PBC Linear® manufactures linear actuators, including linear rails, shafts, carriages, bearings, screws, nuts, belts and other parts. The three primary drive mechanisms are Ball Screw Actuators, Lead Screw Actuators, and Belt Driven Actuators. We provide NEMA motors, motor mounts, or leave a stub for alternative energy sources. The motor size options are NEMA 8, 11, 14, 17, 23, 34 and 42.
In addition to the type of drive mechanism, linear actuators can be segmented by how the carriage or moving element operates, such as by a gliding slide on a rail, ball bearing profile rail, or via a flattop carriage on pillow block bearings gliding along shafts. Even further segmentation of Linear Actuators comes from the various screw diameter and lead sizes to choose from and from the choice of screw nut to use. There are cylindrical or flange nuts for ball screws and round or triangle nuts for lead screws with the further option of having Constant Force Anti-Backlash technology.
Three primary drive mechanisms:
- Ball Screw: the high end solution for heavy loads, precision and speed.
- Lead Screw: the cost effective solution with the best ability to lock in place
- Belt-Driven: Designed for high-speed applications with longer stroke lengths, offering low noise and smooth operation. They are ideal for tasks that require rapid positioning over extended distances.
Because of our closeness to many separate industries, our range now includes miniature linear actuators as small as 28 mm x 32 mm for space-constrained applications, heavy-duty actuators supporting loads up to 11,200 N, belt-driven actuators with stroke lengths as high as 6 meters, and high-speed actuators for rapid positioning tasks.
