The SL cross-type Oldham coupling is a type of metal slider coupling that is designed to provide a reliable connection between two shafts. This coupling is commonly used in various industrial applications, particularly in the automotive and air compressor industries. The coupling consists of two half couplings that are each supplied with tenons that are perpendicular to the middle slider. The tenons are inserted into the coupling groove, forming a moving pair. The slider moves in the groove of the slide when there is an axial misalignment or deflection, making it a suitable solution for low-speed and high-load transfer. It is important to add lubricating oil to the working face groove and the slider to ensure smooth operation and to prevent wear.
