The DBH 6619 is a radial shaft seal built to keep lubricant where it belongs and keep contaminants out. It suits rotating shafts in industrial equipment where a dependable barrier is needed. The seal's dimensions are shaft 153.99 mm, housing 171.45 mm and height 12.00 mm, and it uses the Lz design. MR Industrial Accessories supplies this brand and can help you confirm the right choice.
This seal, part number 6619, comes from the DBH brand. The Lz designation means the lip is backed by a spring, so it stays in contact with the shaft as it turns. That continuous contact is what holds oil or grease in and keeps dust, water and particles out. The three key measurements are 153.99 mm for the shaft (d), 171.45 mm for the housing bore (D) and 12.00 mm for the height (h). Match those to your shaft and bore before ordering.
You will find this type of seal in gearboxes, pumps, electric motors, rollers and power transmission equipment. In those assemblies it shields bearings and gears from dirt and stops lubricant from escaping. It is common in industrial machinery, process equipment and heavy vehicles where rotating shafts need reliable sealing.
Installation is straightforward if you prepare the surfaces. The shaft and housing should be clean and free of burrs. Apply some of the same oil or grease used in the equipment to the lip before fitting. Press the seal in squarely, putting even pressure on the outer circumference rather than the lip. The spring should face the fluid side you want to retain. If the shaft is worn, a wear sleeve or a different size may be the better route.
