About Gas Springs
Gas springs are typically used to assist in opening lids, covers, windows, conveyors, and seats—similar to a hatchback opening on a car.

Tooling Balls
The shoulder on these tooling balls provides a consistent height reference point. Use the ball as a point from which any other point can be precisely measured, such as when determining hole centerlines and distances between hole centerlines.
Slip-fit tooling balls have a slightly undersized shank for temporary mounting. Secure from the side with a set screw (not included).
Tooling balls with a threaded hole secure from the bottom by threading a cap screw (not included) into the shank.
Two-piece tooling balls are welded to the shank. If excessive horizontal pressure is applied to the ball it will break off to prevent bending the shank or distorting the tight tolerances of the ball.

Stud-Mount Ball Transfers
Install these ball transfers in a threaded hole or use a nut to secure.
Steel balls are durable. Stainless steel balls offer the most corrosion resistance. Nylon and polypropylene balls are nonmarking. Nylon is stronger than polypropylene. However, polypropylene resists chemicals better than nylon.
Ball transfers with an angled working orientation can be used to form support stands.
Capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the capacity stated.
