What is the Needle Roller & Cage Assembly?

The K Series (such as K588TN) represents the most basic yet efficient form of needle bearing. This assembly consists of a precisely guided cage and a set of needle rollers. Because it has no inner or outer rings, the shaft and the housing bore serve as the actual raceways. This series provides the smallest possible radial envelope for any rolling-element bearing.

Key Advantages & Features

• Minimal Radial Space: Eliminates the thickness of bearing rings, using the machine's existing components.

• High Rotational Accuracy: Precise cage guidance ensures smooth operation even under high-speed oscillation.

• Easy Installation: Designed for simple drop-in assembly between the shaft and housing.

Application Areas

Extensively used in motorcycle engines (connecting rod big/small ends), automotive gearboxes, and planetary gears.

Solutions Provided

For engineers designing high-performance gear systems where every millimeter of space counts, the K Series provides a robust radial support solution without adding the bulk of a traditional bearing.
