The DBH 8237Pol radial shaft seal is a lip seal that closes off the passage of oil or grease in equipment with a rotating shaft. Because of its dimensions —85.70 mm shaft, 102.62 mm housing and 9.73 mm height— it is used in gearboxes, pumps and motors where lubricant must be retained and the entry of dust or water stopped. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a seal with Lx-H design: sealing lip with spring and outer metal case. The dimensions shown on the product page are 85.70 mm shaft diameter, 102.62 mm housing diameter and 9.73 mm total height. Those three dimensions are what determine whether the seal fits your equipment, so it is worth comparing them with the housing and shaft before ordering. The code 8237Pol identifies this specific size within the DBH line.

Typical applications for a seal of this size are in power transmission and rotating equipment: gearboxes, centrifugal pumps, electric motors, reducers and machine rollers. In all those cases the seal runs on a rotating shaft and against a fixed housing, retaining the lubricant and preventing it from escaping through the cover. It is also used as a barrier against dust and water when the equipment operates in a dirty environment.

To install it properly, the shaft must be clean, free of burrs or marks, and the housing free of old sealant residue. It is advisable to lubricate the lip with the same grease or oil used in the equipment before seating the seal, and to tap evenly on the outer ring, never on the lip. If the shaft is worn or has a marked groove, the new seal may not seal: in that case it is worth evaluating a wear sleeve.

To quote the code 8237Pol, send us the shaft, housing and height dimensions, plus a photo of the old seal if you have it on hand. With that data we look for the equivalent in the same brand or in another line we carry. We also confirm whether the Lx-H design is suitable for your application according to the type of lubricant and the rotation speed.
