6.2 mm ID Bearings | McMaster-Carr

Made of naturally slippery plastic so there's no lubricant to maintain or make a mess. These bearings are ideal for spic-and-span spaces since oil won't drip off, wash out, or collect dust over time. They'll also never rust.

Ultra-Chemical-Resistant PTFE—The most chemical-resistant bearings we offer. PTFE is immune to harsh chemicals, including all strong acids and bases. It's also one of the slipperiest types of plastic, but it's not very strong.

High-Load Moisture-Resistant Rulon LR—Similar to acetal, these bearings won’t swell from water or humidity, plus they support higher loads.

Ultra-Low-Friction Rulon J—These bearings glide effortlessly on machines with frequent starts and stops, such as conveyors. They're also stronger than PTFE bearings.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings. These bushings are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

All bushings have a chamfer on the outside that centers the bushing as you place it into the hole. Press into place with a manual or hydraulic press. Since the bushing is sized slightly larger than the hole for an extremely tight fit, it’ll stay put permanently. These are ANSI Type PM bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.

They also have an internal chamfer that makes it easy to insert bits, pins, and punches without damaging the bushing or misaligning tools.

Both Ends—Bushings with an internal chamfer on both ends allow you to insert tools no matter which end of the bushing is inserted into the jig. However, having an internal chamfer on the bottom of your bushing may cause shavings to get caught and bind as you remove the bit.

DIN 179—DIN 179 bushings meet dimensional and material standards that make sure they're compatible with other parts and tools. Although DIN 179 is no longer an active standard, it's still a common reference point for designers.

Dry-Running Thrust Bearings for Food and Beverage

Made of slippery, FDA-compliant plastic, these bearings are safe to directly touch food. Install them right inside food-processing equipment, such as mixers and fillers. They won’t impart odors, tastes, or harmful impurities, plus there’s no lubricant that could drip off or wash out. With no lubricant to replenish, these bearings also reduce maintenance and downtime.

Ultra-Low-Friction Rulon 641—Get effortless motion with strength surpassing UHMW polyethylene. Rulon 641 bearings can also operate from cryogenic to oven-like temperatures.

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. They’re ANSI Type H bushings, also known as headed bushings. A flanged head acts as a stop, so these bushings won’t move as you push down your drill bit, reamer, or other cutting bit. Use them even in jigs made of thin or soft materials—the head adds support to protect your jig from damage caused by heavy use. Drill bushings ensure accurate, consistent cuts and drilled holes from one part to the next. They’re also used as spacers, shims, and machinery bushings. Made of hardened, ground steel, these bushings hold their shape and resist wear, so they last for many cycles without needing to be replaced.

These bushings meet DIN 172 dimensional standards. This standard is no longer active, but it’s often used as a reference point for making sure parts are compatible with other parts and tools.

To install, fit the bushing into a hole in your jig. In a standard hole, the head will sit above the jig plate; to mount flush, install in a countersunk hole. A chamfered edge on the bottom of the bushing helps center the bushing in the hole. Once it’s centered, press the bushing into the hole with a hydraulic or lever press.
