Positive Control of Spring Pressure
Accurate spring alignment is maintained by using a stainless rivet with a long shank on larger sizes of our Ball Plungers. This precisely positions the spring for more accurate ball travel and provides positive control of spring pressure. Conventional floating discs are easily misaligned, while the rotation of the inner ball on dual-ball plungers results in less wearability on both the spring and the ball.

Longer Spring Life
By minimizing the lining pin head thickness, ouris able to use the longest possible springs. This, of course, means less fatigue and longer spring life.

Uniform Ball Projection
The distance by which the ball projects from the body of the plunger must be uniform from plunger to plunger. This uniformity is maintained by precisely controlling the crimping pressure applied to the neck of the plunger. Accurate machine controls plus rigid inspection procedures keep variances in ball projection to within ±.005".
