When a rotating shaft needs oil or grease kept in and dust or water kept out, the DBH 6868 oil seal is the barrier that does the job. It fits an 18 mm shaft and a 29.25 mm housing bore, measures 8.50/10.50 mm in height and follows the A 277 design. MR supplies this seal, and a quote is one message away.

Reading the code is the simplest way to confirm you have the right part. The number 6868 identifies the seal, and the three figures that follow describe the fit: shaft 18 mm, housing bore 29.25 mm, height 8.50/10.50 mm. The A 277 design means a radial lip with a spring, built for shafts that turn continuously with permanent lubrication. Because the height is given as two values, the seal can sit in a cavity with a shoulder or in a cover where deeper seating is needed.

Typical installations include gearboxes, pumps, electric motors, compressors, mixers and other transmission equipment where a shaft rotates inside a housing and lubricant has to stay contained. The same seal shows up in road machinery, agricultural implements and continuous-process lines, where it acts as the least costly defense against contamination. On equipment that runs with heavy vibration or high temperature, inspect the lip before you decide to replace the seal.

Installation comes down to preparation. The shaft should be polished, with no burrs or grooves, and the housing bore free of dents. Coat the lip with the same oil or grease used in the equipment, then press the seal in straight, without hitting the lip with metal tools. A shaft that already shows wear may call for a seal with an offset lip. Lubricant type, speed and operating temperature all influence the final choice.

If you need an equivalent or another size, send the code 6868 along with the shaft diameter, the housing diameter and the height you have room for. A photo of the old seal or the housing drawing also helps. The more precise the dimensions you provide, the faster the quote is resolved.
