With a 105 mm shaft, 161 mm housing and 15 mm height, and Lz design, it is a replacement part for equipment with shafts of that diameter.

This item is a DBH 6685 radial shaft seal, identified by its designation 6685. Its dimensions are shaft (d) 105 mm, housing (D) 161 mm and height (h) 15.00 mm. The indicated design is Lz, which corresponds to a lip and case configuration designed for lubricant retention on rotating shafts. It is a radial type seal, not an axial seal or a static gasket: it works with relative movement between the lip and the shaft. The DBH nomenclature identifies the product brand.

It is used in equipment where a shaft rotates inside a housing and oil or grease leaks must be prevented, while at the same time keeping dirt out. It appears in gearboxes, pumps, electric motors, rollers, mixers and transmissions in general. Also in applications where the seal protects nearby bearings or bushings. If the equipment operates with vibration, temperature or exposure to dust, it is advisable to verify that the Lz design is suitable for that condition.

To fit a radial shaft seal, the shaft must be clean, free of burrs and marks, and the housing free of deformation. The lip is lubricated before inserting it and is pressed in with a flat tool to avoid damaging it. Selection depends on shaft speed, working temperature and the type of fluid. If the previous seal failed, check the condition of the shaft: wear or runout greater than tolerated shortens the life of the new seal.
