DBH 9313 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 9313 and any equivalents.

The DBH 9313 is a radial shaft seal sized for a 25.00 mm shaft, a 47.00 mm housing bore and a 7.00 mm width. It keeps lubricant where it belongs and blocks dust, water and particles from reaching bearings and bushings. The outer diameter presses into the housing seat while the flexible lip runs against the rotating shaft, absorbing small alignment errors and vibration common in production equipment.

This DBH seal carries the designation 9313 and an Lx design. In the size callout, the shaft dimension is 25.00 mm, the housing dimension is 47.00 mm and the height is 7.00 mm. The lip contacts a machined shaft surface; the outside of the seal seats in the housing bore. You will find it as a replacement item in gearboxes, pumps, motors and other transmission assemblies that run with oil or grease.

Typical service includes speed reducers, centrifugal pumps, fans, mixers, conveyors, and agricultural or road equipment where rotation is continuous and lubricant is present. It also fits process machinery that needs to contain splashes or stop oil from escaping. In every case the seal acts as a dynamic barrier, and choosing the right one depends on shaft speed, operating temperature and the fluid being retained.

During installation, check that the shaft is free of burrs and splines and that the contact area is smooth. Apply lubricant to the lip before pushing the seal in, and use a driver that bears on the outer diameter, not the lip. If the housing has a chamfer, follow its angle so the seal is not cut. The 7.00 mm height fits standard cavities; if space is tight, ask about another size.
