A radial shaft seal such as the DBH 1120 keeps lubricant where it belongs and keeps contaminants out at the point where a rotating shaft leaves a housing. This one carries the designation 1120 and the measurements 41 mm shaft, 59 mm housing and 11 mm height, with design A 248. It is a size that turns up regularly in power transmission and general industrial machinery, and MR Industrial Accessories supplies the DBH line and can help you confirm the right seal for the job.

Reading the item: DBH identifies the radial shaft seal, 1120 is the designation, and the three figures that matter are shaft diameter 41 mm, housing diameter 59 mm and height 11 mm. Design A 248 describes how the lip is built. In service, the lip rides against the rotating shaft while the outer diameter sits in the housing under interference, which is what holds the lubricant in and the dust, water and particles out.

Typical locations include gearboxes, pumps, electric motors, rollers, mixers and other power transmission equipment, as well as agricultural machinery, conveyors and process lines where a shaft turns inside a lubricated housing. Treat it as a wear part. Once the lip stiffens, tears or the spring loses tension, you start to see lubricant weeping out or contamination working its way in.

When fitting a replacement, inspect the shaft for burrs, scratches or a worn sealing surface, and make sure the housing bore is clean and free of dents. Put a little lubricant on the lip, then press the seal in squarely using a tube or spacer that bears on the outer edge so it does not cock. If the shaft already shows a pronounced groove, consider a wear sleeve before the new seal goes in.

If you are after an equivalent, send part number 1120 together with the shaft, housing and height measurements, the lubricant type and the operating temperature. With those details we can review options in the DBH line and other brands we carry and confirm which one fits without reworking the housing. We can also check against the manufacturer's data sheet whether design A 248 suits your application.

If the old seal is in front of you, send the stamped number or the readings from your caliper and we will get you a quote by WhatsApp or email. We can suggest equivalents and help you choose.
