The DBH 9858Vit is a radial shaft seal that keeps oil, grease, and contaminants from escaping where a rotating shaft passes through a housing. Its dimensions are 17.00 mm for the shaft, 36.00 mm for the housing bore, and 6.60 mm in height. The Mz-R H design defines the lip and metal case arrangement, so the seal seats correctly on the shaft and stays fixed in the housing. This compact profile suits gearboxes, pumps, electric motors, and power transmission equipment where lubricant retention and exclusion of dust or water are critical.

The 9858Vit has a fixed size envelope: shaft diameter (d) 17.00 mm, housing bore (D) 36.00 mm, and overall height (h) 6.60 mm. The Mz-R H designation tells you how the sealing lip and outer case are built, which affects both how the lip contacts the shaft and how the case holds in the housing. Because the cross-section is small, the seal fits into tight spaces without standing proud of the bore.

You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers, and other power transmission components. It also shows up in agricultural machinery, packaging lines, and process equipment where shafts turn continuously and lubricant must stay inside. In every case, the seal shields the bearing or bushing behind it and stops lubricant from migrating out.

Before installation, inspect the shaft for burrs or wear grooves in the contact zone and make sure the housing is clean and undistorted. Apply lubricant to the lip, then use a proper installation tool to avoid flipping the lip or damaging the spring. If the shaft has a deep groove, a seal with the lip in a different position may be needed. Speed, temperature, and lubricant type all influence selection.

To find an equivalent, send the part number 9858Vit along with your shaft and housing dimensions and a photo of the old seal if available. With that information we search for alternatives in the DBH line or other brands we carry. We can also advise whether the Mz-R H design suits your application or if another variant would work better.
