The DBH 9240 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its small footprint suits compact assemblies where space is limited. MR Industrial Accessories supplies this brand and helps you match the right seal to your application.

This seal carries the designation 9240 and the A 142 design, which defines the lip and metal case geometry. Its dimensions are shaft 5.5 mm, housing 16 mm and height 8.00 mm. The lip runs against the rotating shaft while the outer case sits in the housing bore, sealing the gap. An elastomer body bonded to a metal reinforcement handles continuous friction.

Typical uses include small motors, pumps, gearboxes, power tools, transmission components and precision instruments. It also appears in low-power mechanisms with moderate shaft speeds and tight cavities, such as laboratory equipment and automated devices that need dependable sealing in minimal space. The seal retains oil or grease and blocks dust, water and particles.

Before installation, confirm that the shaft and housing are clean and free of burrs or scratches. Apply the same oil or grease used in service to the lip, then slide the seal on without twisting it, making sure the spring stays in place. The shaft surface should have the correct roughness and show no wear. When selecting a replacement, account for speed, temperature and the fluid being sealed. If the original part has a different code, compare dimensions and lip style first.

For an equivalent, send code 9240 or the dimensions of your current seal. We can search for alternatives in the same radial seal category, keeping shaft, housing and height the same. We also help you choose a lip design that suits your lubricant and operating conditions. The more details you provide, the more accurate our proposal will be.
