Turns per stroke 4.5 Torque 45 Nm / 33 lbf ft Weight 7,8 kg / 16,4 lbs Attachments Dimensional drawing No. 233847 Comments The VATRING patented by VAT guarantees a constant closing torque during the specified cycle life of 10'000 cycles. No service except regreasing of the spindledrive after high bakeout is necessary during this cycle time.
