Linear bearings

Part: Linear bearings

Tools:	3D printers

Challenges

Static structures are not sufficient for reproducing most useful objects.

Approaches

Bearings allow frames a variety of motion in relation to each other and other components.

Linear Bearings

To use the captive hex holes, insert bolts from the inside of the linear bearing, pointing out toward the frame.

  Linear bearing rail mount

To do

• extend bearing block to encompass an additional frame in one dimension, bevel corner of that frame to avoid contact with the linear rail
• modify corner reinforcement to allow for through-bolting with a double-length bolt instead of a triple.
• hollow out bearing race portion of part, to allow for easier attachment of internal nuts and bolts.
• design a version which bolts to standardized steel linear rail and linear recirculating ball bearing carriages

Parts
