Cushioning Pins & Steel Bushings

Hydraulic & pneumatic cylinders including shocks have a term called cushioning. Cushioning is required to decelerate a cylinder’s piston stroke before it hits its lowest point and strikes the end cap. Excess cushioning increases the time it takes for the piston to reach the end of its stroke, and not enough cushioning increases the impact shock at the end of stroke.

The Power of a Square Ball U-Joint

The universal joint has remained fundamentally the same for more than a century. One of CCTY’s design teams, John Sweetwood and Rich Perlberg, found a way to simplify the design making the movement smoother and stronger. The conception of a square ball made it possible. A universal joint can contain more than 100 individual components. …

The Case for Matching Shaft with Self-Lubricating Bushings

A bushing design that experiences frequent start-ups and shut-downs can lead to premature wearing – or even failure. This also happens when a bushing runs too dry, for example when there is a sudden loss of contact lubrication, an aggressive contamination influence or simply an under-designed mating shaft.

Metal-Polymer Bushings and High Load Applications

One of the chief difficulties in traditional bushing design is lowing friction and preventing premature wear, despite lubrication. This lifecycle concern comes as no surprise given that efficient machines run around the clock and typically produce varying degrees of heat profiles within the operating systems. A secondary lubrication source, such as a costly grease or oil, should be avoided but may need to be considered to help manage the destructive heat influences.
