697ZZ Round-Type POM Plastic Bearing Wheels

697ZZ Round-Type POM Plastic Bearing Wheels

⚙️Structural composition: This pulley is centered around a 697ZZ bearing. On both sides of the bearing, there are sealing covers (ZZ indicates double-sided sealing), which prevent dust and impurities from entering the bearing interior and ensure its normal operation. The outer ring of the bearing is coated with a wheel body made of POM (polyoxymethylene) material.

⚙️Size specification: The inner diameter of bearing 697ZZ is 7mm, the outer diameter is 17mm, and the thickness is 5mm. The size of the POM 697ZZ bearing pulley is 7x24x6mm.

⚙️Material properties: The POM material has an extremely low friction coefficient and excellent wear resistance, capable of withstanding long-term high-speed operation without deformation. Additionally, it has self-lubricating properties, reducing friction and wear without the need for external lubrication, thereby lowering maintenance costs. Moreover, the POM material exhibits good mechanical strength, fatigue resistance, and chemical resistance, being well-tolerated by most solvents and chemicals, and maintaining stable performance in humid environments.

⚙️Performance advantages: The POM round-type 697ZZ bearing pulley operates without noise and has a certain vibration absorption function, providing a smooth running experience. Its weight is lighter than that of metal pulleys, making it more suitable for the trend of modern lightweight design. The high-speed performance of the 697ZZ bearing combined with the wear resistance of the POM wheel body makes it suitable for various working scenarios.

⚙️Product Application:

This pulley is commonly used in 3D printers, power tools, food machinery, medical devices and other equipment. These fields have high requirements for the wear resistance, low noise and no lubrication needs of the pulley. The POM circular 697ZZ bearing pulley can well meet these requirements.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
