The DBH 6734 is a radial shaft seal that keeps lubricant where it belongs and keeps contaminants out. It fits a 28 mm shaft, a 47 mm housing bore and an 8.00 mm width, and its Mz-R-H designation defines the lip geometry and body material. You will find this seal in gearboxes, pumps, motors and other rotating equipment. MR Industrial Accessories supplies this brand and helps you confirm the right seal for the job.

Dimensions to check before ordering: shaft 28 mm, housing bore 47 mm, width 8.00 mm. The single lip rides against the shaft and stays in contact through small amounts of runout or misalignment, which is what makes a radial lip seal useful on rotating shafts. The Mz-R-H code tells you how the lip is built and what the body material is.

Typical locations include gearboxes, centrifugal pumps, electric motors, compressors, mixers, and belt or chain drive assemblies. You will also see this style of seal on agricultural equipment, washing machinery and conveying systems. Its job is to hold oil or grease in and block dust, water and particles that shorten bearing and gear life.

Before pressing it in, make sure the shaft is clean and free of burrs, nicks or spiral marks, and that the sealing surface has the right finish. Put a light film of lubricant on the lip, then seat the seal square to the shaft. Never drive it in by hitting the lip directly. If the housing has a chamfer, use it to guide the seal in without rolling the lip.

Choosing the correct seal comes down to shaft speed, operating temperature and the fluid being retained. If any of those are outside the normal range, or if the Mz-R-H lip and material are not right for your equipment, tell us and we will point you toward a different lip style or compound.
