Part 8216 from the DBH line is a radial shaft seal built for rotating shafts. It keeps oil or grease where it belongs and blocks dust, water and other particles from working their way in. Shaft 42.00 mm, housing 53.00 mm, height 8.00 mm: the seal presses into the housing bore and its flexible lip rides on the shaft. Treat it as a wear item and swap it out as soon as any weeping shows up.

The code breaks down simply. The 8216 number is the manufacturer's item designation, not the series, so it should be read on its own. The Mx configuration means one sealing lip and no secondary dust lip. Dimensions follow the usual order for this type of part: shaft 42.00 mm, housing 53.00 mm, height 8.00 mm. MR Industrial Accessories supplies this standard seal as part of its seals range.

Where you will find it: gearboxes, pumps, electric motors, transmission shafts and process equipment. The job is the same everywhere, holding lubricant in and contaminants out. Continuous shaft rotation with a small pressure difference between inside and outside is the typical condition. Machine tools, conveyors and food processing equipment also use this style of seal when the lip compound suits the fluid being sealed.

Installation comes down to fit and surface condition. Confirm the shaft and housing measurements against the dimensions above before you start. The shaft should be smooth, with no burrs, scratches or worn tracks, since roughness shortens lip life. Wipe the lip with the same oil or grease used in the unit, then drive the seal in with a tube that presses on the metal case, keeping contact away from the lip. The 8.00 mm height has to seat completely in the bore without distorting the housing. If the shaft shows a groove or shoulder, check where the lip will sit so it runs on sound metal.

For a quote, send the complete part number, the shaft, housing and height dimensions, and a photo of the old seal. That lets us check for an alternative in the DBH line or another brand we carry. Tell us too if the original had a special construction, such as a second lip or a dust lip, so the replacement matches rather than fails on a design difference. Guessing at dimensions rarely pays off: an off-size seal leaks at the lip or at the bore.
