The bearing consists of smooth rollers or metal balls and smooth inner and outer surfaces (called raceways) on which the rollers or balls roll. These rollers or balls act as a load carrier for the device, allowing it to rotate freely. Bearings usually encounter two kinds of loads: radial load and axial load. Radial loads occur perpendicular to

How to Convert from Rotational to Linear Motion [GUIDE]

The rod travels in a straight line (linear motion), returning to the tube after completing a 360-degree rotation. But this linkage is unique in that both the rotational and reciproing motions can initiate the conversion. In other words, the rod can tug the wheel to roll first.
