Toric seals offer lasting protection

Fourth Quarter 2007 Other technologies

Bearing Man's seals division distributes a range of toric seals to meet the high demands of drive mechanisms in industries like earthmoving, construction and materials handling.

"These robust sealing devices have been designed to offer optimum protection to equipment exposed to abrasives and corrosion, which not only cause heavy wear to the bearings of a track, but also damage support and guide rollers of caterpillar tracks, wheel hubs and axles," says Ken Steel, divisional director of Bearing Man's seals division. "Toric seals also offer lasting protection in conveyor systems, sand preparation plants, concrete and cement mixers, as well as in many applications in the mining industry."

These seals, which consist of two identical forged alloy steel rings and two rubber rings, have highly accurate dimensions with close tolerances to enable interchangeability with similar designs. While one of the two seal rings rotates, the other is stationary. O-rings, which act as springs, maintain axial sealing pressure to provide a static seal between the seal ring and housing bore. They also transmit frictional torque. A high wear resistant capacity is achieved because the unique design allows the seal faces to move continually inwards.

To ensure trouble-free operation of these seals, a lubricant - either grease or oil - is necessary. This lubricant reaches the sealing gap by capillary action and the effect of centrifugal forces when the seal is rotating. This gives sufficient lubrication and cooling effect, preventing cold welding of the seal faces. Special purpose rubber rings for operation in low or high temperatures are also available.
