A radial shaft seal with an Mx profile, the DBH 1159 is built for rotating shafts that measure 85 mm in diameter. It fits into a 105 mm housing bore and stands 10 mm high. Its job is to hold lubricant in place while keeping dust, water and other particles out of gearboxes, pumps and similar industrial equipment. Because it is a wear part, it should be swapped out once oil starts leaking or the shaft raceway shows play or roughness.

The key figures for the DBH 1159 are shaft 85 mm, housing 105 mm and height 10.00 mm. Its Mx design means a sealing lip with a spring, which suits rotating shafts that run with lubrication. MR supplies the DBH brand, so you can order the exact designation 1159 or a dimensional equivalent. Manufacturer naming can shift from batch to batch, but the dimensions are what determine whether one seal can replace another.

You will find this type of seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission equipment, as well as in road, agricultural and process line machinery where a shaft turns inside a lubricated housing. How long it lasts depends on rotation speed, temperature, pressure and the condition of the shaft surface, so it pays to inspect it whenever the equipment is opened up.

Before installing, check the shaft for burrs or deep marks in the contact zone, since a scratched raceway will wear the lip early. Coat the lip with the same oil the equipment uses, then seat the seal squarely on the shaft without striking it unevenly. If the housing itself is damaged, look at a seal with a sleeve or a repaired seat. Your selection comes down to the d, D and h dimensions plus the elastomer and spring type.

To request a quote for code 1159, send the shaft, housing and height dimensions, or an equivalent from another brand. With that information we can search for an alternative in the same Mx design or suggest a seal with similar characteristics, and we can also help if space is tight or the equipment runs hot. A manufacturer data sheet is not required; the dimensions are enough to identify the replacement.

MR Industrial Accessories carries DBH seals along with other industry brands. To get a quote, message us on WhatsApp with code 1159 plus a photo of the old seal or caliper readings. We will come back with the option that fits your equipment.
