Linear Actuator Offers High Positional Accuracy

Linear Actuator Offers High Positional Accuracy Schaeffler UK has extended its linear actuator range to include a unit with a linear ball bearing guideway and ballscrew drive, offering high positional accuracy and speeds of up to 2.5m/s, ideal for automation, handling, assembly and sheet metal forming applications. Schaeffler UK has extended its MKUVE series of linear actuator modules with a unit that comprises a linear ball bearing guideway assembly and ballscrew drive. The units are also easily interchangeable with other linear components in Schaeffler's range.The MKUVE20-KGT module is ideal for moving moderate loads with high positional accuracy (up to a maximum speed of 2.5m/s), while supporting high-moment loads about all three axes.The module incorporates Schaeffler's recirculating ball guidance system with two carriages, the KUVE20-S. This enables the movement of moderate loads with high rigidity.The actuator unit is protected using bellows.The module is driven by a ballscrew drive, which has a nominal spindle diameter of 20mm and a pitch of 5, 10, 20 or 50mm.For 5 and 10mm pitch sizes, a pre-loaded double nut is available.The spindle is supported by an axial, angular contact ball bearing from Schaeffler's ZKLF series. The guidance system and drive are integrated in an extremely rigid support rail that can be easily matched to the customer's machine or production equipment using simple T-slots, making life easier for machine builders and systems integrators.
