The DBH 9989 is a radial shaft seal with Lr design, which indicates a single lip configuration with spring. Its dimensions are shaft (d) 17.45 mm, housing (D) 28.50 mm and height (h) 7.00 mm. These dimensions allow mounting on shafts with a nominal diameter close to 17.45 mm, with a 28.50 mm housing. The Lr design is suitable for applications requiring effective sealing against oil or grease leaks and protection against external particles.

This type of seal is used in a wide variety of industrial equipment: electric motors, pumps, reducers, transmission boxes, conveyor rollers and agricultural machinery. Its function is critical to extending the service life of bearings and gears, as it prevents lubricant loss and the entry of contaminants that accelerate wear. It is a frequently maintained part in production plants and repair shops.

To correctly select a seal, it is essential to verify the shaft and housing dimensions, as well as the operating conditions: speed, temperature and lubricant type. The Lr design is appropriate for applications with moderate speeds and low pressures. During assembly, it is recommended to lubricate the lip, use suitable tools to avoid damaging it and ensure that the seal is perpendicular to the shaft. Incorrect assembly can cause premature leaks.
