Hardened Bearing-Quality 440C Stainless Steel

These balls are hardened for increased wear and abrasion resistance.

Tight-Tolerance Hardened 440C Stainless Steel

With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.

Impact-Resistant 440A Stainless Steel

440A stainless steel resists damage from impact and abrasion. It's often used for cutlery and valve components.

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Tight-Tolerance Multipurpose 304 Stainless Steel

This material has tighter tolerances than standard 304 stainless steel.

Hard Wear-Resistant 52100 Alloy Steel Balls

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. These balls are often used in bearings.

Tight-Tolerance Hard Wear-Resistant
52100 Alloy Steel Balls

The diameter on these balls is held to a precise tolerance.

Low-Carbon Steel Balls

Also known as mild steel, use these low-carbon steel balls in parts that don't require high strength.

Ultra-Hard C2 Tungsten Carbide Balls

260 Brass Balls

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

Super-Conductive 102 Copper Balls

With 99.99% copper content, 102 copper has higher purity than 110 copper, resulting in superior electrical conductivity. It's commonly called OFE and OFHC copper. Use it in electrical applications, such as for coaxial cables and terminal lug.

2017 Aluminum

Widely used as bearings and in valves, 2017 aluminum is a durable, lightweight material.

Hollow Corrosion-Resistant 3003 Aluminum Balls

Hollow construction reduces weight and allows these balls to float.

Hardened Shock-Resistant S2 Tool Steel

This S2 tool steel has been hardened for excellent strength and impact resistance. It has a tough core that resists breaking under shock loads.

High-Strength Grade 5 Titanium Balls

Grade 5 is the strongest of all the titanium alloys thanks to its higher aluminum and vanadium content. It offers a versatile mix of good corrosion resistance, weldability, and formability.

Lead Balls

Fill forming bags for shaping metal or use as a counterweight.

Threaded-Hole Ball Knobs

Install these traditional, easy-to-grip ball knobs on a threaded stud. They're good for control levers and push-pull rods.

Clamping and Workholding

Tooling Balls

The shoulder on these tooling balls provides a consistent height reference point.

Adjustable-Height Tooling Balls

Install tooling balls in a workpiece or fixture to create a precise measurement reference point. Push the shank further into the hole to adjust the height of the ball.

Tooling Ball Covers

Protect tooling balls when not in use.

Tooling Ball Mounting Pads

Use a mounting pad when your tooling ball needs a raised mounting point.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005".

Ball Transfers

Stud-Mount Ball Transfers

Install in a threaded hole or use a nut to secure.

Heavy Duty Stud-Mount Ball Transfers

These ball transfers have capacities up to 2,200 lbs.

Washdown Stud-Mount Ball Transfers

Ball transfers have a double-sealed ball to keep out dirt and debris. Side vents expel contaminants.

Heavy Duty Press-Fit Ball Transfers

These ball transfers have capacities up to 2,200 lbs.

Shock-Absorbing Press-Fit Ball Transfers

The ball in these transfers is spring-loaded to absorb impact.

Flange-Mount Ball Transfers

The flange has mounting holes for fastening.

Heavy Duty Flange-Mount Ball Transfers

These ball transfers have capacities up to 2,400 lbs.

Shock-Absorbing Flange-Mount Ball Transfers

A thick rubber cushion underneath these ball transfers absorbs impact and reduces vibration.

Washdown Flange-Mount Ball Transfers

Ball transfers have a double-sealed ball to keep out dirt and debris. Side vents expel contaminants.

Recessed Flange-Mount Ball Transfers

Transfers recess into the mounting surface for a low profile.

Heavy Duty Recessed Flange-Mount Ball Transfers

These heavy duty ball transfers recess into the mounting surface for a low profile.

Washdown Recessed Flange-Mount Ball Transfers

Ball transfers have a double-sealed ball to keep out dirt and debris. Side vents expel contaminants.

Shock-Absorbing Recessed
Flange-Mount Ball Transfers

The ball in these transfers is spring-loaded to absorb impact.

Pop-Up Ball Transfers and Stops

These ball transfers and stops rise when you supply air and retract into the housing when air supply ceases.

Create-Your-Own Ball Transfer Plates

Snap these ball transfers together like jigsaw pieces to create a custom ball transfer plate, or use them unconnected to create your own pattern for rotating and positioning material. They have magnets embedded in the frame, so you can mount them on any flat magnetic metal surface and rearrange them as your operations change.

Material Support Stands

Ball-Transfer-Top Support Stands

Ball transfers allow movement in any direction so you can turn material without lifting it.

Build-Your-Own Support Stands

Flagpole Ball Ornaments

Floats for Water and Oil

Floats for Threaded Rods

Connect these floats to threaded float rods.

Floats without Connections

These floats are untethered by a float rod so they can float freely in your tank.

Through-Hole Floats

The through-hole connection allows these floats to slide up and down a vertical float rod.

Hitches

Tow Hooks

For an easy towing connection, mount these hooks to a bumper or trailer.

Hitch Inserts

Use these inserts in hitch-ball connections.

Mounting Plate Inserts for Drawbar Couplers

These inserts allow you to connect drawbar couplers to a receiver.

Drawbar Rings

These rings mount to a trailer and connect to the drawbar coupler or tow hook on a vehicle.

Drawbar Couplers

Also known as pintle hitches, drawbar couplers are used with drawbar rings to connect a trailer to your vehicle for towing.

Hitch Receivers

Mount these receivers to your vehicle. Use them with an insert and pin for a complete hitch.

Neodymium Magnets

Nickel plating gives these magnets good corrosion resistance.
