0.128" ID Bearings | McMaster-Carr

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components. With an open design, they dissipate heat more efficiently than one-piece thrust ball bearings.

Secure-Hold Drill Bushings for Plastic

Designed to grip slippery plastic, the knurls on these bushings keep them from spinning while you drill. Their hold is stronger than serrated bushings, so they can withstand more force. Press or mold into plastic tooling to guide your drill bit and create accurate, consistent holes.

Drill Bushings for Plastic

Serrations line the sides of these bushings to keep them from spinning while you drill. Also known as jig bushings, they’re pressed or molded into plastic tooling to guide drill bits, counterbores, and reamers. They help you create consistent, accurate holes from part to part.

Drill Bushings for Soft Metal and Wood

Serrations on these bushings dig into wood, aluminum, and other soft metals to keep them from spinning while you drill. Also known as jig bushings, they fit inside fixture plates to guide drill bits, counterbores, and reamers. They improve accuracy so that your drilled holes and cuts are consistent from part to part.
