Shibaura Machine BA-III Single Axis Review: Specs and Uses of the Single-Axis Cartesian Robots
Updated: 7 days ago

The Shibaura Machine COMPO ARM BA-III single-axis range provides building blocks for cartesian robots. The manufacturer does not publish a price. This review covers its specifications, features and uses.
Quick Verdict
The BA-III range covers almost every single-axis need in one family. Small ball screw and pushrod modules carry 4 to 30 kg at ±0.02 mm. Medium ball screw units such as the BA3-10 and BA3-30 carry up to 100 kg at ±0.01 mm over 1,250 mm, while belt versions reach 3,500 mm at 2,000 mm/s. The heavy BA3-60 carries up to 250 kg horizontally at 2,300 mm/s, and heavy belt versions reach 4,450 mm. Rotary modules with harmonic or planetary gears complete the set. Payload and speed depend on lead and stroke, and one stroke note on the maker's page appears to be an error.

Shibaura Machine BA-III Single Axis Technical Specifications
The table below lists what the manufacturer states.
Model | Drive | Stroke | Horizontal payload | Max speed | Repeatability |
BA3-T5D / T7D | Ball screw | 50 to 700 mm | 5 to 30 kg | 800 mm/s | ±0.02 mm |
BA3-T3D / T4D / T5E | Ball screw, pushrod | 50 to 300 mm | 4 to 25 kg | 600 mm/s | ±0.02 mm |
BA3-10 / BA3-30 | Ball screw | 100 to 1,250 mm | 20 to 100 kg | 1,200 mm/s | ±0.01 mm |
BA3-10 / 30 / 50 | Timing belt | 100 to 3,500 mm | 15 to 40 kg | 2,000 mm/s | ±0.04 mm |
BA3-50 | Ball screw | 200 to 1,600 mm | 60 to 150 kg | 1,200 mm/s | ±0.01 mm |
BA3-60 | Ball screw | 150 to 1,700 mm | 25 to 250 kg | 2,300 mm/s | ±0.01 mm |
BA3-50 / 60 | Timing belt | 150 to 4,450 mm | 100 to 200 kg | 1,000 mm/s | ±0.05 mm |
BA3-00D-RH / RP | Harmonic / planetary rotary | Rotary | 10 kg | 360 / 857 °/s | ±0.025 / ±0.125° |
Payload and speed depend on lead, stroke and motor output. The page's note of a 42 mm maximum stroke for the BA3-10 belt version conflicts with its 100 to 2,550 mm range.
