The DBH 9209 is a radial shaft seal built to hold lubricant in place and keep contaminants away from rotating shaft assemblies. It measures 101.80 mm at the shaft, 152.00 mm at the housing and 25.50 mm in height, dimensions that fit gearboxes, pumps and industrial motors. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

This seal carries the DBH reference and the designation 9209. Shaft 101.80 mm, housing 152.00 mm, height 25.50 mm. The A 129 design indicates a single lip with spring, made for lubricated rotating shafts. Pressed into the housing bore, its flexible lip rides against the shaft to create a dynamic seal that stops oil or grease from escaping and blocks dust, water and particles from getting in.

Seals in this size range are common on gearbox output shafts, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. In every case, the seal keeps bearings and gears protected by retaining lubricant and keeping outside contamination out. As a wear component, it needs replacement once leaks appear or the assembly starts making abnormal noise.

Correct installation starts with a clean shaft, free of burrs and marks, with the contact surface at the right hardness and roughness. Apply lubricant to the lip before fitting it, and drive the seal in with an installation tube that presses on the outer diameter, never on the lip. The 25.50 mm height has to match the housing depth; a seal that seats off-center can fail early. When in doubt, refer to the manufacturer's data sheet.

For a cross-reference to another brand, send the code 9209 or the three dimensions of the seal you are replacing — shaft, housing and height — and we will quote matching options. We can also guide you on material or design variants based on the fluid involved and the working temperature. The more you tell us about the equipment type, speed and environmental conditions, the more precise the selection will be.
