and the lip runs with controlled interference. This is the usual setup where oil or grease must stay inside and dirt must stay outside.

You will see the DBH 5663 in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the seal sits in the housing and works against the rotating shaft. It is common on machinery running in demanding environments, where dirt speeds up wear on ordinary seals.

Before fitting, check that the shaft and housing are clean and free of burrs or scratches, and confirm the dimensions match the seal. Put the same oil or grease used in the application on the lip, then press the seal in with a tool that contacts only the outer diameter, never the lip. If the shaft is worn, a wear sleeve or a different size may be the better route. Lip and elastomer choice depends on temperature and the fluid being retained.

To quote seal 5663, send the part number or your shaft and housing dimensions. MR Industrial Accessories LLC can search for alternatives within the same brand or other brands we carry, while keeping the dimensions and design type. We can also help you pick the lip design that suits your working conditions. The more you tell us about speed, temperature and fluid, the better the recommendation.
