The DBH 6768 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Thanks to its dimensions of 49.20 mm shaft, 73.02 mm housing and 12.70 mm height, and its Mz design, it is used in gearboxes, pumps, electric motors and power transmission equipment that run on shafts of that diameter. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH brand oil seal, identified with part number 6768. Its dimensions are 49.20 mm shaft diameter (d), 73.02 mm housing diameter (D) and 12.70 mm height (h). The Mz design corresponds to a single-lip configuration with spring, suitable for retaining oil or grease in applications where the shaft rotates and the housing remains fixed. The lip elastomer and the metal body work together to maintain dynamic contact without leaking.

Typical applications for an oil seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain drive equipment. In all cases it seals the passage of the shaft through the housing, preventing lubricant leaks and the entry of contaminants that accelerate wear on bearings and gears. It is a frequently replaced part in industrial plants and repair shops.

For correct installation, check that the shaft and housing diameters match the values indicated, that the shaft surface is clean and free of burrs, and that the lip is not damaged when sliding it on. Lubricate the lip before installing and make sure the oil seal sits perpendicular to the shaft. If the equipment runs at high peripheral speed or elevated temperature, check the manufacturer's data sheet to confirm the lip material and spring type.
