The DBH 5163Sil is a radial shaft seal that fits on the shaft and seals against the housing bore, keeping lubricant in and keeping dust, water and particles out. With a 25 mm shaft, a 45 mm housing and a 10 mm height, it suits medium-sized equipment where axial room is tight, such as pumps, electric motors, gearboxes and transmissions that turn continuously.

This seal belongs to the DBH line and carries the reference 5163Sil. Its published figures are shaft 25 mm, housing 45 mm, height 10 mm and Lz design. Lz refers to a lip seal with a construction layout specific to the series; for details on the lip, the spring or the compound, check the manufacturer's data sheet. Use the code 5163Sil when you place your order.

Seals of this size are common on centrifugal pump shafts, electric motor shafts, gearbox shafts, rollers and transmission equipment. The job is always the same: hold oil or grease inside the assembly and stop outside contaminants from getting in. You will also find them on agricultural machinery, washing equipment and process lines where the shaft turns continuously and dust or moisture is present.

Correct mounting starts with preparation. The shaft should be clean, with no burrs or marks, and the housing should be free of deformation. Lubricate the lip before insertion and press with a tool on the outer edge, never on the lip. Choosing the right seal depends on shaft speed, operating temperature and the fluid being retained, since those factors set the lip and body material. A worn shaft can be handled with a repair sleeve.

If you need an equivalent or another size, send the code 5163Sil along with your shaft, housing and height measurements, plus the fluid and working temperature. That is enough to locate an alternative in the DBH line or in other brands MR supplies. When there is room, a seal with a slightly different height or diameter may also work, provided the housing and shaft accept it.

MR Industrial Accessories carries the DBH brand within its range of seals and oil seals, alongside bearings, power transmission components and lubricants.
