This testing device comes in the form of pusher and receiver cups to support the bearing while being pressure loaded during test. This style of tool is designed to work with a press (hydraulic/ pneumatic) and customer own load cell.

Press style proof loading tools are ideal for any specification where precise incremental loads need to be applied as they securely hold the bearing and evenly distribute the load to provide accurate testing results. Each size of bearing requires its own pusher and receiver cup in order to accurately match the swaging groove and housing on each bearing.


Breakaway torque testing tool takes the form of a specialized torque wrench which, while holding the bearing in place, measures the force required to rotate the inner race once the bearing is installed in its housing.

Due to the simple and lightweight design Aero Staking break away torque testing tools can be easily used on components already installed in application. The Torque Testing Tools are simple to use and feature a memory dial indicator which records the peak force value.

Aero Staking Break Away Torque testers and receiver cups are made-to-order devices that are designed to help measure effectiveness against the requirements of the customer specification. Typical, standard tools work within a range 5-170in/lbs. but if requirement falls outside of limits a tool can be made to suit. Similarly, the hardware which fits the bearing can be adapted and customized to suit complex housings. Multiple retainers and receiver cups can be used with a single Torque Tool, this helps keeping the overall cost of a complete toolset low.


Aero Staking portable proof loader is designed as mechatronic testing device. It consists of threaded draw rod with a load cell and nut on one end and receiver cup on the other.

All hardware in conjunction with linear indicator and electronic handheld display are highly mobile units that enable, if required, proof loading of newly installed bearings without the need of removing the component from its assembly. Each unit is supplied with a load cell specific to the bearing being used and calibrated to the appropriate load value required as per specification. Electronic handheld displays can be calibrated to work with a number of load cells which reduce cost as a single display can be returned for recalibration and additional load cells added to its library only requiring the purchase of an additional cell.
