The DBH 6868 oil seal is a single-lip radial seal that mounts on an 18 mm shaft and inside a 29.25 mm housing, with a height of 8.50/10.50 mm and A 277 design. Its function is to retain lubricant inside the assembly and stop the entry of dust, water or particles, protecting bearings, bushings and gears in rotating equipment. It is available from MR, with the size ready to request a quote on WhatsApp.

This DBH 6868 oil seal has an 18 mm shaft diameter, a 29.25 mm housing diameter and a height of 8.50/10.50 mm. The A 277 design corresponds to a radial lip with spring, intended for rotating shafts with permanent lubrication. The double height allows it to be seated in cavities with a shoulder or in covers that require deeper seating. It is a direct replacement part: it is identified by the code 6868 and by its three dimensions.

It is used in gearboxes, pumps, electric motors, compressors, mixers and transmission equipment where there is a shaft rotating inside a housing and oil or grease must be contained. It also appears in road, agricultural and continuous-process machinery, where the oil seal is the most economical barrier against contamination. If the equipment operates with high vibration or temperature, it is advisable to check the condition of the lip before replacing it.

To mount it, verify that the shaft is polished, free of burrs or grooves, and that the housing has no dents. Lubricate the lip with the same grease or oil as the equipment before inserting it, and seat the part straight, without striking the lip with metal tools. If the shaft shows wear, consider a seal with an offset lip. The selection depends on the type of lubricant, the speed and the working temperature.

If you need an equivalent or a different size, send the code 6868, the shaft diameter and the housing diameter, and the available height. You can also send a photo of the old seal or the housing drawing. The more precise the dimensions, the faster the quote is resolved.
