Also consider
Omnitrack Heavy Duty spring loaded units are ideal where uneven track conditions or shock loading occurs. Internal springs offer full retraction of the ball within the housing. We can tailor spring pre-loads, deflections & characteristics to your requirements. Consider alternative material upgrade options to withstand severe operating environments.
Omnitrack 97 series spring loaded ball transfer units are pre-stressed for omnidirectional & accurate positioning. As these units are from our ‘heavy duty’ range they offer the lowest coefficient of friction & smoothest performance available.
When incorporating Omnitrack 97 series units into heavy press tooling or dies, the tooling can be precisely positioned & then clamped. The additional force will cause the disc springs to deflect whilst clamped, yet once unclamped, raise the tooling ready to be maneuvered away with ease & accuracy.
Material upgrade options are shown below – order by adding the suffix to the part number required, for example, 9740 ‘A’ which includes stainless steel balls & improved resistance to high temperatures.
Spring mechanism parts remain carbon spring steel irrespective of material upgrades – consult us is other materials are required.
- Maximum shock protection – Ball retracts fully within housing.
- Ideal where load balancing or unequal track/load conditions exist.
- Exceptional shock & high/low temperature resistance.
- Maximum load capacity at any angle of orientation.
- Robust integral base mounting flange complete with 2 or 3 fixing holes.
