RPMC Series Gripper is a miniature pneumatic parallel gripper with excellent parallelism and accuracy between the gripper mounting surface and jaw surface. Jaws are front mounted and are supported with 'Dual-V" roller bearings to provide low friction motion and are preloaded for maximum support and zero side play. RPMC Pneumatic Grippers are top mounted and have air ports on the side or top for manifold mounting to keep the air line away from the grip area. These grippers are available in stroke lengths from 3.2 to 6.3mm (0.13 to 0.25") with a gripper force of 36 N (8 lbs).
RPMC Grippers are Clean Room and Harsh Environment rated with a corrosion resistant shield to protect the drive and bearing mechanism from chips and other contaminants. All internal components are lubricated with clean room grade lubricant and the scavenger port can be used with vacuum to prevent escapement of particulate. It can also be used with pressure to repel particulate away from the gripper jaws. This pneumatic gripper is designed for class 10 clean room, FDA, and medical applications.
Pneumatic linear motion components are double acting air cylinders that require a dry air supply with filtering to 40 microns or better. For best control of pneumatic components, flow control valves (regulating out) should be installed to regulate the speed of the device.
