DBH 9111 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 9111 and any equivalents.

The DBH 9111 is a single-lip radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With a 33 mm shaft, 45 mm housing bore and 5 mm width, it fits where axial space is limited. The seal presses into the housing and its flexible lip runs against the shaft, tolerating minor misalignment. As a wear part, it should be replaced when leaks or abnormal noise appear.

This oil seal carries the DBH brand and part number 9111. It is an Lx design: one sealing lip with a spring and no external dust lip. The elastomer lip is bonded to the metal case by vulcanization, giving both sealing performance and structural strength. Dimensions are shaft 33.00 mm, housing 45.00 mm, width 5.00 mm.

Typical installations include pumps, electric motors, gearboxes, conveyor rollers and power transmission components, as well as machine tools, compressors and hydraulic systems where oil or grease must be contained and dust or water excluded. It suits moderate peripheral speeds and temperatures within the normal range for nitrile elastomers. Its role is to protect bearings and keep the assembly running.

During installation, verify that the shaft surface is polished, free of burrs and scratches, and has suitable hardness and roughness. The housing must be clean and undamaged. Press the seal in with a flat tool that contacts the metal edge only, never the lip. Before fitting, lubricate the lip with the same oil or grease used in service. The lip must face the fluid side, and the spring must sit correctly in its groove.

For an equivalent, send part number 9111 or the dimensions 33 x 45 x 5 mm by WhatsApp. Alternatives in other brands or materials can be sourced. Also inspect the shaft: if it is worn, a seal of the same size may not seal, and a repair sleeve or an offset-lip seal may be required. Share your application details and we will advise.
