The DBH 9958/85 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 33 mm shaft, a 46 mm housing bore and a 12 mm width, and follows the A 357 design. The sealing lip works with a metal case that holds the seal firmly in a cylindrical housing, so it stays in place through continuous operation. This makes it a practical replacement part for gearboxes, pumps, motors and similar transmission equipment.

In the part number, the dimensions come first for a reason: shaft 33 mm, housing 46 mm, width 12.00 mm. The A 357 designation describes a single lip with a spring, the common configuration for rotating shafts. The elastomer resists oils and greases, while the metal outer case provides the interference fit the housing needs. Together they limit lubricant loss and block dust, water and particles from reaching bearings and gears.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. Agricultural machinery, conveyors and hydraulic systems also use it where a 33 mm shaft needs dependable sealing. Its compact envelope and A 357 design suit equipment with limited radial space that still requires a solid barrier against outside contamination.

Before installation, confirm the shaft surface is polished and free of burrs, and hard enough to avoid early lip wear. The housing should be clean and undamaged, with a chamfer at the entry so the lip is not cut as it goes in. Coat the lip with the same oil the equipment uses, then seat the seal perpendicular to the shaft. If shaft play is excessive in either direction, plan on replacing the related bearings at the same time.
