A radial shaft seal from the DBH line, the 9942/85 keeps oil or grease where it belongs on a turning shaft while blocking dust and water from getting in. Its three key measurements are a 26 mm shaft, a 37 mm housing bore and a 10.50 mm height. Gearboxes, pumps, electric motors and power transmission equipment are the usual places you will find it. MR Industrial Accessories supplies this brand and can help you verify the size before you ask for a quote.

The reference 9942/85 covers a seal built to design A 349. Reading the number is straightforward: 9942/85 is the size identifier inside the DBH range, and A 349 tells you how the lip and the body are shaped. In service, the metal case sits in the housing bore while the lip rides against the shaft. It is a general-purpose seal intended for rotating shafts that run with oil or grease lubrication.

Typical applications include gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers and machine tools. You will also see it on gear reducers and bearing housings, where its job is to keep dust and moisture away from the bearings. Treat it as a wear part. Once the lip stiffens or the shaft shows scoring, replacing the seal is what stops lubricant from escaping.

Installation calls for a clean shaft with no burrs or splines, and a light film of lubricant on the lip before it goes in. Press the seal in square to the housing, applying force through a tube or press on the metal edge rather than the lip. On a worn shaft, a seal with an auxiliary lip is worth considering. Speed, temperature and the lubricant in use all affect the choice, so share those details and we will go through them with you.

For an equivalent, send the part number 9942/85 or the three current measurements by WhatsApp, and a photo of the old seal or the housing helps as well. We cross-reference the designation against the available options and confirm which one fits. Where the space allows, a seal with a different height or a comparable design from another line can also be reviewed.
