Spring Plungers Spring Plunger tips made by most manufacturers,are case hardened. This means they have a protective shell, about .10" deep.Beneath this shallow veneer is mild, untreated steel. The our plungers are fabricated from hardened steel.our Spring and Ball Plungers have accurate end forces, are easy to install, and are competitively priced. They are manufactured in the U.S.A. in a ISO 9001 certified quality system.And if these aren’t enough reasons to specify our Spring and Ball Plungers, here are a few more: Better Point of Contact The our plungers are turned and the tips generated in one smooth continuing process. This results in a constant radius tip, perfectly tangent to the point where the tip joins the shaft. Conventional two step, turn and grind operations,can leave ridges on the shaft at the tip junction and can also produce out-of-round tips.These,in turn, can gouge or score finely finished parts or can cause detent cams to hang up or stick. Extra Length Springs for Longer Life The longer the spring, the longer its life.our goes to extra lengths to minimize the thickness of the base flanges on all of its plungers. That allows us to use longer springs with less chance for fatigue and breakage. Improved Plunger to Body Alignment The long base flange allows for a larger bearing surface. This means improved plunger-to-body alignment, truer travel, and much improved side load characteristics. Tighter Fit Resists Contamination Closer machining tolerances, minimum plunger-to-body clearance, and smoother plunger finish make our plungers fit more snugly in the plunger bore. This improves plunger alignment and provides extra resistance to contaminant entry. The results: dirt and grit cannot get to the bearing surfaces to shorten the life of the plunger. Better Plunger Adjustment The Solid Drive?design assures that during removal or adjustment of the plunger,the whole plunger is moving, not just the set screw. This means no lost parts or springs falling out of the plunger. Product specifications: The first type specification: long, short. Stretch levels: light and heavy. point material: SCM435, SUS304, Nylon 66. Plunger head material: S45C, SUS440, SUJ2, ceramics, resin, polyacetal, fast cutting of copper. Thread Specifications: Metric: M4 * 0.4, M5 * 0.8, M6 * 1.0, M8 * 1.25, M10 * 1.5, M12 * 1.75, M16 * 2.0, M20 * 2.5 Inch :6-32, 6-40, 8-32, 8-36, 10-32,1 / 4-20, 5/16-18, 3/8-16, 1/2-13, 5/8- 11, 3/4-10, 1-8 Our Spring & Ball Plungers Last Longer 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". Product specifications: The first type specification: long, short.

As a result of the traditional set screws is all-in-one, and the head high hardness, long lead shaft, gear wear, etc., in view of the situation of foreign equipment vendors usually dog point, soft point set screws to obtain a relatively good results, the liner companies stop Hexagon head screws with a precise end-pressure, easy to install, and at competitive prices. Products in accordance with the ISO 9001 quality certification system. Because of its relatively low hardness of the head material, to products used to connect only when the moving block has a stop block on the protection components are widely used in foreign assembly closely. For example, copper stop block, aluminum blocks, plastic blocks, such as low hardness, the working frequency components. Product specifications: Body material: SCM435, SUS304, Nylon 66.
