DINGS (controlled subsidiary of Jiangsu Leili) ball screw linear actuators in six frame sizes (14-57 mm), all external-drive, plus 28/42 DLG integrated rail-guided and DRS non-guided designs; 90-96% transmission efficiency (vs 26-70% for trapezoidal screws), 0.005-0.1 mm/step; C7 standard accuracy with C5/C3 options, Ф0.8 balls, SCM415H screw/nut at HRC58-62, rated dynamic 680-880 N / static 1200-1500 N, axial backlash ≤0.02 mm; optional encoders (to 1000/2000 resolution) and power-off brake (24 V, 5.5 W, >0.3 N·m holding, 2M-cycle life, <60 dB); for X-Y tables, medical devices, semiconductor and valve control.
Hengli ball screw assemblies span BHSK/KHSK heavy-load, BRP/BRS external-circulation, DWP/DWS internal-circulation and KRP end-cap series; shaft 16-140 mm, lead 4-80 mm, accuracy C0-C10, DN up to 160,000, for robotics, machine tools and injection molding linear drives.
Swiss Rollvis (since 1970) focuses on planetary roller screws: 3.5-210 mm shaft diameters, 1.0-50 mm leads and 3.9-3800 kN dynamic load ratings; the HRV heavy-duty series starts at 60 mm shafts with even higher load density for electro-mechanical replacement of hydraulics. Internal synchronizing gears with precision-ground shaft, rollers and nut give up to 15x ball-screw life, >40 in/sec speed and 3G acceleration; ISO 9001:2015 and EN 9100:2018 certified for robotic joints, prosthetics, injection molding and aerospace.
THK ball screws roll balls between shaft and nut for high efficiency: driving torque under one third of sliding screws, zero backlash, high rigidity, micro-feed and high-speed feed. The finished-shaft-end precision BNK04-BNK16 series covers screw shaft diameters 4-16 mm with leads 1-20 mm for precision positioning, alongside caged-ball, full-ball, rolled and rotary ball screw lines.
Ewellix (now Schaeffler Linear Motion) planetary roller screws use a non-recirculating planetary design for ultimate drive performance: official technical data — nominal diameter 8-240 mm, lead 2-50 mm, basic dynamic load capacity up to 3,994 kN, static up to 23,387 kN, n×d0 up to 160,000, acceleration up to 12,000 rad/s², linear speed up to 1.8 m/s; nut types SRC/BRC, SRF/BRF, SRP/BRP, preloaded split PRU/PRK and high-performance HRC/HRF/HRP.
