With dimensions of 180 mm shaft, 200 mm housing and 12 mm height, and Mx design, it is used in gearboxes, pumps, electric motors and process machinery. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified by part number 8749. Its dimensions are 180 mm shaft diameter (d), 200 mm housing diameter (D) and 12.00 mm height (h). The Mx design corresponds to a configuration with a sealing lip and metal body, suitable for retaining oil or grease in rotating equipment. The lip elastomer and body material are confirmed against the manufacturer's data sheet at the time of inquiry.

Typical applications for a seal of this size include gearboxes, conveyor rollers, centrifugal pumps, large electric motors and continuous process equipment. In all cases, the seal protects the bearings and the lubricant from external contamination, and prevents leaks that could affect operation and the surrounding area. It is a wear part that should be replaced when lubricant loss or noise appears in the assembly.

To install this seal, verify that the shaft measures 180 mm and the housing 200 mm, with 12.00 mm height available. The shaft surface must be clean, free of burrs and deep marks, and it is advisable to lubricate the lip before inserting it. The Mx design faces the lip toward the lubricant side; respect that position. If the equipment runs with heavy vibration or temperature, ask us about material alternatives.
