Oldham coupling with aluminum bronze spacer - Set screw
Offset of angular, parallel, or axial deviation are individual allowed value, so couple reasons of axial offset appearing at same time would reduce the unit allowable value.
Suit for high wrench torque, high rotation.
In case of parallel deviation over 0.1, abrasion of the insert is direct ration to load torque, offset, and rotation numbers.
Available options for key way per inner diameter are bigger than 6mm.
Main Frame: SYS304 alloy - Spacer: Aluminum bronze, filled with Solid lubricant
