A rotary shaft seal from DBH, the 5231Sil keeps lubricant where it belongs and keeps dust and water out of the housing. Left unchecked, those contaminants shorten the life of bearings and bushings. The seal measures 45 mm at the shaft, 65 mm at the housing bore and 8.00 mm in height, and it follows the Lx design. MR Industrial Accessories supplies this brand and can walk you through the selection.

Reading the code is the fastest way to confirm a match. The 5231Sil number identifies the DBH item, while the three figures follow the usual order for this type of seal: shaft diameter (d) 45 mm, housing diameter (D) 65 mm, height (h) 8.00 mm. The Lx designation tells you what you are holding: one sealing lip with a spring and no outer dust lip. That configuration suits tight axial spaces where the priority is holding oil or grease in.

You will run into this size in gearbox housings, centrifugal pumps, electric motors, drive shafts and process equipment that runs continuously. In each case the seal does the same job: it shields bearings and gears from particles and keeps the lubricant at the point of contact. The 45x65x8 mm envelope fits medium-sized machinery operating at moderate speeds with oil or grease present.

Installation decides how long the seal lasts. Check that the shaft surface is hard enough and finely finished, and that the bore is clean with no burrs. Coat the lip with the same oil or grease the equipment uses, then seat the seal square to the shaft without hitting it directly. If the shaft shows wear, an offset lip version is worth considering. Peripheral speed, temperature and the fluid being retained all belong in the selection.
