Four essential linear motion component categories — sourced across all 8 partner brands with full technical parameter comparison.
Linear Motion (LM) guides in ball-type and roller-type configurations. Available in standard, wide, miniature, and heavy-duty profiles. Covered seals, scrapers, and lubrication options configurable per application. Compatible across THK, HIWIN, PMI, Bosch Rexroth, and more.
Precision-ground and rolled ball screws in C0–C7 accuracy grades. Preloaded nut configurations for zero-backlash applications. Self-lubricating variants from TBI MOTION for cleanroom and food-grade environments.
Lead: 1 mm – 40 mm; Diameter: 6 mm – 100 mm.
Angular contact bearings, crossed roller bearings (THK RB/RA series), and deep-groove bearings configured for ball screw support. High axial rigidity, low runout. Matched pairs available for fixed-floating end arrangements.
Integrated linear actuator units combining guide rail, ball screw, and motor mount in a compact footprint. THK KR series and HIWIN KK modules are popular choices for lab automation, pick & place, and desktop CNC.
Reduce supply chain risk by identifying compatible alternatives. Our engineering team validates preload, accuracy, mounting dimensions, and dynamic load ratings before recommending substitutions.
| Scenario | Primary Brand | Alternative Brand | Notes |
|---|---|---|---|
| Heavy-load, high-rigidity | THK | Bosch Rexroth | Cross-evaluate mounting hole pitch and rail width; both excel in dynamic load capacity above 100 kN |
| Standard automation guide | THK | HIWIN | Many form factors are directly interchangeable; verify preload class and accuracy grade before swapping |
| High-speed, low-noise | NSK | HIWIN (HG series) | Check vibration specifications; NSK typically offers lower noise floor in micro-feed applications |
| Miniature, ultra-precision | Schneeberger | Not recommended | For nanometer-level accuracy applications, cross-brand substitution is strongly discouraged; stick to OEM-specified components |
| Cleanroom, maintenance-free | TBI MOTION | THK (low-dust seal configuration) | TBI's self-lubricating technology eliminates grease leakage risk; THK low-dust seals suit Class 100 environments |
| Cost-optimized CNC | PMI | HIWIN | Both offer C3/C5 grade ball screws; compare lead accuracy charts for the specific stroke length |
