Plastic Gear Rack

Plastic gear racks are made of plastic, a lightweight and durable material. They are often used in applications where metal gears would be too heavy or expensive. Plastic gear racks are also less likely to corrode than metal gears, making them a good choice for outdoor applications.

Plastic gear racks are typically made of nylon or acetal plastic. Nylon is a strong and durable material that is resistant to wear and tear. Acetal plastic is a high-performance material that is resistant to heat and chemicals.

Plastic gear racks are available in a variety of shapes and sizes. They can be used to transmit power from one component to another, or they can be used to convert rotary motion into linear motion.

Plastic gear racks are a versatile and cost-effective solution for various applications. They are easy to install and maintain and offer a long life.

Here are some of the benefits of using plastic gear racks:

• Lightweight and durable
• Resistant to corrosion
• Cost-effective
• Versatile
• Easy to install and maintain
• Long life

If you are considering using plastic gear racks in your application, there are a few things you should keep in mind:

• The type of plastic gear rack you choose will depend on the load and speed of your application.
• You will need to select the right plastic gear rack for the motor you are using.
• You will need to install the plastic gear rack properly.

Standard Materials of Nylon Gear Rack and Pinion

• PA6 PA66: suitable for medium or low load, under 80°C temperature, working under low or no lubrication conditions.
•  PA610.PA9 and PA1010: the same as above; they can work under moderate fluctuations.
•  Cast nylon: suitable for the manufacture of giant gears.
•  Reinforced nylon: suitable for high load and high-temperature applications, high transmission efficiency, and lubricating oil should be added during operation.
•  PC: lubrication should be added when running at high speed.
•  Modified polyphenylene ether: precision gears that can be used in hot water or steam
•  Polyimide: gear suitable for long-term operation at 260°C
•  Reinforced polyester: ideal for high or medium and low load, working under 150°C, under lubricating conditions
•  Polyphenylene sulfide: suitable for gears with medium and high loads and no lubrication
•  UHMWPE: ideal for medium and low bag, oil-lubricated gears below 240 degrees
•  Cloth phenolic: ideal for low load gears

Flexible Plastic Gear Rack

Flexible plastic racks and pinions are used in turntables, linear actuators, etc. These racks are made from 12 to 16-tooth drive gears and are molded from a durable and flexible plastic material. In addition to being flexible, these racks are designed to be highly accurate and repeatable.

Flexible plastic rack and pinion available in 0.8 Mod and 32DP pitch for easy rotational drive up to 270 degrees. They are also commonly used in camera focus rings. The flexible plastic rack and pinion allow longer stretches for linear motion, making it an ideal solution for more giant gears.

While polyacetal is the industry standard, polyketone is a less expensive alternative. Its low coefficient of friction and high hardness grade make it an ideal material for racks and pinions. Polyketone gears have excellent hardness levels, higher safety against tooth breakage, and extremely high wear resistance. Its tribological properties are also impressive. Because plastic racks are not straight, the actual length is a multiple of the pitch.
