Trapezoidal Screws

The trapezoidal thread form is a common leadscrew thread profile that offers high strength with ease of manufacture.

It is typically found where large loads or high accuracy are required, as in a vise or the lead screw of a lathe.

Standardized variations include multiple-start threads, left-hand threads, and self-centering threads which are less likely to bind under lateral forces. The thread angle is 30°.

• D= 10 – 80 mm
• pitch: 2 – 24 mm
• Lmax: 6000 mm

Motorised Lead Screws

Motorised Lead Screws from Thomson combine a hybrid stepper motor and a precision lead screw together in one compact envelope. Patent-pending Taper-Lock technology allows quick decoupling and secure, properly aligned connections. Thomson Motorised Lead Screws come in two basic configurations – rotating screw (S) and rotating nut (N).

Rotating screw assemblies actuate by having the motor rotate a lead screw and translate a load that is attached to the lead nut. Rotating nut assemblies actuate by rotating a nut within the motor body. Motion is achieved by constraining the motor and translating a load attached to the lead screw or constraining the lead screw and translating a load attached to the motor.
