The DBH 5349 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. It is installed in cylindrical housings and runs on the shaft with a flexible lip that maintains dynamic contact. Its dimensions of 50.80 mm shaft, 69.88 mm housing and 12.70 mm height make it suitable for industrial equipment where a reliable and easily replaceable seal is required. It is a wear part that should be checked at every maintenance interval.

This item is a radial shaft seal from the DBH brand, identified with part number 5349. Its dimensions are 50.80 mm shaft diameter (d), 69.88 mm housing diameter (D) and 12.70 mm height (h). The Lz design corresponds to a single-lip configuration with a spring, suitable for rotating shafts with lubrication. The elastomer and internal spring ensure sealing in both directions depending on the installation. It is a standard part within the DBH seal line that MR carries as an official brand.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal prevents oil or grease leaks and blocks the entry of dust, water or particles. It is commonly found on shafts with a diameter close to 50 mm rotating at moderate speeds. It is also used in agricultural and road machinery, where exposure to the weather demands robust sealing and scheduled replacement.

To correctly select a seal, verify that the shaft and housing dimensions match those of your equipment's housing and shaft. The height must be compatible with the housing depth. The Lz design indicates a lip with a spring that runs on the shaft; make sure the shaft surface is ground and free of splines. During installation, lubricate the lip with the same oil used in the equipment and use an installation tube to avoid damaging it. Avoid striking the seal and verify concentricity.
