The Machinery Mounting Solutions Spherical Spacer accomplishes two functions: 1) it creates fastener planes and 2) bolt elongation. The RotaChock® by design is capable of taking the clamping force created by the hardware at any length. We offer the spacer to suit your application while creating a fastener that is in pure tension and no longer a maintenance problem for the life cycle of the machine. The illustration below and the table depicts our part number and diameters offered Off-The-Shelf. The angular offset maximum angle is 4 degrees.
The whole mounting system includes the machine's foot, foundation, chocks and the fasteners. Wherein fasteners that are not in pure tension will be a loose fastener. If you have fasteners that loosen, epoxy resins that crack, shims that walk-out or a MAC that loosens contact us, we may have your solution. It's not the chock.
Warning; All spherical washers (spacers) are not the same contact us!!
