Ball Screw Linear Actuators with V-Roller Guides
- Max Load (Fz): 980 N (220 lb)
- Max Load (Fx): 1,958 N (440 lb)
- Cross Section: 55 mm x 55 mm
- Stroke Lengths: 50 mm to 2,710 mm (107 in)
- Leads: 5 mm, 10 mm, 0.200 in
- Accuracy: ISO Class 10 standard; Class 7 and 5 available
- Max Speed: 2 m/s (79 in/s) at 1 in lead
- Guideways: Cam rollers on Integral-V hardened steel raceways
Ball screw driven linear actuators of the PLA Series feature pre-loaded ball bearing cam V-rollers on patent-pending Integral-V™ hardened steel v-groove raceways, encased in a robust 68 mm x 55 mm anodized aluminum housing that resists debris. Supporting a 220 lb (980 N) horizontal payload and up to 2,710 mm (107 in) stroke length, they excel in industrial automation and material handling. Major benefits include four T-slots for easy mounting and a magnetic stainless steel seal strip that effectively prevents contamination. Sensors and motor mounts can be ordered optionally via "Configure CAD and Quote" below each product.

* Max length and speed are limited by the critical speed of the screw. Max load is limited by the column strength of the screw. Values listed are theoretical maximums.
4 Fx applies to ball and acme screws only. Contact PBC Linear for lead screw values.
Moment arms for calculating moments should be measured from the centerline of the driveshaft. Limit switches must be used to prevent the carriage contacting the actuator end blocks.
