This item is a DBH radial shaft seal, identified with part number 8143. Its dimensions are: shaft diameter (d) 165.10 mm, housing diameter (D) 203.25 mm and height (h) 25.40 mm. The Lx design indicates a configuration with a sealing lip and spring, without an external dust lip. These dimensions correspond to the manufacturer's data sheet and must be verified against the housing before installation.

Radial shaft seals are used in gearboxes, pumps, electric motors, rollers and power transmission equipment. Their main function is to retain the oil or grease inside the assembly and exclude dust, water or particles. In applications with large-diameter shafts, as in this case, they are commonly found in heavy machinery, mills, conveyor belts and industrial equipment for continuous processes.

To correctly select an oil seal, verify that the shaft and housing dimensions match those of the equipment. The height must allow assembly without interference. The Lx design is suitable for moderate peripheral speeds and low pressures. During assembly, lubricate the lip with the same working fluid, avoid damaging the sealing edge and make sure the spring is correctly positioned. Careful installation extends the service life of the seal.
