What's Included: Loading Bench and hardw Accessories sold separately: Mountz torque analyzer, BMX torque sensor and cable for
ware for mounting the BMX torque sensor. Mountz torque analyzer, BMX torque sensor and cable for BMX torque sensor. BMX torque sensor.
Reaction Position Horizontally: 4” to 28” from the center of the turn Vertically: 1” to 4” from the turn-table base Full rotation: Ratio (1:360) Horizontally: 4” to 28” from the center of the turn-table
Mounting the LB250F The LB250F needs to be mounted securely before operating. Immobilizing the loading bench is critical for the safety of the operator as well as for the accuracy of torque measurements during operation. A loo impact the validity of torque readings. Use 3/8” bolts (the bolt length will depend on your bench top thickness). securely before operating. Immobilizing the the operator as well as for the accuracy of operation.
