Cranfield Precision's miniature air bearing spindle is only 35mm diameter and 103mm long.
Cranfield Precision has incorporated high precision air bearing technology as well as a small air turbine drive for spindle power. An additional feature of this spindle is that it also contains a linear slide, which allows for an axial stroke of several millimeters.
Initially developed for Electro-Discharge Machining, the available speed range also makes the spindle suitable for other high speed micro machining applications in a restricted space. The combination of air bearings and air turbine drive mean that the spindle is maintenance free and only requires a clear air supply for operation.
The main features of the small air bearing are:
Size - Ø35mm x 103mm long
High speed range (up to 30,000 rpm)
Only air supply is required for operation
Kinematic mount for highly repeatable on-machine location
Maintenance-free air bearings
Clean room compatible
