Are Plastic Gear Racks Resistant to Oils and Greases?

Plastic Gear Rack is a type of rack made of plastic, used to transmit power and motion. This article delves into the characteristics, advantages, applications, installation, maintenance, and selection of plastic gear racks, with a special focus on their resistance to oils and greases.

Structure and Materials

Composition of Plastic Rack

The basic structure of a Plastic Gear Rack consists of a series of teeth and gaps arranged in a linear fashion. These teeth mesh with a gear wheel, facilitating the conversion of rotational motion into linear motion or vice versa. The design and profile of the teeth are crucial for efficient force transmission and motion.

Commonly Used Plastic Materials

Plastic gear racks can be made from various plastic materials, including:

  • Polyamide (PA)
  • Polyethylene (PE)
  • Polypropylene (PP)
