The DBH 5559 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its dimensions are 79.38 mm for the shaft, 115.85 mm for the housing bore and 30.16 mm for the width, with an A 089 lip and case configuration. MR Industrial Accessories supplies this brand and helps you confirm the right seal for your application.
Read the dimensions in the order they are usually checked on a drawing: shaft 79.38 mm, housing 115.85 mm, width 30.16 mm. The A 089 design defines how the lip and outer case are arranged, which is what allows the seal to work on a rotating shaft. Elastomer sealing elements and metal reinforcement make up the construction, giving the seal its wear and temperature resistance.
You will find this seal in gearboxes, pumps, electric motors, transmission shafts and continuous process lines. Its job is to stop oil or grease from escaping and to block dust, water and particles from getting in, which protects bearings and gears. Industries such as food processing, chemical, petrochemical and general manufacturing rely on this type of seal to avoid unplanned downtime.
Correct installation starts with matching the shaft and housing diameters to the values above. The shaft surface should be free of burrs, with suitable roughness and hardness to avoid early lip wear. Lubricate the lip before fitting and press the seal in with a tool that applies even force so the lip is not damaged. For high-speed or high-temperature service, contact MR to review whether another design is a better fit.
