The DBH 1044 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 43 mm shaft, 55 mm housing and 8 mm height, and A 189 design, it is press-fitted into the housing and runs against the shaft. It is a key part in gearboxes, pumps, electric motors and transmission equipment, where it prevents leaks and protects bearings. MR Accesorios Industriales carries it as part of its line of seals and radial shaft seals.

This item is a radial shaft seal from the DBH brand, identified with the code 1044. Its dimensions are 43.00 mm shaft diameter, 55.00 mm housing diameter and 8.00 mm height. The A 189 design corresponds to a single-lip configuration with a spring, suitable for general oil or grease retention applications. The nomenclature 1044 is the manufacturer's commercial designation for this specific size and design.

Radial shaft seals such as the DBH 1044 are used in rotating equipment where the passage of the shaft through a housing must be sealed. Typical applications include gearboxes, centrifugal pumps, electric motors, compressors, mixers and conveyor rollers. They also appear in machine tools and belt- or chain-driven transmission equipment. In all cases, their function is twofold: to retain the lubricant inside the assembly and to prevent the ingress of dust, water or particles that accelerate wear on bearings and gears.

To correctly select a seal, you must verify the shaft and housing dimensions, the type of lubricant, the working temperature and the peripheral speed. Installation requires cleaning and lubricating the lip, using an installation tool that does not damage the seal and ensuring that the lip is oriented toward the lubricant side. If the shaft shows wear or grooves, a repair sleeve or an alternative size should be evaluated. Shaft runout and play also influence the service life of the seal.
