The DBH 1136 radial shaft seal is a lip seal that blocks the passage of oil or grease on rotating shafts and prevents dust and water from entering the bearing. It is used in gearboxes, pumps, electric motors and power transmission equipment. Its dimensions of 49 mm shaft, 68 mm housing and 8 mm height place it in the mid-range of the series. MR Accesorios Industriales carries this brand and advises you on choosing the right seal.

This item is a DBH 1136 radial shaft seal with the following dimensions: shaft diameter 49 mm, housing diameter 68 mm and height 8.00 mm. The Lx-R H design indicates a single-lip configuration with spring, suitable for retaining lubricant in one direction. The elastomeric lip runs on the shaft and the metal case is press-fitted into the housing. It is a wear component that should be replaced when lubricant leakage or contaminant ingress appears.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. It is also found in machine tools, conveyors and agro-industrial equipment where rotating shafts must be isolated from the environment. In all cases, the seal protects the lubricant and extends the life of the adjacent bearing or bushing. If the equipment operates with a lot of dirt or water, it is advisable to verify that the lip design is suitable.

To install this seal, check that the shaft has the indicated dimension and a surface free of scratches or burrs; a micro-scratch on the sealing track accelerates leakage. Lubricate the lip before inserting it and install the seal with a support tube that presses on the case, never on the lip. The housing must be clean and free of burrs. If the shaft shows wear, consider a repair sleeve or a nearby size. Selection depends on speed, temperature and the fluid to be retained.
