The Lz design indicates a lip configuration that runs on the shaft with a controlled lubricant film. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right oil seal for your application.

This item is a DBH 8145 radial shaft seal, identified by the designation 8145. Its main attributes are: shaft diameter (d) of 114.3 mm, housing diameter (D) of 139.7 mm and height (h) of 14.28 mm. The Lz design corresponds to a lip geometry with a spring that ensures constant contact against the shaft. It is made from elastomers resistant to mineral oils and greases, and its structure includes a metal reinforcement that gives it rigidity for press fitting.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment in general. It is found in industrial machinery, process plants, road and agricultural equipment. Its function is twofold: to prevent oil or grease from leaking out of the housing and to block the entry of dust, water or particles that accelerate wear on bearings and bushings.

To select an oil seal correctly, check that the shaft and housing dimensions match those of the equipment. The height must be compatible with the housing depth and the available space. The Lz design is suitable for moderate speeds and low pressures. During installation, lubricate the lip with the same oil used in the equipment, avoid striking it and make sure the shaft has no burrs or marks that could damage the seal. If the shaft shows wear, consider a nearby size or a repair sleeve.
