The DBH 5233Sil is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 75 mm shaft, a 100 mm housing bore and a 12 mm axial space, and it uses the Lz lip-and-spring design. Maintenance teams specify this seal for gearboxes, pumps, motors and similar drives. MR Industrial Accessories supplies it as part of its seals and oil seals range.

The code breaks down simply: DBH is the seal type, 5233Sil is the profile reference, and Lz tells you the lip has a spring for consistent contact on the shaft. The three numbers that matter for fit are shaft 75.00 mm, housing 100.00 mm and height 12.00 mm. The 100 mm outer diameter presses into the housing bore, the 75 mm lip rides on the shaft, and the 12 mm height sets how much axial room the cavity needs.

You will find this size in gearboxes, speed reducers, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. In each case the seal does two jobs at once: it holds oil or grease inside and it blocks dust, water and particles from reaching bearings and gears. Machine tools and continuous-process lines also use it where a rotating shaft passes through a housing.

Installation calls for a few checks. The shaft surface should be hard enough and smooth, with no burrs or scratches that could cut the lip. Coat the lip with the same lubricant used in the equipment before you seat the seal. Press it in squarely, applying force to the outer ring, not the lip. If the shaft is worn, a repair sleeve or a different size may be the better route. Speed, temperature and lubricant type all affect the final choice.

If you need a seal that matches the 5233Sil, send the part number or the three dimensions through WhatsApp. We can search our seals line for equivalents in other brands or lip configurations and help you pick the right design for the application. MR Industrial Accessories also manufactures split plummer block housings, roller chains and sheaves.
