The DBH 9297 is a radial shaft seal built for a 12 mm shaft, a 36 mm housing bore and a 7.00 mm height. It keeps lubricant where it belongs and blocks dust, water and particles that would otherwise shorten the life of bearings and bushings. Installation is by press fit into the housing, with the lip running against a ground, lubricated shaft surface. Electric motors, pumps and small to medium gear reducers are the most frequent places this seal is replaced.

This seal belongs to the DBH line and carries part number 9297. Shaft 12 mm, housing bore 36 mm, height 7.00 mm. The Lx design means a single lip with spring and no external dust lip, which suits assemblies where axial room is limited. MR supplies DBH, so the part arrives under its original designation rather than as an unbranded substitute.

Seals in this size range turn up in small electric motors, centrifugal pumps, speed reducers, compressors and power transmission equipment. The job is always the same: hold the oil or grease in and keep the outside environment out, protecting the bearings or bushings nearby. Machine tools, washing equipment and irrigation systems also use them, since dust and moisture there are what cut short the life of rotating parts.

Reading the designation is straightforward. The three figures give shaft diameter first, housing bore second and height third, so 12 x 36 x 7 tells you what to measure on your equipment. The shaft needs suitable surface hardness and a fine finish so the lip seals without early wear. The housing should be clean, free of burrs and chamfered at the entry to ease pressing. Speed and operating temperature also guide the choice of lip material.

When fitting the seal, coat the lip with the same oil or grease the equipment runs, then press it in squarely until it bottoms out in the housing. Keep metal tools away from the lip and never let it run dry. A worn or grooved shaft is a candidate for a repair sleeve. For an equivalent, send part number 9297 along with your shaft and housing dimensions.
