A radial shaft seal such as the DBH 8128 keeps lubricant where it belongs and keeps contaminants out. It seats in the housing bore and rides on the rotating shaft, so the lip does the sealing work while the metal case holds the shape. The reference covers a shaft of 53.00 mm, a housing bore of 68.00 mm and a height of 10.00 mm, with design Lz: a single lip with a spring. MR supplies the DBH line, so you can order this reference directly.

Reading the number helps when you are standing at the machine. The 8128 is the designation to quote, and the three figures that matter are 53.00 mm for the shaft (d), 68.00 mm for the housing (D) and 10.00 mm for the height (h). The Lz design tells you the seal has one lip backed by a spring, which is the usual choice for a lubricated rotating shaft.

Typical locations are gearboxes, pumps, electric motors, line shafts and process equipment, plus conveyors, agricultural implements and other plant machinery. Wherever oil or grease has to stay inside and dust or water has to stay outside, a seal in good condition protects the bearings and bushings behind it. If the shaft measures 53 mm and the bore measures 68 mm, this part drops into the original position.

Before pressing a new seal in, look at the shaft for burrs, scoring or a worn track, and check that the bore is clean and free of dents. Coat the lip with the same oil or grease the equipment runs on, then seat the seal squarely so the lip is not distorted. A shaft with a deep groove may call for a repair sleeve. Speed, temperature and the fluid in use all affect selection, so confirm those details before ordering.

If you need a cross, send part number 8128 or the three dimensions you measured. Our team can locate the DBH reference or propose a compatible alternative, and we can also tell you whether a different height will fit the same housing. Send the request by WhatsApp or email and we will reply promptly.
