THK BTK2005-2.6882LTK BALL SCREW ASSEMBLY

Description:

The THK BTK2005-2.6882LTK Ball Screw Assembly is a precision Ball Screw/Spline assembly featuring a 20 mm screw shaft diameter, 5 mm lead, and an overall screw shaft length of 882 mm. Designed to provide simultaneous precision linear motion and torque transmission, it combines a ball screw and ball spline into a compact assembly for high-rigidity, high-accuracy motion control. Commonly installed in industrial robots, semiconductor equipment, automated assembly machines, medical devices, and precision automation systems. Maintenance teams and system integrators use this assembly for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK BTK2005-2.6882LTK belongs to the THK BTK Series Ball Screw/Spline assemblies. The base model BTK2005 features a 20 mm screw shaft diameter and a 5 mm lead, integrating a precision ball screw with a ball spline on a single shaft. This design enables simultaneous linear motion and torque transmission while eliminating the need for a separate linear guide in many applications. The "882L" designation identifies an overall screw shaft length of 882 mm. The suffix "2.6" is part of the standard BTK model designation, while the suffix "TK" represents a THK manufacturing or end-machining configuration that is not publicly decoded by THK and therefore should not be interpreted without the original engineering drawing.
