MR Accesorios Industriales supplies this official brand and advises you so you choose the correct oil seal for your application.

This item is a radial shaft seal from the DBH brand, designation 1138. Its dimensions are 32.00 mm shaft diameter (d), 42.00 mm housing diameter (D) and 4.00 mm height (h). The Lt design indicates a specific construction configuration of the lip and the metal body. It is designed to be press-fitted into the housing and seal against the rotating shaft, with the lip facing the fluid to be retained. It is a common replacement part in industrial maintenance.

Typical applications include centrifugal pumps, electric motors, gearboxes, compressors, fans and transmission equipment. In all cases, the oil seal protects bearings and gears from external contamination and prevents oil or grease leaks. It is also used in machine tools, conveyors and agricultural equipment. Its compact size makes it suitable for housings with little radial space, where reliable sealing is required at moderate speeds.

To correctly select this oil seal, verify that the shaft and housing dimensions match those of the equipment. The shaft surface must be ground and have adequate hardness to prevent premature lip wear. The housing must have the correct diameter and depth, with an entry chamfer so the lip is not damaged during installation. Lubricate the lip before installing and make sure the oil seal enters perpendicular to the shaft. If the shaft shows a groove or wear, consider an alternative size or a repair sleeve.
