NSK NU214ET

NSK NU214ET Cylindrical Roller Bearing

Description

The NSK NU214ET is a high-performance single-row cylindrical roller bearing designed for superior radial load capacity and high-speed operation. Its NU design features two integral flanges on the outer ring and a flangeless inner ring, allowing for axial displacement of the shaft relative to the housing. This makes it an ideal non-locating bearing in industrial applications such as gearboxes, pumps, and electric motors.

FAQ

What does the ‘ET’ suffix signify in the NSK NU214ET bearing?

The ‘E’ suffix in NSK bearings typically indicates an optimized internal design for ‘Extra’ or ‘Enhanced’ load capacity compared to standard designs. The ‘T’ suffix refers to the cage material, which in this case is a molded polyamide (PA66) resin cage, known for its good sliding properties and suitability for high-speed applications.

Can this NU214ET bearing accommodate axial loads?

No, the NU design is a non-locating bearing. It has two flanges on the outer ring and a flangeless inner ring. This configuration allows it to accommodate axial displacement of the shaft relative to the housing in both directions, but it cannot support any axial load. For axial load support, it must be used in conjunction with a locating bearing, such as an NUP type or an angular contact bearing.

What type of lubrication is recommended for the NU214ET?

The appropriate lubrication depends on the operating speed, load, and temperature of the application. Both grease and oil lubrication are suitable for the NSK NU214ET. For general-purpose applications, a high-quality lithium-based grease is common. For very high-speed or high-temperature operations, a circulating oil lubrication system may be required to provide adequate cooling and lubrication. Always consult your machinery’s maintenance manual for specific recommendations.
