SMC's new MQQ series low-friction cylinders have typical applications in
semiconductor wafer polishing, coil winding and cutting operations
requiring constant force. Two models are currently available. The MQQT
has maximum and minimum operating pressures of 0.5Mpa and 0.005Mpa, and
speeds from 0.3 to 300mm/s; while the MQQL features an integral ball
bearing, which increases resistance to lateral loads, to provide tension
control under conditions of very low pressure with very small pressure
variations.
