The DBH 9661 is a radial shaft seal that fits on a 12 mm shaft and presses into a 20 mm housing bore. It keeps oil or grease in and keeps dust, water and other particles out. The 9/11 mm height range gives some flexibility when the cavity depth varies slightly. MR Industrial Accessories supplies this brand and can help you verify the size before you order.

This seal uses the A 276 profile. The dimensions are shaft 12 mm, housing 20 mm and height 9.00/11.00 mm. Because the height can be anywhere from 9 to 11 mm, the same seal can sit in cavities of slightly different depths without losing its sealing function. The lip rotates with the shaft while the outer case stays fixed in the housing. Always check these numbers against your drawing or the old part before ordering.

You will find seals in this size range on small electric motors, gearboxes, water pumps, fans, pneumatic tools and light transmission equipment. They also show up on agricultural machinery, washing equipment and irrigation systems where small shafts turn at moderate speed. In every case the job is the same: hold the lubricant inside and keep contaminants outside.

When choosing a seal, look at more than the three dimensions. Shaft speed, operating temperature and the lubricant being used all affect how well the seal performs. The A 276 design is a standard single-lip profile with a spring, and it works best on shafts with a good surface finish. If the shaft is scored or has play, the lip cannot seal properly, so inspect both the shaft and the housing before installation.
