THK Co., Ltd. 2LT30UU595L Ball Spline Assembly

Description:

The THK 2LT30UU595L Ball Spline is a precision ball spline assembly featuring a 30 mm spline shaft with a 595 mm shaft length, designed to simultaneously transmit linear motion and rotational torque with high accuracy and low friction. Commonly installed in industrial robots, automated assembly systems, semiconductor manufacturing equipment, CNC machinery, packaging machines, and material handling systems requiring synchronized linear and rotary motion. Machine builders, maintenance technicians, and automation integrators use this ball spline assembly for new equipment construction, precision retrofits, repairs, and replacement of worn torque-transmitting linear motion components.

Applications:

The THK 2LT30UU595L belongs to THK's LT Medium Torque Ball Spline Series, which combines a precision-ground spline shaft with a recirculating ball spline nut to provide smooth linear travel while transmitting rotational torque. The UU designation indicates double end seals that protect against dust and contaminants while retaining lubricant for extended service life. With its 30 mm shaft diameter and 595 mm shaft length, this assembly is ideal for high-speed positioning systems, robotic actuators, pick-and-place equipment, indexing mechanisms, and factory automation applications where compact construction, high rigidity, and accurate linear guidance are essential.
