The DBH 8237Pol radial shaft seal is a lip seal that blocks the passage of oil or grease in equipment with a rotating shaft. Due to 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 dust or water ingress stopped. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a seal with an Lx-H design: a sealing lip with spring and an outer metal case. The dimensions listed on the product page are 85.70 mm shaft diameter, 102.62 mm housing diameter and 9.73 mm overall height. These three dimensions determine whether the seal fits your equipment, so it is advisable to compare 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 these cases the seal works 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.

For proper installation, 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 a wear sleeve or a nearby size should be evaluated.

If you cannot find the code 8237Pol or need a nearby size, 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 can also verify whether the Lx-H design is suitable for your application based on the type of lubricant and rotation speed.
