The DBH 5313Sil is a radial shaft lip seal built to keep lubricant inside a housing and keep dust and moisture out where a shaft passes through. Its size callout is 25 x 42 x 8 mm, meaning a 25.00 mm shaft, a 42.00 mm housing bore and an 8.00 mm width. The Lz Sil lip configuration, the elastomer body and the internal spring work together to hold steady contact against the rotating shaft. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your fluid, shaft speed and operating temperature.

The 5313Sil belongs to the DBH line of radial shaft seals. Read the code and the numbers together: 5313Sil identifies the seal, while 25.00 mm, 42.00 mm and 8.00 mm describe shaft, housing and width in that order. Lz Sil refers to the lip design. The spring-loaded lip maintains contact on the shaft, and the elastomer compound is selected for the fluid and temperature in service. This is a drop-in replacement where that exact dimensional combination is required.

You will find this seal on gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In each case it separates oil or grease from the outside environment and shields the bearings from dust and water. Agricultural and general industrial equipment running at moderate shaft speeds in dirty or damp conditions is another common home for it. Lip material selection follows the fluid and the temperature the seal will see.

Before installation, confirm the housing bore is clean and free of burrs and that the shaft shows no scoring or wear. Coat the lip with the same oil the equipment uses, then press the seal in squarely; a seal that goes in crooked will leak early. Where the shaft has a worn track, a repair sleeve is worth considering. Peripheral speed and temperature are the two factors that most influence which lip compound fits the job.
