The DBH 1146 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing, while at the same time preventing the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where lubricant must be retained at a specific point. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is identified by the designation 1146 and corresponds to a shaft seal with a 124 mm inner diameter, a 152.40 mm housing outer diameter and a 27.00 mm height. The stated design is A 108, which defines the geometry of the lip and the metal body. These are the only dimensions published for this part number: any other dimension is confirmed against the manufacturer's data sheet before the order is assembled.

Typical applications for a seal of this size are in equipment with large-section shafts: gear reducers and gearboxes, centrifugal pumps, mills, mixers, conveyors and continuous-process machines. It also appears in medium-power electric motors and in heavy machinery rollers, where the seal protects the bearing and keeps lubrication inside the assembly.

To select the right seal, check that the shaft and housing diameters match the values in the table, that the cavity height can accommodate the 27.00 mm, and that the shaft surface is sound, with no burrs or wear marks. The lip must be lubricated and fitted with the correct side facing the fluid to be retained. If the shaft has play or roughness, the seal will not seal even if the size is correct.

If you need an equivalent or a nearby size, send us the part number 1146 together with the shaft and housing diameters you have on the machine. With that data we look for alternatives within the DBH line or from other brands we carry, and we confirm which option fits without modifying the housing. We can also review design A 108 against other lip variants.
