## Features

- Ball screw drive mechanism – precision ball screw technology for smooth, efficient linear motion with minimal backlash
- Paired with SCU6x controller – BLA-015 and BLA-030 use SCU6x MD; BLA-067 uses SCU6x MxD for higher current demand
- Front and rear spherical bearing mounting – accommodates misalignment and angular deflection, reducing side loading on the ball screw
- BLA-015-0600-TG – 150 lbf thrust, 6 in stroke, 4 A at 24 VDC for light terminal guides and slitter carriages
- BLA-030-0600-TG – 300 lbf thrust, 6 in stroke, 4 A at 24 VDC for medium-load coating heads and shifting stands
- BLA-067-0600-TG – up to 650 lbf thrust, 6 in stroke, 6 A at 24/48 VDC for maximum BLA capacity terminal applications
- Load capacity up to 10,000 lb – with precision linear bearings (5,000 lb with standard bearings)

## Benefits

- Stop overpaying for oversized actuators – the BLA Series is purpose-built for low-to-medium load applications, delivering up to 650 lbf of thrust at a fraction of the cost and complexity of larger systems
- Handle loads up to 10,000 lb – with precision linear bearings, BLA actuators support web roll loads for most slitter carriages, coating heads, and light shifting stands
- Eliminate custom engineering – three standard models cover the most common low-to-medium load terminal guide applications; order, bolt in, wire up
- Drop in with zero frame modifications – pivot, rod eye, and clevis mounting options match existing frame geometries for pneumatic cylinder or worn actuator replacement

## Applications

- Slitter carriages — precise lateral positioning for slitter knife assemblies
- Coating heads — accurate alignment of coating applicators across the web
- Light shifting stands — lateral shifting of rolls and stands up to 10,000 lb
- Low-to-medium load terminal guides for winders and rewinders handling moderate roll weights
