A Shaft Feather Key is used in piston pumps to connect the pump shaft to the piston. It is a small, rectangular metal piece that fits into a keyway, which is a slot or groove on the shaft and piston. The purpose of the shaft key is to transmit torque from the shaft to the piston, allowing the piston to move up and down within the pump cylinder.Attributes:• Prevents rotational slippage between the shaft and the piston• Ensuring a tight fit and proper alignmentApplications:A Shaft Feather Key transmits torque and enables the reciprocating motion necessary for pump operation.
