NOTES:Dimensions are expressed in mm, and subjected to manufacturing tolerances. Data can be altered without notice by our Design Department for the product benefit.* The stated movements are solely valid with the joint subject to a single movement direction. Values are proportionally reduced along with the movement combination.* Given tolerance installed and movements allowed are valid for rubber bellows. For bellows with PTFE sleeve, values must be reduced by 1/2.* Increasing temperatures reduce the permissible movements capacity and number of cycles. Dimensions are expressed in mm
