Trapezoidal Thread Screw

SCREWTECH manufactures not only Ball Screws but also Precision Lead Screws. It can be used as small Pitch which Ball Screw do not have, and it can be achievable when less precise products are needed. Precision lead screws are an excellent economical solution for your linear motion system.

Features of SCREWTECH Precision Lead Screw

Possible to select small pitch. It is possible to select small Pitch which Ball Screws do not have.

Wide variety of size

Metric Fine Thread and Metric Coarse Thread based on JIS(Japanese Industry Standard) are standardized but we also manufacture Trapezoidal Thread, Unified Screw Thread, ACME Screw Thread, special Pitch, and multiple start Thread. 

Low torque

With knowhow of screw gauge, we make sure use of grinding technique, and lapping technique, so fine surface roughness and low wobble become reality, which lead low torque and less wear. 

Flexibility of Nut configuration

Nut configuration is not restricted and it is possible to manufacture in accordance with customer's design. 

Bi-directional Lead Screws

Bi-directional Lead Screw which are machined Left handed and Right handed thread on a Shaft, and Nuts are mounted on each thread. Both Right and Left Nuts move symmetrically, precise positioning, and width adjustment by single motor. Nut configuration is designed freely to suit customer's requirements.
