FAQ

What does the ‘TNG’ suffix signify in the NSK 1203TNG bearing?

The ‘TNG’ suffix in NSK bearings typically denotes a glass-fibre reinforced polyamide 6.6 cage. This type of cage is lightweight, offers excellent sliding properties, and is suitable for high-speed applications.

What is the main advantage of a self-aligning ball bearing?

The primary advantage is its ability to accommodate static and dynamic misalignment. The outer ring has a spherical raceway, allowing the inner ring, balls, and cage assembly to rotate freely around the bearing center, compensating for shaft deflection or housing alignment errors.

Is this bearing suitable for high-temperature applications?

The polyamide cage (TNG) has a maximum continuous operating temperature of around 120 deg C. For applications exceeding this temperature, a bearing with a steel or brass cage (e.g., suffix M) would be a more suitable choice.
