NA (with the suffix "NA") and RNA (with the prefix "RNA") needle roller bearings with machined rings are types of bearings designed to accommodate high radial loads while maintaining a small axial footprint.

NA, RNA needle roller bearings are particularly well-suited for applications where radial space is limited and the design envelope is constrained, making them invaluable in machinery and equipment where efficiency and reliability are paramount.

NA (needle roller bearing with machined rings): this type of bearing has a machined outer ring, which provides a precision surface for the rollers to run on. The inner ring is also typically machined to provide a precise fit with the shaft. These bearings are used in applications where high radial loads are present, such as in automotive transmissions, industrial machinery, and power tools.

RNA (needle roller bearing with machined rings): similar to NA bearings, RNA bearings have machined rings for precision performance. the "R" in RNA typically denotes bearings without an inner ring. These bearings are used in applications where the shaft is hardened and ground and acts directly as the rolling element raceway.

the main advantages of needle roller bearings with machined rings include their high load-carrying capacity, compact design, and ability to operate at high speeds. they are commonly used in various industries, including automotive, aerospace, and manufacturing, where space and weight are critical considerations.
