Ball-Nose Spring Plungers
 |
 |
Align, position, and lock moving parts for most machining and assembly tasks. These spring plungers have a spring-loaded ball that compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place. Unlike long-nose spring plungers, the ball rolls easily in and out of position, so they're a great fit for applications that require consistent, smooth movement, such as positioning parts in an assembly line and aligning fixtures and jigs when cutting or drilling.
Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.
440C Stainless Steel Nose—The strongest, most wear-resistant stainless steel noses, these grind against hard metal surfaces without denting or scratching. However, they are not as corrosion resistant as 316 stainless steel.
Nylon Nose—Extra soft to avoid scratching delicate surfaces. Nylon is best for use on soft materials, such as aluminum. It will swell and weaken when exposed to moisture, however, so it should only be used in dry environments.

Knob-Grip Retractable Spring Plungers
 |
With the most versatile handle we offer, these fit in tight spaces while still giving you something to grab. A tug retracts the nose so you can make controlled adjustments. Use these spring plungers for everything from positioning workpieces to changing the height of tables and platforms.
Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.
Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. Steel is best for dry environments, however, since moisture will cause it to rust.
18-8 Stainless Steel Nose—The choice for wet and outdoor environments, 18-8 stainless steel resists rusting. It's strong enough for most jobs, but won't withstand stress and vibration as well as steel.
Twist-to-Lock—Free up both hands to adjust your workpiece or switch out parts without the plunger springing back and getting in the way. Pull back the handle and twist to lock the nose in its retracted position.

Long-Nose Spring Plungers
 |  |
 |
Lock heavy moving parts securely in place. Often used in indexing applications, these have a longer nose than ball-nose spring plungers to withstand greater side forces without disengaging. The nose compresses when a part presses against it, and then pops out into deep notches or grooves for a strong hold.
Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.
Acetal Nose—The best plastic for damp and wet environments, acetal won't swell or lose strength if exposed to moisture. These noses are extra soft to avoid scratching delicate surfaces. They are best for use on soft materials, such as aluminum.

Vacuum Cup Levelers
 |
 |  |
Female Connections | Male and Female Connections |
Save time aligning your vacuum cups manually between pick-and-place tasks. Also known as spring plungers, these levelers use a spring to automatically adjust for height and alignment differences with each stroke. Because the spring also creates a gentle point of contact with your object, these levelers help your vacuum cups last longer. They don’t rotate, so your object will stay in the same position—use them in repetitive vacuum lifting applications where precision is required.
Choose levelers based on the required stroke length and thread compatibility with your cup and system. Tighten the mounting nuts on the body to secure them in a panel or to a mounting bracket.
Anodized Aluminum—Aluminum levers are a good choice for end-of-arm tooling. Thanks to their light weight, they allow for faster cycle times than brass and stainless steel levelers.

Food and Beverage Vacuum Cups for Curved and Irregular Objects
 |
Thread these cups onto your vacuum system to lift and move sanitary items with curves, corners, and uneven surfaces. They have bellows that compress as they contact an object for a better hold than flat cups. The more bellows a cup has, the tighter the hold on a variety of shapes. Made of silicone rubber, these cups withstand the extreme temperatures in food processing applications. They're also FDA compliant for direct contact with food.
Warning: Never use to lift people or items over people.
Metal-Detectable Vacuum Cups
 |  |
Multiple Bellows, Male | Male |
Metal-detectable cups have a metal additive that sets off metal detectors if they fall into your line. They're bright blue, so they're easy to find and remove. They help you comply with Hazard Analysis and Critical Control Point (HACCP) programs to keep contaminated food from leaving your facility. Designed for thorough cleaning, these cups don't have pits, crevices, or tight angles where bacteria can hide.
Plastic Fitting—Cups with a plastic fitting are much lighter than stainless steel fittings, so they won't weigh down your robot arm. However, they are not as strong or corrosion resistant as stainless steel.
Stainless Steel Fitting—For applications with frequent washdowns, use cups with a stainless steel fitting. They won't corrode from water and harsh cleaning agents. They're stronger than plastic fittings, but they're also heavier.
