A radial shaft seal from the DBH line, the 8770Vit seats on a 140 mm shaft and presses into a 170 mm housing bore, with a 15.00 mm overall height. Its Lx-Bidi geometry pairs a sealing lip with a bidirectional profile, so it holds lubricant in and keeps dust, water and particles out even when the shaft reverses direction. You will find this size on gearboxes, pumps, motors and transmission equipment.

Reading the code is straightforward: 8770Vit identifies the seal, and the three values 140 x 170 x 15 mm describe shaft, housing and height in that order. The elastomeric lip rides against the shaft, while the outer diameter holds the press fit in the bore. The Lx-Bidi construction suits shafts that turn both ways or change direction during operation.

Because a 140 mm shaft is common on larger drive trains, this seal turns up in reducers, centrifugal pumps, big electric motors and belt or chain drives. It also appears on road machinery, mining equipment and process lines. In every case the job is the same: keep oil or grease where it belongs and keep contamination out.

Before ordering, confirm all three dimensions against the actual shaft and housing, and follow the maker's orientation for the Lx-Bidi lip. The shaft should be ground and lightly lubricated so the lip slides on without damage. Where vibration or temperature runs high, an alternative elastomer may be worth considering.

For a quote, send the code 8770Vit or the dimensions 140 x 170 x 15 mm by WhatsApp or email. If your housing allows it, ask about design variants such as seals with an auxiliary or double lip. The team can also suggest an equivalent and help you confirm the designation for your machine.
