The DBH 1158 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 200 mm shaft diameter, 230 mm housing diameter and 15 mm height place it in large-scale equipment, where reliable sealing prevents downtime and premature wear of bearings and bushings.

This item is a DBH radial shaft seal identified with the designation 1158. According to the product page data, it corresponds to a shaft diameter (d) of 200 mm, a housing diameter (D) of 230 mm and an overall height (h) of 15.00 mm. The Lx design indicates a single lip configuration with spring, intended for rotating shafts with permanent lubrication. It is a thin-section part relative to its diameter, typical of large equipment where axial space is limited.

Seals of this size are used in gearboxes, mills, large centrifugal pumps, mixers, rotary dryers and power transmission equipment. They also appear in kiln rollers, presses and heavy machinery. In all cases they perform the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear of bearings, gears and shafts.

To correctly select a seal, verify the shaft diameter, housing diameter and available height. The shaft surface must be ground and free of deep marks; adequate roughness and minimum shaft hardness help the lip seal well and last. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid hitting or deforming it. If the housing has burrs, clean it before installation.
