Convex Linear Motion Spline
The GJH convex linear motion spline is characterized by convenient assembly and compact structure. Since it operates with zero clearance or interference fit in the rotational direction, the convex linear motion spline can maintain high speed motion and rotation. Held by the retainer, the balls will not run out even if the spline shaft is pulled out of the nut. In addition, the linear motion spline has a long working life and high rigidity, for the spline bearing is made of HRC58 quenched alloy steel, and its spline nut is made of HRC58 quenched alloy steel or alloy structural steel that is carburized and quenched.
The convex linear motion spline comes with square spline nut. The outside surface of the spline shaft is designed with three equidistantly spaced crests, and on both sides of each crest, two rows of balls are arranged. Altogether there are six rolls of balls.
The GJH convex linear motion spline is suitable for use in spindle of spot welding machine, tool post, indexing shaft, arms of industrial robot, automatic loader, measuring instrument, wire winder, main shaft of automatic plotting machine, and main shaft of packaging machine, etc.
