The DBH 1176 is a radial shaft seal built to the A 378 design. It seats in a housing bore of 52 mm with a 7.00 mm height, and its job is to hold lubricant in place while keeping dust and moisture out of rotating assemblies. MR Industrial Accessories LLC supplies this reference to plants and maintenance teams across the United States and Latin America. Because the shaft value on the product page reads 0 mm, that dimension has to be measured on your equipment before you order.

Reading the code and dimensions: the item is identified as DBH 1176, designation 1176, design A 378. On the data sheet, D (housing) is 52 mm and h (height) is 7.00 mm, while d (shaft) shows 0 mm, a placeholder that gets filled in once the real shaft diameter is confirmed. Take a caliper to the shaft or to the seal you are pulling out, and you close the gap that would otherwise cause a wrong fit at assembly.

Where these seals work: gearboxes, pumps, electric motors, rollers, and chain or belt drives, plus process equipment where oil or grease has to stay contained and water or dust has to stay out. As a wear part, it earns attention whenever leaks show up or a bearing starts making noise. Tell us where the seal sits and we can talk through the application with you.

Selection points: shaft diameter, housing diameter and width all drive the choice. Design A 378 describes the lip profile and case style, but it does not stand in for measuring the hardware. A worn shaft may call for a repair sleeve or a different size. Wipe the housing clean and use a proper installation tool so the lip does not get nicked on the way in.

For an equivalent, send code 1176 along with the dimensions marked on your equipment. We can look across the brands and series we supply, keeping shaft, housing and height consistent, and we can point you to the same A 378 design in another shaft diameter. The more detail you provide, the quicker we can answer. Technical questions come to us over WhatsApp.
