YF Gear designs and manufactures Spur Gear Racks engineered for consistent performance, precise linear movement, and long service life.
Built for CNC machines, automation lines, packaging systems, and door mechanisms, our racks convert rotary motion into accurate linear displacement through direct gear-to-rack engagement.
With high machining precision, induction-hardened teeth, and strict straightness control, YF Gear ensures low-backlash motion and stable power transmission across all applications.

1. Straightforward Design & Low Cost
Spur racks are ideal for projects where simplicity and cost efficiency are priorities.
The teeth are cut parallel to the rack axis, allowing direct, precise transmission without complex adjustments.
2. High Positional Accuracy
With tight pitch tolerances, our racks enable repeatable motion accuracy under continuous load — ideal for robotics and automation.
3. Robust Load Capacity
Carburized alloy steel construction ensures durability under heavy load or shock conditions.
4. Easy Integration with Standard Gears
All modules follow international gear standards (DIN / ISO), compatible with pinions from global brands.
| Aspect | Spur Gear Rack | Helical Gear Rack |
|---|---|---|
| Tooth Angle | 0° (Straight) | 15°–30° Helix |
| Efficiency | Higher (less sliding) | Slightly lower |
| Noise Level | Moderate | Lower (smoother engagement) |
| Load Capacity | High | Higher due to larger contact area |
| Axial Force | None | Generates axial thrust |
| Machining Cost | Lower | Slightly higher |
| Applications | General machinery, doors, conveyors | Robotics, automation, high-speed drives |
Quick Tip:
Use Spur Racks when compact structure and cost efficiency are key.
Choose Helical Racks when your design prioritizes smoothness and silence.
Spur Gear Racks play a fundamental role in mechanical systems requiring reliable, bidirectional linear motion.
CNC Equipment: For X/Y-axis linear drive and gantry motion

| Step | Key Recommendation |
|---|---|
| Alignment | Mount rack on a flat, rigid base; use gauge blocks for straightness check |
| Pinion Setup | Maintain 0.03–0.1 mm backlash to ensure smooth operation |
| Lubrication | Apply EP grease every 500–800 operating hours |
| Inspection | Check tooth wear and parallelism every 6 months |
| Replacement | Replace rack sections when backlash exceeds 0.3 mm |
| Challenge | Customer Concern | YF Gear Solution |
|---|---|---|
| Backlash Control | Precision in repetitive motion | Ground tooth flanks, DIN6 accuracy |
| Heavy Load Use | Impact & fatigue resistance | 20CrMnTi carburized steel |
| Corrosion Environment | Moisture or outdoor use | Zinc-plated / stainless options |
| Noise Reduction | Quiet operation in automation | Optimized tooth geometry & surface finish |
| Customization | Special length / module / hole layout | Full CAD-based custom manufacturing |
