THK Co., Ltd. 2LT30UU595L Ball Spline Assembly

The THK 2LT30UU595L Ball Spline Assembly pairs a 30 mm shaft with a 595 mm shaft length to transmit simultaneous linear motion and rotary torque with high accuracy and low friction. It is part of THK's LT Medium Torque Ball Spline Series, featuring a precision-ground solid spline shaft and a cylindrical medium torque nut with UU double-end seals that protect against dust while retaining lubricant. The bearing type is a recirculating ball spline bearing, delivering high rigidity and smooth travel while enabling significant torque transfer. Key specifications include Brand: THK; Part Number: 2LT30UU595L; Model: LT30UU; Shaft Diameter: 30 mm; Shaft Length: 595 mm; Shaft Type: precision-ground solid spline shaft; Nut Type: cylindrical medium torque ball spline nut; Seal Type: UU (double end seals); Lubrication: grease or oil. Basic dynamic torque rating is approximately 273 N·m and basic static torque rating is approximately 538 N·m; basic dynamic radial load rating is approximately 19.3 kN and basic static radial load rating is approximately 33.8 kN. Common applications include industrial robots, automated assembly systems, semiconductor manufacturing equipment, CNC machinery, packaging machines, and material handling systems requiring synchronized linear and rotary motion. This assembly is well-suited for new equipment construction, precision retrofits, repairs, and replacement of worn torque-transmitting linear motion components where compact form, high rigidity, and accurate positioning are essential.
