THK BNT Since the mounting screw holes are machined on the square ball screw nut, this model can compactly be mounted on the machine without a housing.
A threaded hole for installation is machined on the square nut, which can be assembled directly with the mechanical body without a support seat.
Structure and specialty of type BNT:
1. THK rolling ball screw is an inexpensive feed screw. It replaces the expensive grinding screw shaft used in precision ball screw by precise rolling forming and special surface grinding.
2. The rolling surface of the steel ball of the combined nut is all grinded and polished. Compared with the traditional rolling ball screw, the axial clearance is smaller and the motion performance is smoother.
3. all types have been standardized, and the best choice can be made according to their usage.
