FAQ

Question?

What does the 'ET' suffix in NU315ET signify?

The 'E' indicates an optimized internal design for higher load capacity compared to standard bearings. The 'T' denotes a polyamide resin cage, which offers good performance in terms of low noise, low friction, and can operate at moderate temperatures.

Can this NU-type bearing handle axial loads?

No, the NU design with two ribs on the outer ring and a ribless inner ring is designed to accommodate high radial loads only. It allows for axial displacement between the shaft and housing, making it suitable for non-locating bearing positions.

What kind of lubrication is recommended for the NSK NU315ET?

This bearing can be lubricated with either grease or oil, depending on the application's speed, load, and operating temperature. For high-speed applications, oil lubrication is generally preferred. Always refer to your machinery's maintenance manual for specific lubricant requirements.
