The DBH 9859Vit is a radial shaft seal from the DBH line, built as a single-lip seal with a spring (Mz-R H design) for rotating shafts lubricated with oil or grease. Its three key dimensions are shaft 19 mm, housing 36 mm and height 6.60 mm. This seal keeps lubricant in and contaminants out of small gearboxes, pumps, electric motors and other power transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your shaft, housing and operating conditions.

Reading the code helps you order the correct part. The 9859Vit number identifies this item within the DBH range, while Mz-R H tells you it is a single-lip, spring-loaded seal for rotating shafts. In service, the lip rides against the shaft and the outer case presses into the housing, creating a barrier that holds oil or grease in place and blocks dust, dirt and moisture from reaching bearings and gears.

Seals in this size range show up in small gearboxes, centrifugal pumps, low-power electric motors, compressors, machine tools and belt- or chain-driven transmission equipment. You will also find them on rollers, mixers and conveying systems wherever a rotating shaft needs to be isolated from its surroundings. In each case, the seal protects the lubricant and limits the particles that speed up wear on bearings and gears.

Proper installation protects the seal and the equipment. Confirm the shaft measures 19 mm and has a smooth, polished surface without burrs or scratches. Lubricate the lip before sliding it into place, and use an installation tube that presses on the outer edge of the seal, never on the lip itself. The 6.60 mm height must match the housing depth. For high-speed operation or dirty environments, ask about designs with an auxiliary lip or a more resistant material. Always verify the working temperature and fluid before selecting.

If you need a replacement or an equivalent, send the part number 9859Vit along with the shaft, housing and height measurements. A photo of the old seal or the assembly drawing also helps. MR Industrial Accessories checks those details against the manufacturer's product page and suggests alternatives from the same brand or other lines we carry, so you avoid a seal that does not fit or cannot handle your actual operating conditions.
