Power Transmission

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Stepper Motors

The motor shaft turns in small, equal increments for precise positioning

Electric Actuators

Electric Actuators

Push and pull loads with more precise positioning than air and hydraulic cylinders

Ball Screws and Nuts

Ball Screws and Nuts

Provide smooth travel where high speeds, accurate positioning, and repeatable movement are required

Ball Screw/Splines and Bearings

Ball Screw/Splines and Bearings

Transmit rotary power, move loads along the shaft, or do both at once

Roller Screws and Nuts

Roller Screws and Nuts

Create more points of contact to handle much higher loads than ball screws and nuts of the same size

Material Handling

Jacks

Lift, hold, push, and position heavy objects
