The DBH 5279Sil is a radial shaft seal from the DBH line, built to keep lubricant contained and contaminants out of rotating equipment. Its dimensions are 65.00 mm shaft diameter, 90.00 mm housing bore and 10.00 mm height, and it uses the Lz design. MR Industrial Accessories supplies this brand and can help you confirm it fits your application.

The code 5279Sil identifies this seal within the DBH catalog. The Lz designation indicates a sealing lip with a spring, which is intended for rotating shafts that run with lubrication. The three key measurements—65.00 mm for the shaft, 90.00 mm for the housing bore, and 10.00 mm for the height—are the ones to check before ordering. This seal is a common replacement item in industrial maintenance.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, and power transmission equipment. Its job is to hold oil or grease inside the assembly while blocking dust, water, and particles that could harm bearings and gears. The 65 x 90 x 10 mm size is typical for medium-sized machinery where dependable, straightforward sealing is needed.

Proper installation matters: inspect the shaft for burrs or splines that might damage the lip, apply the same oil used in the equipment to lubricate the lip, and use a tool that presses on the outer diameter without distorting the seal. When selecting a seal, consider shaft speed, operating temperature, and the fluid being sealed. The Lz design works for applications with moderate pressure and peripheral speeds within the usual ranges for radial shaft seals.
