FAQ What does the ‘BTNG’ suffix in 3310BTNG stand for?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. Is this bearing suitable for high-temperature applications?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. What is the recommended lubrication for this bearing?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. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
