Spherical Spacer

Where the RotaChock adjusts itself to an angle up to 4 degrees between the machine foot and the foundation, the foundation bolt is rigid and will tend to bend when it’s torqued down.

To ensure an optimum bolted connection, Chock Design offers spherical washers to compensate for the angle between the bolt head/nut and the foundation.

Our spacers are manufactured of 42CrMo4 alloy steel. Unlike the forged washers that are prone to breaking or even shattering under the load of high tensile bolts, our washers will keep up the tension and pre-stretch in the bolt even over long periods of time.
