The DBH 5130Sil is a radial shaft lip seal that keeps lubricant in and contaminants out of rotating equipment. With a 30 mm shaft, 52 mm housing and 10 mm height, it fits medium-sized drives. Because the lip is a wear part, hardening or scoring leads to leaks and eventual bearing damage, so timely replacement matters.

This seal belongs to the DBH line and carries the code 5130Sil. The three numbers in the code map directly to its size: 30 mm shaft, 52 mm housing, 10 mm height. The Lx designation indicates a single lip with a spring, designed for rotating shafts that run with lubrication. Before installation, check that the housing bore is smooth and that the shaft surface under the lip is free of grooves.

Typical applications include gearboxes, centrifugal pumps, electric motors, mixers, and belt or chain drives. The seal also appears on fan shafts, compressors and machine tools where oil must stay separated from the surroundings. In every case its job is the same: contain the lubricant and exclude dust, water and particles. In dusty or washdown environments, this lip is the first line of defense and its condition often determines how long the bearing lasts.

Selecting a replacement involves more than matching dimensions. Shaft speed, operating temperature and lubricant type all affect performance. A lip that runs dry can harden and lose elasticity, while a shaft with axial scratches can wear the lip in a short time. During fitting, coat the lip with the same oil or grease used in the machine, press the seal in squarely, and apply force only to the outer ring, never to the lip. Remove any burrs from the housing before seating the seal.

If you need a cross-reference, send the code stamped on the old seal, the shaft, housing and height measurements, and a photo of the assembly. With that information we can check the DBH line or suggest an alternative we carry. We can also tell you whether the Lx design suits your application or if a different lip profile or case material would be better. Accurate details help us identify the right part quickly.
