The DBH 8293 is a radial shaft seal built for a 25 mm shaft, a 41.40 mm housing bore and a 6.00 mm height, in the Lx design. It keeps lubricant where it belongs and keeps dust, water and particles out, which is what protects bearings and bushings from premature wear. Gearboxes, pumps and electric motors are the usual places you will find it.

The code 8293 sits inside the DBH line. Reading the number tells you the three values that matter: shaft 25 mm, housing bore 41.40 mm, height 6.00 mm, plus the Lx designation. Lx describes how the lip and the metal case are shaped, so it governs how the seal sits in the bore and how evenly it rides on the shaft. When you replace the part, that designation has to match as well as the dimensions.

Seals like this one work wherever a rotating shaft separates two environments. Gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools all rely on them. Oil or grease leaking out, or contaminants working their way in, is one of the most common reasons bearings and housings fail early.

Selection comes down to three checks: shaft diameter, housing bore diameter and the height available. Lubricate the lip before you press it in, and use a driver that will not nick the sealing edge. A shaft with wear or a groove can defeat a new seal even when every dimension lines up, so in that case it is worth looking at an alternative design.

If you need a replacement for the 8293, send the part number, the shaft, bore and height measurements, and a photo or sample of the old seal. Our team works from that data to find a match in the DBH line or another brand we supply, and replies by WhatsApp or email with the quote and any equivalents.
