Discover more about the Rack Gauges range.

Rack gauges are precision tools designed to align multiple rack gears by ensuring uniform tooth spacing across all components. By matching the gear teeth along adjacent racks, these gauges are essential in assemblies where uninterrupted linear motion is critical.

For example, in large mechanical systems or CNC platforms where multiple rack sections must operate as a single unit, rack gauges provide the necessary accuracy for seamless engagement.

How Rack Gauges Work

Rack Gauges function by acting as a reference template. During installation, the gauge is placed between two adjacent rack sections to verify that the teeth are perfectly aligned. This eliminates errors caused by cumulative tooth pitch misalignments, which can otherwise lead to increased wear, backlash or failure in precision motion systems. Their ease of use makes them a necessary tool in aligning multiple racks.

Materials Rack Gauges Are Made From

At Accu, our rack gauges are crafted from robust materials chosen for their longevity and resistance to wear in both workshop and field environments.

Carbon Steel: Offers a good balance of hardness and durability for regular use.
Chromium-Molybdenum Steel: Provides enhanced strength and resistance to corrosion, ideal for prolonged toolcase storage or demanding environments.

Sizes and Types of Rack Gauges Available

Our selection of rack gauges is available in a range of module sizes and face widths to suit various gear setups:

Module Sizes: From 0.5MOD to 3MOD, accommodating fine to medium gear teeth.
Face Widths: Options from 8mm (h8) to 30mm (h8) ensure compatibility with a broad range of rack gear profiles.

FAQs

Q: What is the purpose of a rack gauge?

A rack gauge ensures that the teeth of multiple rack gears are correctly aligned, enabling smooth and consistent linear motion of a pinion gear across joined sections.

Q: Can rack gauges be reused?

Yes, rack gauges are reusable precision tools made from durable materials, suitable for repeated use in both workshop and installation settings.

Q: Are rack gauges compatible with all rack gears?

Our gauges are compatible within the specified module (MOD) and face width ranges. Always check the product's specifications to ensure proper fit for your gear system.
