• Worm Gear Wheel and Worm Gear Shaft are sold separately on this link！Therefore, if you want to use them in pairs, you will need to purchase the worm gear wheel and worm shaft separately.
• Worm gear wheel and worm gear shaft can only be used in pairs if they are of the same gear module.
• Module is the model, on behalf of the size of the gear teeth. The larger the module, the larger the teeth, the more force they can withstand.
• Please use the drop down menu to select your required number of teeth and bore size.
• Bore options are not marked keyway size, the default is through-hole, there are marked keyway size is the keyway hole, attention to distinguish between the purchase.
• Stainless steel is just not easy to rust steel, does not mean that it will not rust, the higher the grade of stainless steel, the less likely to rust, the gear sold in this link are 304 stainless steel.
• Individual gear surface has a little floating rust, just in the production of some iron slag, oil residue and so on did not clean up in time to cause the surface to produce a similar state of rust, such surface marks can be wiped off on the surface and are not a quality issue.
• If you need other sizes, shapes and quantity , you can also contact us to support custom. Professional equipment processing.

The advantages of stainless steel gears include corrosion resistance, high strength, wear resistance, good mechanical properties and environmental health.

Corrosion resistance. Stainless steel materials have good corrosion resistance and can be used in a wide range of chemical media environments, which makes stainless steel gears particularly suitable for high humidity and strong corrosive working conditions.

High strength and wear resistance. Stainless steel has high strength and wear resistance, which can withstand high loads and reduce gear wear for a long time.

Good mechanical properties. Stainless steel gears have excellent mechanical properties, including tensile strength, elongation, hardness and wear resistance, which makes stainless steel gears suitable for high-speed, high-torque, long-life and low-noise transmission applications.

Environmentally friendly and healthy. Stainless steel material is non-toxic, odourless, non-polluting, in line with the requirements of environmental health, the use of stainless steel materials to make gears can be avoided in the traditional materials containing lead, mercury, chromium and other harmful substances released.

All purchased gears are delivered with grub screws .
