The DBH 6611 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a fixed housing. Its Lx design pairs a single sealing lip with an outer metal case that presses into the housing bore. This makes it a common wear part in gearboxes, pumps, motors and other power transmission equipment.

The seal measures 135 mm at the shaft, 171.10 mm at the housing and 15.00 mm in height. The Lx construction means a single lip with a metal outer case for press fitting into a cylindrical bore. The 6611 code identifies the size within the DBH line, so quoting that number avoids mix-ups. Because it is a wear component, the lip can harden or wear over time and begin to seep oil.

You will find this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, rollers and similar transmission equipment. It separates oil or grease from the environment, stopping lubricant from escaping and dirt from reaching the bearing. It also appears in agricultural machinery and washing systems where splashing or dust is present. If the shaft runs with high eccentricity or temperatures are elevated, a different compound should be reviewed.

To confirm the DBH 6611 fits, check that the shaft diameter, housing diameter and height match the values above. The shaft should be smooth, free of burrs and tool marks, with an appropriate finish and enough hardness to avoid wearing the lip. The housing must be clean, undamaged and have a good entry chamfer. During installation, lubricate the lip with the same oil used in the equipment, use a tool that does not deform the case, and never strike the seal directly with a hammer.

When requesting an equivalent, send the 6611 part number along with your shaft, housing and height measurements. It also helps to include the equipment where it is mounted, the lubricant type and the operating temperature. With that information we can search for an alternative in the DBH line or from other brands we supply. If the original has a special feature such as a double lip or dust guard, we compare it against the manufacturer's data sheet.
