The Lz design indicates a configuration with sealing lip and spring, intended for continuous service. MR Accesorios Industriales supplies this official 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 the code 5170Pol. Its standard dimensions are: shaft diameter (d) 30 mm, housing diameter (D) 55 mm and height (h) 9.50 mm. The Lz design corresponds to a seal with sealing lip and spring, which maintains contact on the rotating shaft. These dimensions allow it to be mounted in standard housings without special machining, provided the shaft and housing tolerances comply with what is specified for radial shaft seals.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, its function is twofold: to prevent the leakage of oil or grease from the inside and to block the entry of dust, water or particles that accelerate the wear of bearings and gears. It is a critical part in the preventive maintenance of industrial machinery.

To correctly select this seal, verify that the shaft diameter is within the tolerance recommended for radial shaft seals, that the housing has the appropriate diameter and depth, and that the rotation speed and service temperature are compatible with the lip material. During assembly, lubricate the lip with the same oil as the equipment, avoid striking it and make sure the spring is on the side of the fluid to be retained. Careful installation extends the service life of the seal.
