Low-Profile Maintenance-Free Turntable Bearings

At 16 mm tall, these bearings are about the height of your typical plastic water bottle cap, so they won’t bulk up your builds. They handle radial, thrust, and moment loads. Often used to oscillate heavy equipment, find them rotating hoists or spinning components on robotic arms. The internal sleeve moves smoothly and will never require lubrication. For easy alignment and mounting, these bearings have holes on both the inner and outer ring. They’re also known as slewing-ring bearings.

Note: Listed capacities only apply when bearings are mounted parallel to the ground. Otherwise, they reduce when bearings are tilted.

Maintenance-Free Turntable Bearings


	Turntable Bearings with Gear Teeth

With low-friction internal sleeves made of PTFE, these bearings never need lubrication. Also known as slewing-ring bearings, they’re used for slow, controlled rotation. You’ll often see them rotating hoists, robotic arms, and other heavy machinery. They have holes on both the inner and outer ring, so they’re easy to align and mount.

Note: Listed capacities only apply when bearings are mounted parallel to the ground. These bearings can be mounted in other orientations, but their capacities will be reduced.

Turntable Bearings with Gear Teeth—Bearings with gear teeth can be driven by a spur gear. For components to mesh correctly, they must have the same pressure angle and module.

Easy-Adjust Clevis Rod Ends


Clevis Rod End

Make quick adjustments to these rod ends by inserting and releasing the clevis pins without the need to bend them into place. Also called yoke-end linkages, they support pivoting movement along one axis when threaded onto shafts, rods, valve pistons, and other assemblies. All are zinc-plated steel for moderate corrosion resistance.

Food and Beverage Maintenance-Free Turntable Bearings

Made of stainless steel and plastic, these bearings are FDA compliant for direct contact with food. Their low-friction internal sleeves never need to be lubricated. Often used to turn conveyors or spin mixers, these bearings are designed for slow, controlled rotation. They have holes on both the inner and outer ring, so they’re easy to align and mount. They’re also known as slewing-ring bearings.

Note: Listed capacities only apply when bearings are mounted parallel to the ground. These bearings can be mounted in other orientations, but their capacities will be reduced.

Precision Single U-Joints

Pin-and-Block

Joint

Pin-and-Block Joint

A good choice when you need accurate and repeatable motion, these U-joints have zero backlash (no play), so there’s no motion lost when your shafts change direction. This keeps machines running smoothly. They’re single U-joints, so they connect and transfer torque between shafts that are misaligned at an angle.

Your shafts’ misalignment will affect the speed and torque the U-joint will be able to transmit. The more the shafts are misaligned, the less speed and torque the U-joint will be able to transmit.

Pin-and-Block Joint—Pin-and-block U-joints work well in most applications since they handle higher torque at lower speeds than joints with ball bearings.

Acetal—Acetal U-joints weigh less than metal U-joints. They protect components in your system from stray electrical currents by blocking the flow of electricity between your shafts.

Set-Screw Shaft Mount—U-joints that connect with set screws don’t require you to drill any holes.

Lubrication Not Required—U-joints that don’t require lubrication are often used with optical devices and other sensitive equipment because they're less likely to attract dust and debris compared to lubricated U-joints. They’re also easier to maintain.

Static-Control Maintenance-Free Turntable Bearings

Image of Product. Front orientation. Turntable Bearings. Maintenance-Free, Static Control.

Safe enough to rotate equipment in microchip and semiconductor manufacturing, these bearings prevent harmful static buildup. They’re made from stainless steel and have specially formulated PTFE sleeves that work together to drain static. Make sure your set up provides a path to the ground.

Also known as slewing-ring bearings, these bearings are great for turning heavy equipment in a slow and controlled way. Their sleeves are also slippery, so they move smoothly and don't require lubrication. For alignment and mounting, they have holes on both the inner and outer ring.

Note: Listed capacities only apply when bearings are mounted parallel to the ground. These bearings can be mounted in other orientations, but their capacities will be reduced.

Extension Spring Stud Anchors

Black-oxide steel anchors create a rigid, adjustable mounting point for extension springs that won't shift under load. Thread them into your part for a secure connection that outperforms hooks and loops. Steel construction handles repeated spring tension without deforming, and the black-oxide finish provides mild corrosion resistance.
