150 mm ID Bearings | McMaster-Carr

For a more compact machine, these bearings have thinner inner and outer rings than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.

Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

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.

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.

Static-Control Maintenance-Free Turntable Bearings

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.

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.

Needle-Roller Thrust Bearings


Bearings	Washers

Small but mighty, our thinnest rolling thrust bearings slot into tight spaces and spin at whirring speeds. Their long, slender rollers support thrust loads and reduce friction in everything from machine tool spindles to gearboxes.

A cage holds the rollers in place. You can install these bearings without washers between hardened, ground surfaces for the thinnest profile. If you’re working with unhardened, unground surfaces, you’ll need two washers for the rollers to run on. This three-piece design is easy to lubricate, but the oil will attract dust and grime since it’s exposed.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
