This item is a radial shaft seal from the DBH brand, identified with part number 1228/85. Its dimensions are: shaft diameter (d) 56 mm, housing diameter (D) 72.2 mm and height (h) 8.00/10.00 mm. The A 398 design defines the lip geometry and the case type. Manufactured with quality elastomers and metal reinforcements, it is designed to withstand the usual operating conditions in industrial machinery. MR Accesorios Industriales carries this brand as part of its line of seals and oil seals.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the oil seal fulfills the function of retaining lubricant and excluding dust, water or particles that could damage the bearings. It is also used on fan, mixer and conveyor shafts, where sealing prevents losses and premature maintenance.

To correctly select an oil seal, verify that the shaft and housing dimensions match those of the equipment. The 8.00/10.00 mm height indicates that the oil seal can be mounted in housings with depths within that range. The A 398 design may have an auxiliary lip or specific sealing characteristics; consult the manufacturer's data sheet if you need details. During assembly, lubricate the lip, avoid damaging it with sharp edges and make sure the shaft does not show excessive wear.
