FAQ

The suffix denotes specific features of the bearing. 'B' indicates a 30-degree contact angle. 'TN' specifies a polyamide cage, which is lightweight and suitable for high speeds. 'G' stands for universal matching, meaning it can be mounted in pairs without special ordering.

The polyamide (TN) cage has a continuous operating temperature limit of approximately 120 deg C. For applications exceeding this temperature, a bearing with a steel cage would be more appropriate.

The NSK 3310BTNG can be lubricated with either grease or oil. The choice depends on the operating speed, temperature, and load. For most general applications, a high-quality lithium-based grease is sufficient.
