FAQ

What does the ‘CM’ suffix signify in the NSK 6315CM?

The ‘CM’ suffix in NSK bearings denotes a specific internal clearance and cage design optimized for electric motor applications. It ensures low noise and low vibration performance, which is crucial for the smooth operation of motors.

Is this bearing suitable for high-temperature applications?

As an open bearing with a brass cage, the 6315CM can handle higher operating temperatures than bearings with rubber seals or polyamide cages. However, the maximum temperature is limited by the lubricant used. Always ensure the grease or oil is rated for your specific application’s temperature range.

What type of lubrication is recommended for an open bearing like the 6315CM?

The choice of lubrication depends on the application’s speed, load, and temperature. For general use, a high-quality lithium-based grease is common. For high-speed applications, oil lubrication (drip, mist, or bath) might be necessary. It is crucial to consult your machine’s maintenance manual for the correct lubricant type and relubrication intervals.
