450 mm OD Bearings | McMaster-Carr

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.

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.
