For large rotating equipment, the DBH 1158 radial shaft seal keeps lubricant in and contaminants out. It fits a 200 mm shaft, a 230 mm housing bore and a 15.00 mm height. The Lx design uses a spring-loaded single lip for shafts that run with continuous lubrication. In sizes like this, the seal protects bearings and bushings from premature wear and helps avoid unplanned downtime.

The code 1158 identifies this DBH radial shaft seal. Reading the dimensions in order: shaft 200 mm, housing 230 mm, overall height 15.00 mm. Its cross-section is thin relative to its diameter, which suits large assemblies where axial room is tight. The Lx designation points to a single lip with spring, a common choice for rotating shafts under permanent lubrication.

You will find seals in this size range in gearboxes, mills, large centrifugal pumps, mixers, rotary dryers and power transmission drives. Kiln rollers, presses and other heavy machinery also use them. The job is always the same: hold oil or grease inside the assembly and keep out dust, water and particles that speed up wear on bearings, gears and shafts.

When selecting a replacement, confirm three values: shaft diameter, housing bore and available height. The shaft surface should be ground and free of deep marks; suitable roughness and minimum hardness help the lip seat and last. At installation, coat the lip with the same oil or grease used in the equipment, press the seal in perpendicular to the shaft and avoid impacts or deformation. Remove burrs from the housing before fitting.

If you need an equivalent, send code 1158 or the dimensions 200 x 230 x 15 mm on WhatsApp. We can review options in the DBH line or other brands we carry and confirm them against the manufacturer's technical data. Before replacing, inspect the shaft and housing; heavy wear there can stop a new seal from sealing correctly.

MR Industrial Accessories supplies seals and oil seals from several brands, along with housings, chains and sheaves from our own manufacturing. For help with the DBH 1158, message us on WhatsApp with the code or dimensions and we will point you to the right part for your equipment.
