The DBH 9773 is a single-lip radial oil seal built to design A 302. It keeps lubricant in and contaminants out where a rotating shaft passes through a housing. Shaft diameter is 65.50 mm, housing bore is 100.25 mm, and the height is 13.30/22.30 mm. You will find it on gearboxes, pumps, electric motors and other power transmission equipment running with oil or grease.

The numbers to check before ordering are shaft 65.50 mm, housing 100.25 mm and height 13.30/22.30 mm. Design A 302 means a radial shaft seal with a sealing lip and a metal case, made to be press-fitted into the housing. The two height values point to a stepped profile, or a section that can take a spring or a secondary lip, depending on how the manufacturer builds it. This is a size that a standard catalog seal will not always cover, so confirm the housing geometry before you accept a substitute.

You will typically find this seal on gearboxes, centrifugal pumps, electric motors, compressors and power transmission units where the shaft turns on bearings and oil or grease is present. Agricultural machinery, process equipment and hydraulic systems also use it to hold lubricant in the sump and keep dust or water away from the bearing. In every case the seal runs against a ground shaft surface and a machined housing held to the correct tolerance.

During installation, check that the shaft diameter falls within the tolerance recommended for radial seals and that the contact surface is free of grooves or wear. The housing should be clean, with no burrs, and have an entry chamfer so the lip is not cut as it goes in. Coat the lip with the same oil or grease the equipment uses, then press it in squarely until it bottoms out. If the shaft is worn, look at a seal with an offset lip or a repair sleeve.

When you need an equivalent, send part number 9773 with the shaft, housing and height dimensions, plus a photo of the original part. With that we can check alternatives in other brands or confirm whether a standard size will work. We can also advise on lip type, elastomer material and operating temperature so the choice is right. Sizes are not always interchangeable, and verifying first avoids unplanned downtime.
