The DBH 6857 radial shaft seal is a lip seal that mounts in the housing and seals against the shaft to retain lubricant and block the entry of dust, water or particles. With a 70 mm shaft diameter, 115 mm housing diameter and 15 mm height, it is a common size in power transmission equipment and pumps. MR Accesorios Industriales carries it as part of its seals and oil seals line, with more than 80 years of experience in the industry.

This item is a DBH brand radial shaft seal, identified by the code 6857. Its dimensions are 70 mm shaft diameter (d), 115 mm housing diameter (D) and 15.00 mm height (h). The Lx design indicates a single lip configuration with spring, intended for rotating shafts. The sealing lip runs on the shaft and the outer case is press-fitted into the housing, creating a dynamic seal that prevents oil or grease leaks and the entry of contaminants.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the seal protects bearings and gears from premature wear by keeping lubricant in place and preventing external contamination. It is a wear part that should be replaced when leaks or abnormal noises appear in the sealing area.

To select this seal correctly, verify that the shaft and housing dimensions match those indicated. The shaft surface must be ground and free of splines, with adequate hardness so as not to damage the lip. During installation, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the housing shows wear, consider using an oversized-case seal or a repair sleeve.
