A radial shaft seal such as the DBH 9691 sits in the housing bore and rides against the turning shaft, holding lubricant in and keeping dust, water and particles out. The three figures that matter when you read the code are shaft 35 mm, housing 58.15 mm and height 12.70 mm, a combination that shows up in mid-size pumps and transmission assemblies. MR Industrial Accessories supplies this seal as part of its seals and oil seals line for plant maintenance and repair work.

The item carries the number 9691 under the DBH brand, which MR supplies. Its Mx-Bidi designation describes a main lip built for bidirectional service, so it retains lubricant whichever way the shaft turns. Ordering is normally done by the numeric code alone, since the three dimensions are already tied to it: shaft 35 mm, housing 58.15 mm, height 12.70 mm.

Seals of this type turn up in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission drives. Whatever the machine, the job is the same: hold oil or grease inside the assembly and keep contaminants out of the bearing and gear surfaces. A lip that has hardened or been nicked lets lubricant escape and dirt work its way in, which is the point where the part should be replaced.

Before fitting one, look over the shaft for burrs or deep scoring at the contact band and confirm the housing bore is clean and undistorted. Coat the lip with the same oil or grease the equipment runs on, then press the seal in square to the shaft rather than striking the face directly. Rotation speed, operating temperature and the fluid being sealed all influence which lip compound suits the application, and a machine running hot or with heavy vibration may call for a different material.

For an equivalent, send code 9691 or the dimension set 35 x 58.15 x 12.70 mm. It also helps to name the equipment, the brand of the seal you are replacing and a photo of the part. From that we can locate an alternative from the same brand or from another brand MR supplies, keeping the shaft, housing and height values unchanged.
