12.2 mm ID Bearings | McMaster-Carr

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Ultra-Low-Friction Dry-Running Thrust Bearings

Use these bearings in applications with frequent starts and stops because they operate with very little friction.

PTFE bearings have good chemical resistance.

Rulon J bearings create the least amount of friction of any bearing that we offer. They handle heavier loads than PTFE bearings.

Water-Resistant Dry-Running Thrust Bearings

Good for underwater applications, these bearings won’t swell or warp when wet.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Food Industry Dry-Running Thrust Bearings

Made of FDA listed materials for use in food applications, these bearings also withstand caustic and washdown environments.

Rulon 641 bearings are stronger than UHMW bearings and withstand a wider range of temperatures.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Metric Press-Fit Drill Bushings with Head

Shown in Countersunk Hole

Shown in Standard Hole

Even under extreme drilling pressure, these metric bushings won't press through your jig plate. A flanged head on the top of the bushing acts as a stop, preventing it from moving as you push down your drill bit, reamer, or other cutting bit. Drill bushings ensure accurate, consistent cuts and drilled holes from one part to the next. They sometimes also work as spacers, shims, and machinery bushings. Made of hardened, ground steel, these bushings hold their shape and resist wear over time. The flanged head protects your jig plate from damage caused by heavy use.

Although it's no longer an active standard, DIN 172 is still a common reference point for making sure parts are compatible with other parts and tools.

These bushings work in both countersunk and standard drill holes. To install, place the bushing inside the hole in your jig. A chamfered edge on the bottom of the bushing helps center the bushing in the hole. Once centered, press the bushing into the hole with a hydraulic or lever press.
