Part number 5729 belongs to the DBH line of radial shaft seals. It keeps lubricant inside the assembly and keeps dust, water and chips out, working on a rotating shaft. Because the Kx version carries an extra exclusion lip, it holds up well where dirt is part of daily operation. Shaft 66.68 mm, housing bore 92.03 mm, height 19.05 mm.

Reading the code helps at the counter. The 5729 number identifies the size; the Kx suffix tells you the seal has a main lip running on the shaft plus an auxiliary lip facing outward. Both sit on a metal shell that presses into the housing bore. The first lip holds oil or grease in place, the second one blocks particles before they reach the sealing edge.

These seals show up in gearboxes, pumps, electric motors, line shafts and similar rotating equipment. Anywhere a shaft turns continuously and lubricant has to stay put, a seal of this type is doing the work. The Kx configuration is the practical choice for agricultural machinery, construction equipment and process lines where grit, dust or washdown water are present.

When you order, confirm three figures: shaft 66.68 mm, housing 92.03 mm, width 19.05 mm. The height also has to clear the housing depth. Check that the shaft surface is smooth, hard enough and free of grooves before fitting, since a worn shaft will shorten seal life no matter which brand you install.

Installation is straightforward if you take care. Lubricate the lip, drive the seal in squarely with a proper sleeve or driver, and never hit it directly with a hammer. A damaged lip or a cocked shell will leak from day one.
