The question of clearance is often asked in the case of lead screw nuts made of polymer. This describes the lost motion, i.e. the “dead travel” on the lead screw, or in other words the gap between the thread flanks of the lead screw and the lead screw nut. The term clearance is often used […]
At first glance, many advantages of plain bearings sound attractive for use as roller. They use less space than roller bearings, require no additional lubrication (depending on their type) and do not suffer as much from dirt and cleaning agents. On top of that they weigh less and are cheaper. But as usual, devil is […]
If you are facing scoring mark issue in your existing stainless steel linear guide solution then you are reading a right article. People are using SS linear guide solution mostly in pharmaceutical, packaging & chemical industry where highly corrosive substances are coming in directly contact with system. Stainless steel corrosion resistance is a result of […]
In general, efficiency indicates how high the effectiveness of a device is when conversion losses are taken into account. The efficiency describes the relation between the delivered power (effective output) and the supplied power or loss and expenditure. In the calculation, the efficiency is abbreviated with a small eta (η). The result of the efficiency […]
What does “thread” actually mean in relation to a lead screw? And what is the difference between single and multi-start threads? Lead screws are machine elements that convert a rotary movement into a translatory one. Lead screws consist of a cylindrical round rod on which a simple transmission thread is attached. The transmission threads can […]
New, cost-effective drylin linear bearing ensures fast, lubrication-free movements igus, a motion plastics specialist, showcases what plastics can do with its first drylin W linear bearing made entirely of tribo-polymers. The linear bearing has been developed specifically for linear movements. At just ten grammes, it is quick to install, vibration-dampening, lubrication-free and ideal for transportable […]
Everyone has seen them at some point. Individual solar modules on a house roof or many of them arranged to create a solar power plant. These solar modules are generally fixed in place, oriented optimally to catch the sun. In large solar power plants, energy is generated more efficiently with special tracking systems, the “solar […]
Producing energy from renewable sources is always associated with high costs and investments. Various factors such as procurement, financing, and operating costs play a significant role. An important consideration is the system’s service life – a long one means that these costs can be recouped over a longer period. Photovoltaic systems, especially solar modules, nowadays […]
Lead screw drives are used in machines in a wide variety of industries. The demands on the lead screw drives therefore differ: high and low speeds and loads as well as wide temperature ranges or a continuous temperature of around 200°C. Even in these situations, lead screw nuts and lead screws have to work reliably. […]
Whether the snack dispenser in an office, the reverse vending machine in a shop or an ATM on the street, they all have to perform their service without interruption, if possible 24/7. This alone is a great challenge for a vending machine manufacturer, as customers do not wait and, at the latest when they spend […]
