A radial shaft seal from the DBH line, the 9566 closes the gap where a turning shaft passes through a lubricated housing. Its measurements are shaft 84 mm, housing 104 mm and height 11.00 mm, and it comes in the Lx design. MR Industrial Accessories LLC supplies this brand and can help you confirm the size before you ask for a quote.

The designation 9566 identifies the item within the DBH range, but the code alone does not confirm a fit. What matters is the three measurements: shaft, or d, at 84 mm; housing, or D, at 104 mm; and height, or h, at 11.00 mm. The Lx design means a single lip with a spring, which holds lubricant in and keeps dust out along a rotating shaft. Before ordering, measure the shaft and the housing bore with a caliper, either on the worn seal or on the equipment itself.

You will find this seal wherever a shaft turns inside a lubricated cavity: gearboxes, pumps, electric motors, conveyor rollers, mixers and machine tools. It also shows up in power transmission assemblies and in process equipment where oil has to stay contained and contaminants kept away. Treat it as a wear part. Once the lip stiffens or the shaft surface is scored, leaking starts and the seal needs to be replaced.

Installation is straightforward but not forgiving. Clean the bore and the shaft, remove burrs or splines that could nick the lip, and coat the lip with the same oil or grease the equipment runs on. Press the seal in squarely to the shaft, and never strike the lip itself. On a worn shaft, a seal with the lip seated in a different position may be the better choice. Speed, temperature and lubricant type all influence selection, not just the dimensions.

For an equivalent, send the part number 9566 together with your measured shaft and housing diameters. We then look at options within the DBH line and at other brands MR supplies, and confirm which one fits without machining the housing. We can also advise whether the Lx design suits your application or whether a different lip style is a better match.

MR Industrial Accessories LLC supplies seals and oil seals from recognized brands to customers across the United States and in several Latin American countries. If you have the part number and the two diameters, send them by WhatsApp or email and we will quote the DBH 9566 or a suitable equivalent. The more detail you include, the quicker we can respond.
