A Single Cross Roller Bearing That Can Handle High Axial, Radial, and Moment Loads! Are you tired of struggling with heavy loads in your machinery? Well, we've got the solution for you! A single cross roller bearing is designed to handle high axial, radial, and moment loads, making it perfect for demanding applications. However, if you're planning to print one out of PLA instead of using steel, be aware that its performance may be compromised. But don't worry, with a little creativity, we can still create an effective solution! Using Pennies as Rollers Why not repurpose some pennies to serve as rollers in our single cross roller bearing? Not only will this provide an entertaining project for kids, but it's also a great way to declutter your change jar! To begin, follow the steps outlined below. Assembly Instructions Please refer to the accompanying photos for detailed instructions. Firstly, print the lower and upper races using a layer thickness of 0.2 mm and three perimeters each. The inner and outer races are split in two parts, connected with tabs to facilitate assembly. Make sure to remove any excess material left behind from printing. Now it's time to assemble the 10 pennies into alternate angles within the lower races. Use a pointy object like a pin or an awl to gently push them into place. Once you have your pennies arranged, tilt the upper races and carefully slide the outer race halves together, applying superglue as needed. If you encounter any small gaps between the two halves, consider using a gel-type superglue to fill in the space. Lastly, glue the inner race halves together using the same technique as above, then trim away the connecting tabs so that the bearing can spin smoothly.
