Linear bearings are a type of bearing that "bear" or support the load of the carriage during its single-axis linear movement and provide a low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line, back and forth, along the length of the guide rail. The guide rail is fitted and inserted into the linear bearing.
A linear bearing is a critical component of the linear guide assembly. Its applications are in cutting machinery, X-Y positioning tables, machine slides, industrial robots, and instrumentation systems. Either a motor-driven ball screw, lead screw, or manual force can be used to drive the motion. The single-axis motion is limited in the X-Y plane.A rod end bearing is a common type of mechanical joint used on the ends of control rods. The steering columns in most cars, trucks and other vehicles, for example, feature tie rods with a rod end bearing. Of course, tie rods are designed to connect a vehicle’s steering rack to its steering knuckle. As a result, tie rods must be able to rotate according to the direction in which the wheel is turned. Rod end bearings allow tie rods to perform this rotation in a precise and controlled manner. To learn more about rod end bearings and how they work, keep reading.
A pulley is a mechanical device which contains a wheel and rope/belt/chain to lift the heavy objects. The wheel of the pulley is generally fixed to a hinge and rotates on an axle or shaft. In a simple arrangement of the pulley, chain/rope/belt/cable is the driving element that drives over the wheel. At the one end of the rope, the object is loaded, and from the end, when the rope is pulled down the object lifts. To lift large objects an assembly of pulleys are used. These are also used to transfer power from one rotating shaft to another. The advantage of the use of pulleys is that by applying a little force heavy objects can be lifted. In other words, the pulleys multiply the force to lift the heavyweights which cannot be lifted with bare hands.Covers and casings, small-sized spare parts for the automotive industry or radio-television or household equipment, non-standard tools and handles ,coupling and other 3D parts – all that may be created thanks to 3D printing technologies in a fast and economic manner.
Lead Screw | Applications, Advantages, Disadvantages, Types
What is a lead screw?
Lead screw is a type of screw which is used as linkage in machines. It converts rotary (or turning) motion into linear motion.Due to large contact area between male and female members of a lead screw, it has very high frictional losses.
