A radial shaft seal such as the DBH 1197Pol keeps lubricant where it belongs and keeps dust, water and other contaminants out of the assembly. It fits a 28.00 mm shaft, a 47.00 mm housing bore and a 7.50 mm height, and it follows the Lx-R H design. You will find this type of seal in gearboxes, pumps, motors and transmission equipment running in continuous service.

Read the code together with the size to identify the part correctly. Shaft diameter (d) is 28 mm, housing bore (D) is 47 mm and height (h) is 7.50 mm. The Lx-R H designation describes how the lip and the outer body are built, which suits a rigid housing and a shaft that turns without stopping. This is a seal and oil seal item from DBH, a brand MR supplies. Measure the shaft and the bore before you install anything.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. The job is always the same: hold oil or grease in and keep outside contamination out. They also serve as a secondary closure in split plummer block housings and in arrangements where a shaft rotates inside a fixed casing.

Selection starts with the shaft. The sealing surface has to be clean and free of scratches or wear, because a lip cannot seal against a damaged surface. The housing bore needs the correct machining tolerance and no burrs. Lubricate the lip before you push the seal in, keep it square to the shaft, and press on the outer edge with a tube or a press, never on the lip. If the shaft shows a groove, a wear sleeve is an option to consider.

For an equivalent, the fastest route is to send the full code from the old seal or from the equipment data sheet. Shaft diameter, housing diameter and height are enough for us to search the DBH line or other brands we carry. If the original has a special design, such as a double lip or a dust guard, tell us so the replacement keeps the same level of protection.
