The DBH 9334 is a radial shaft seal built for rotating shafts. It fits a 12 mm shaft, a 17 mm housing bore and a 5 mm height. Installed by press fit, the seal holds lubricant in place and keeps dust, water and particles out of the assembly, which is what protects the bearing and the shaft from premature wear in pumps, motors and power transmission equipment.

The 9334 belongs to the DBH line and uses an Ls design: one sealing lip plus a stainless steel spring that keeps steady pressure against the shaft. Shaft diameter is 12 mm, housing diameter is 17 mm and height is 5.00 mm. The outer body is elastomer, made for press fitting into a machined bore. The number 9334 is the size reference within the line, so it is the code to quote and the code that brings back the same item.

Typical installations include gearboxes, centrifugal pumps, electric motors, compressors, conveyors, machine tools and hydraulic systems, wherever a rotating shaft needs oil or grease contained. Treat it as a wear part: with service the lip stiffens or picks up marks, and leakage starts. Swapping it before that point keeps lubricant where it belongs and stops contamination from spreading through the assembly.

Matching the seal to the application comes down to three measurements. The shaft must meet the 12 mm dimension, the bore must meet 17 mm and the height must be 5.00 mm, the same values as the 9334. Inspect the shaft first: burrs, scoring or a rough contact band will shorten lip life, so clean and smooth that area before anything goes back together.

During installation, coat the lip with the oil or grease the equipment already uses, keep the seal square to the shaft and drive it in by tapping the outer ring only, never the lip. Clear any burrs from the housing bore beforehand. If you are cross-referencing another brand, send the 9334 code or the 12x17x5 mm dimensions and we will check our seal range. We can also review worn shaft or housing conditions and suggest whether a different size makes more sense.
