LINEAR ACTUATOR TECHNOLOGY PL Series PLA Ball Screw Driven Linear Actuator SIMULTANEOUS INTEGRAL MILLING OPERATION Hardened Steel V-Raceway FEATURES & BENEFITS TECHNICAL DATA • High Speed Cam Roller Design - Pre-loaded ball bearing cam rollers are guided by the patent pending Integral V™ hardened steel raceways. Creates smooth precision guidance • Ball, Acme or Lead Screw Driven - high positioning accuracy and high load/torque load requirements • SIMO® - (Simultaneous Integral Milling Operation) patent pending machining process for precision machined surfaces on all housing sides • Accessories: couplings, mounting clamps, motor mounts, limit switches, gear reducers, shaft extensions etc. Base Weight Key Features (1) Positioning accuracy assured by ball or lead screw drive (2) Double row angular contact bearing (3) T-slots for easy mounting 1 (4) Seal strip - stainless steel, magnetically sealed NOTE: 1. Moment arms for calculating moments should be measured from the centerline of the driveshaft. 2. Limit switches must be used in order to prevent the carriage from contacting the actuator end blocks, resulting in damage. 3. 25mm of over-travel has been added to the body length in each direction to allow for carriage over-travel. 25mm is the recommended over-travel; although a minimum of 10mm may be specified for special applications. 4. Fx applies to ball and acme screws only. Contact manufacturer for lead screw values. *Max length and speed are limited by critical speed of screw. Max load is limited by column strength of screw. Values listed are theoretical max. Max. Radial Load on Input Shaft 2 For combined loads, the combined loading cannot exceed the following formula.

DIMENSIONAL INFORMATION LOAD RANGE (Ball & Acme Screws) BODY LENGTH = STROKE + CARRIAGE LENGTH + (2 X OVERTRAVEL) (SELF-LOCKING HELICOIL) OPTIONAL DUAL CARRIAGE -OVERALL LENGTH = BODY LENGTH + DRIVE END LENGTH + IDLER END LENGTH-*- (SELF-LOCKING HELICOIL) The recommended operating range is below and to the left of the shown curves. Speeds indicated by the curves are based upon 80% of the critical speed of the ball screw. Higher recommended speed ranges can be achieved by selecting a larger lead ball screw.
