THK BNS1616AE448.5LC5 Ball Screw Spline Assembly

The THK BNS1616AE448.5LC5 is a compact, integrated ball screw and ball spline assembly that enables simultaneous linear motion and torque transmission on a single 16 mm shaft. It features a 16 mm screw diameter and a 16 mm lead, with an overall screw shaft length of 448.5 mm and a C5 accuracy grade for precise positioning. The assembly combines a precision ground ball screw and ball spline on one shaft, allowing high-speed travel without a separate guide mechanism. Key dimensions include a ball center diameter of 16.65 mm, ball screw nut outside diameter of 52 mm, flange diameter of 68 mm, and a ball screw nut length of 43.5 mm. Constructed from hardened alloy steel, it is lubricable with grease or oil and designed for long service life. Common applications include industrial robots, semiconductor equipment, automated assembly systems, machine tools, and other precision automation machinery; maintenance teams and system integrators use this unit for equipment repair, retrofit, expansion, and replacement. As part of the THK BNS series, it provides compact construction, low friction, and reliable simultaneous travel and torque transmission, eliminating the need for separate drive components while maintaining high accuracy. The AE suffix is a THK factory configuration code.
