By using the LIFTKIT / SLIDEKIT series, which are official UR+ accessories from Evarix, you can expand the vertical range of motion of UR robots with LIFTKIT, and the horizontal range of motion with SLIDEKIT, significantly improving the work efficiency when using UR robots. (UR+ certified) It is possible to use either LIFTKIT or SLIDEKIT according to your needs, but using them in combination will further increase the degrees of freedom in the motion range of the UR robot. Evarix's LIFTKIT and SLIDEKIT come with dedicated plugin software (UR Caps) in addition to the linear motion mechanism itself, making setup easy. (*Please contact your local UR distributor when considering implementation.) In addition to UR robots, we have also started offering LIFTKIT / SLIDEKIT series specifically for Omron and ABB collaborative robots. Furthermore, we have a series available for use with collaborative robots from other manufacturers, so please consider this as well.

Kingsbury's "LEG Direct Lubrication" oil film bearings are a high-efficiency type that directly supplies lubricating oil to the pad surface. Not only does it achieve significant reductions in oil supply volume and loss horsepower (mechanical loss) compared to conventional oil sump types, but it also realizes lower pad surface temperatures and increased load capacity compared to other direct lubrication methods. The LEG type oil film bearings include thrust bearings and journal bearings in their lineup. 【Features】 (*For LEG thrust bearings) ■ Pad surface temperature decreases by 8 to 28°C compared to conventional types ■ Load capacity increases by 15 to 35% ■ Lubricating oil volume decreases by up to 60% ■ Loss horsepower (mechanical loss) is also reduced by 45% It is possible to upgrade not only new rotating machinery but also the efficiency and load capacity of currently operating rotating machinery by replacing existing bearings with LEG type oil film bearings while maintaining the same bearing size.
