Linear Motion Product Lines
Four essential linear motion component categories — sourced across all 8 partner brands with full technical parameter comparison and cross-brand interchange support.
1. LM Guide Rails & Blocks
Linear Motion (LM) guides are the backbone of precision automation. Available in ball-type and roller-type configurations, with standard, wide, miniature, and heavy-duty profiles. Covered seals, scrapers, and lubrication options are configurable per application.
| Series | Brand | Type | Rail Width (mm) | Dynamic Load (kN) | Best For |
|---|---|---|---|---|---|
| HSR | THK | Ball | 15–85 | 8.5–326 | General automation |
| SHS | THK | Ball | 15–65 | 14–215 | High-speed positioning |
| HG | HIWIN | Ball | 15–65 | 11.3–199 | 3C / lithium battery automation |
| EG | HIWIN | Ball | 15–35 | 5.5–40 | Compact, cost-effective |
| MSA | PMI | Ball | 15–45 | 7.5–127 | CNC machine tools |
| Rexroth RBS | Bosch Rexroth | Roller | 25–125 | 58–524 | Heavy machinery |
| MINIRAIL | Schneeberger | Ball | 7–25 | 1.2–12 | Semiconductor / medical |
2. Ball Screw & Nut Assemblies
Precision-ground and rolled ball screws from C0 to C7 accuracy grades (JIS B 1192). Preloaded nut configurations available for zero-backlash applications. Self-lubricating variants from TBI MOTION for cleanroom and food-grade environments.
| Series | Brand | Diameter (mm) | Lead (mm) | Accuracy | Special Feature |
|---|---|---|---|---|---|
| BNK | THK | 6–50 | 1–20 | C0–C5 | Precision ground |
| BIF | THK | 8–40 | 2–10 | C3–C7 | Compact nut design |
| Super S | HIWIN | 8–63 | 2–25 | C3–C5 | High-speed capable |
| SFI | TBI MOTION | 8–50 | 4–20 | C5–C7 | Self-lubricating |
| NSK BSS | NSK | 6–32 | 1–16 | C0–C3 | Ultra-low noise |
3. Precision Support Bearings
Angular contact bearings, crossed roller bearings (THK RB/RA series), and deep-groove bearings configured for ball screw support applications. High axial rigidity with low runout. Matched pairs available for fixed-floating end arrangements.
4. Miniature Linear Modules
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 applications. Stroke lengths from 30 mm to 1,200 mm.
