Important Notes

• Gears/pinions are sold separately and are not included with this rack. Ensure your pinion gear matches the modulus of the rack you select.
• The modulus determines tooth size — always pair racks and pinions of the same modulus for proper engagement.
• Standard (no-hole) racks are not designed for end-to-end splicing without additional machining. Contact us if you require spliced configurations.
• Packing: Plastic bag or carton box depending on size and quantity ordered.

Applications

These gear racks are ideal for a wide variety of mechanical and industrial uses, including:

• CNC router machines and linear actuators
• Automation and conveyor systems
• Robotic arms and slide mechanisms
• Gate opening systems and rack-and-pinion drives
• Machine tool tables and positioning stages

Frequently Asked Questions

Q: What modulus size should I choose for my gear rack application?

A: The modulus defines the size of the gear teeth. A 1M (Module 1) rack has smaller teeth suited for light-duty or precision applications, while 2M offers larger, stronger teeth for heavier loads. Always match the modulus of the gear rack with the pinion gear you are using — mismatched modulus gears will not mesh correctly.

Q: Are the pinion gears included with this stainless steel gear rack?

A: No, pinion gears are not included and must be purchased separately. Make sure to select a pinion with the same modulus (1M, 1.5M, or 2M) as the rack for proper engagement and smooth operation.

Q: Can these gear racks be spliced together for longer runs?

A: The standard no-hole rack is not designed for direct splicing without additional machining. If you need a longer continuous rack assembly, please reach out for custom machining options or to discuss splicing configurations.

Q: What cross-section size should I select?

A: The cross-section (width × height) you need depends on the load requirements and mounting constraints of your system. Common choices like 10×10mm suit lighter applications, while 20×20mm is appropriate for heavier structural or industrial drive systems.
