The DBH 5172 is a radial shaft seal built to hold lubricant inside a housing and keep dust, water and grit away from the rotating shaft. Its designation 5172 covers a shaft of 32 mm, a housing bore of 55 mm and a height of 9.50 mm, in the Lz lip configuration. Maintenance teams fit this size on gearboxes, pumps, motors and other power transmission assemblies. MR Industrial Accessories supplies the brand and helps you match the seal to the equipment.

Reading the code is the fastest way to confirm a replacement. The 5172 number identifies the seal itself, while 32 x 55 x 9.50 mm describes the shaft, the housing bore and the overall height in that order. The Lz designation points to a lip with a spring, which is the usual choice for a rotating shaft running under lubrication. It belongs to the seals and oil seals group that MR Industrial Accessories distributes for industrial maintenance work.

A seal of this type sits at the point where a shaft leaves its housing. Its job is to keep oil or grease where it belongs and to stop outside contamination from reaching bearings and gears. Typical locations include gear reducers, centrifugal pumps, electric motors, conveyor rollers and similar transmission equipment. Once the lip wears or hardens, the first sign is usually a leak or a slow loss of lubricant.

Installation calls for a clean shaft and bore, free of burrs, scratches and old seal residue. Lubricate the lip before pressing the seal in, and use a proper driver so the lip is not cut or rolled. Selection depends on shaft speed, operating temperature and the fluid being sealed. If the shaft surface is worn or grooved, a seal with an extra lip is worth considering. Always measure the actual part and compare it with the data before ordering.
