FAQ

What are the main advantages of a PTFE composite bearing?

The primary advantages are self-lubrication (no need for grease or oil), very low friction, high wear resistance, and a wide operating temperature range. They are also compact and lightweight.

Is this bearing suitable for high-temperature applications?

Yes, SKF PCM bearings have a continuous operating temperature range from -200 to +280 deg C (-390 to +535 deg F), making them suitable for a wide variety of demanding environments.

Can this bearing be used in a lubricated system?

While designed for dry operation, its performance can be enhanced in lubricated or grease-lubricated applications. The presence of a lubricant can further reduce friction and extend service life, especially in contaminated environments.
