Kate Precision Machinery Features of HTPM Ball Screw

High Reliability

From material and heat treatment to design, production, quality control, and delivery, HTPM follows established procedures. Our systematic management ensures high reliability for our ball screws.

High Efficiency

HTPM ball screws operate through the rolling motion of steel balls within the ball nut. The transmission efficiency of a ball screw is 2 to 4 times that of a sliding screw. Compared to sliding screw transmission, ball screw transmission can drive larger loads with less power, consuming only 1/4 to 1/2 the power of a sliding screw.

High Precision

HTPM ball screws and ball nuts are precisely machined, ground, assembled, and quality-controlled in a constant temperature room, ensuring high-precision quality.

High Rigidity

HTPM ball screws adopt a Gothic arch groove shape, allowing for optimal contact between the steel balls and the thread raceway for smooth movement. Adding appropriate preload to eliminate axial clearance can further enhance rigidity, reducing elastic deformation between the steel balls, ball nut, and ball screw and achieving even higher precision.

Excellent Durability

HTPM uses high-quality steel and our proprietary processing and grinding techniques to provide ball screws with excellent durability.

External Circulation Ball Screw

a. Structure

An end-cap type external circulation ball screw consists of a screw, nut, balls, and a return mechanism. The end-cap type external circulation structure features a ball return mechanism at the nut end and through-holes in the nut. Axial through-holes are drilled in the nut wall to serve as return channels for the balls. Return mechanisms are fitted to both ends of the nut. The return mechanism interfaces are tangential to the screw thread raceway and guide the balls into the return holes to form a closed loop.

b. Features

1) Suitable for a wide range of leads;

2) Small radial and axial dimensions of the nut;

3) High load capacity, high reliability, low noise, high speed.

c. Applications

CNC machine tools, industrial automation and intelligent manufacturing, automobiles (electric vehicles), aerospace, military, woodworking machinery, 3C equipment, transportation, glass processing, packaging machinery, modular machinery, etc.

Internal Circulation Ball Screw

a. Structure

An internal circulation ball screw consists of a screw, nut, balls, return mechanism, and sealing device. In the side holes of the nut, there is a return mechanism (or ball return device) connecting adjacent raceways. The ball return grooves on the return mechanism allow the balls to roll along the raceway, cross over the top of the screw thread raceway teeth, and return to the initial raceway, forming a circulating ball chain (i.e., a row).

b. Features

1) Suitable for small and medium leads;

2) For medium and low-speed applications;

3) Small nut outer diameter, suitable for minimum space installation.

c. Applications

CNC machine tools, industrial automation and intelligent manufacturing, automobiles (electric vehicles), aerospace, military, woodworking machinery, 3C equipment, transportation, glass processing, packaging machinery, modular machinery, etc.
