High-precision, low-friction transmission for robot joints, end-effectors and 7th-axis linear units - ball screws, linear guides, ball splines and single-axis robots.
Industrial robots (six-axis articulated, SCARA, Delta, Cartesian gantry, cobots) are the core of smart manufacturing. Joint drives, end-effectors and the 7th axis demand high precision, rigidity, response and reliability. Key metrics: repeatability ±0.02mm to ±0.1mm (by load and class); joint response ≥ 50Hz; noise ≤ 65dB; MTBF ≥ 50,000 hours; 24/7 operation.
For different robot applications, Shiyi Automation supplies:
High-rigidity design (high-assembly square blocks, heavy-load SFVR screws, rigid fixed-side supports for high-speed start-stop and heavy load); low friction (precision-ground screws, high-precision rolling elements and suitable preload for low noise and long life); high response (small-lead screws for resolution, rigid couplings for response frequency); and reliability (every part life-calculated and verified for MTBF ≥ 50,000 hours).
A Guangzhou auto-parts OEM built an engine-block machining line with six six-axis robots on a 7th axis: 12m stroke, 2000kg load (robot + workpiece), 1m/s, ±0.1mm. Solution: two TRH35 rails (4 blocks each, 8 total) + SFVR4010 screw (C5, preload P1) + BK30/BF30 supports + rack-and-pinion assist drive. Results: ±0.08mm positioning, ±0.05mm repeatability, noise ≤ 62dB, 12 months fault-free, calculated life 80,000 hours.
End-to-end support from design and supply through installation to maintenance, with a team experienced in robot transmission systems - workcell drive design, 7th-axis installation guidance, Cartesian robot selection and configuration, and spares supply.
