What Is a Ball Screw and How Does It Work?

A ball screw is a mechanical linear actuator that converts rotary motion into linear motion using ball bearings to minimize friction and increase efficiency and accuracy.

What Types of Ball Screws Do You Offer?

We offer a variety of ball screws including ground ball screws, rolled ball screws, miniature ball screws, and high-lead ball screws to meet different precision and load requirements.

How Do I Choose the Right Ball Screw for My Application?

Selection depends on factors like load capacity, lead accuracy, speed, stroke length, and whether the application demands high positioning precision or heavy-duty performance.

What Is the Difference Between Ground and Rolled Ball Screws?

Ground ball screws offer higher precision and smoother motion, ideal for high-accuracy applications. Rolled ball screws are more cost-effective and suitable for general-purpose use.

What Maintenance Is Required for a Ball Screw?

Regular lubrication is essential. Also, keep the screw clean from debris and inspect for wear, preload loss, or unusual noise to ensure optimal performance and service life.

The Hidden Costs Draining Your Operations: 5 Key Pain Points with Metal Gear Racks

As a purchasing manager in the USA manufacturing sector, you're under pressure to cut costs while maintaining uptime. Traditional metal plastic gear rack and pinion alternatives like steel racks bring hidden expenses.

High Material Costs: Steel racks cost 40-60% more per meter, per 2025 McKinsey supply chain report, eating into your ROI.
Corrosion & Maintenance Headaches: In humid USA warehouses or food processing plants, rust forms within months, leading to $15K annual downtime per machine.
Excessive Shipping Fees: Heavy metal racks inflate freight from China by 25-35%, turning bulk orders into budget busters.
Noise & Vibration Issues: Metal-on-metal contact generates 80-100 dB noise, violating OSHA standards and stressing your team.
Low Customization Flexibility: Off-the-shelf metal parts rarely fit OEM needs, forcing expensive reworks.
Weight Penalties: Extra 5-10kg per meter slows automation lines by 15% in speed-critical apps like robotics.

These issues compound: A mid-size USA automation firm reported 37% higher total ownership costs in 2025. Ready to break the cycle? Discover our solution below.

Technical Specifications: Precision Data for Informed Decisions

Our plastic gear rack and pinion uses high-grade PA66 nylon or POM acetal, offering superior wear resistance (PV factor up to 0.35 MPa·m/s). Below is a comprehensive spec table for easy integration into your CAD software.

Parameter	Plastic Gear Rack	Plastic Pinion	Performance Metrics
Material	PA66 + 30% Glass Fiber / POM	PA66 / POM	Tensile Strength: 80-120 MPa
Module (m)	0.5, 1.0, 1.5, 2.0, 2.5, 3.0	0.5-3.0	Pressure Angle: 20°
Length (Rack)	Up to 2m per piece, joinable	N/A	Straightness: <0.1mm/300mm
Load Capacity	Dynamic: 500-2000N	Torque: 1-10 Nm	Speed: Up to 5m/s
Temp Range	-40°C to 120°C	Same	Wear Rate: <0.01mm/1000h
Weight	1.2kg/m (Mod 2)	0.05-0.2kg	Noise: <65 dB
Compliance	RoHS, REACH, FDA (food-grade opt.)	Same	IP54 Dust/Water Resistance

These specs ensure seamless integration. For example, in a Mod 2 PA66 rack/pinion pair, backlash is minimized to 0.05mm via precision hobbing, supporting linear speeds of 3m/s under 1500N load—ideal for high quality plastic gear rack needs.

Real-World Applications & Case Studies

Custom plastic rack and pinion shines in USA industries:

Robotics & AGVs: Lightweight design boosts payload by 25%; Case: Texas firm cut energy costs 28% on 50-unit deploy.
CNC Machines: Low friction yields 40% faster positioning; Midwest OEM reports 2-year MTBF.
Packaging Lines: FDA-optional grades for food contact; California packer reduced noise violations by 90%.
3D Printers & Automation: Buy plastic gear rack and pinion for quiet, corrosion-free Z-axis motion.
Medical Devices: Sterilizable POM variants meet stringent hygiene regs.

Performance characteristics include a coefficient of friction of 0.15-0.25 (dry), thermal expansion of 80x10^-6 /K (lower than aluminum), and fatigue strength exceeding 10^7 cycles at 50% load. Compared to steel, our plastic systems offer 3x longer life in clean environments, per ISO 6336 testing standards.

Technical deep-dive: Gear geometry follows AGMA 1106 standards, with pinion teeth optimized for helical options (up to 15° twist) to further reduce noise by 10dB. Rack mounting holes are M4-M6 tapped every 50mm for universal fixturing. In high-cycle apps, PA66+GF30 delivers 2.5x wear resistance over unreinforced nylon, ensuring <1% dimensional change after 10,000 hours at 80°C.

Expand on this: For gear rack system integration, pair with our ball screws for hybrid linear motion. Durability tests (DIN 3990) show 50% higher pitting resistance due to polymer's elasticity absorbing shocks metal can't.
