NA/NKI/NA/NK type needle bearing with ribs
Description of Products
NA/NKI/NA/NK type needle bearing with ribs are composed of one or two ferrules and a needle roller set with a cage. It has a smaller volume and a higher load-carrying capacity. Therefore, this kind of bearing can meet the requirements of light weight, small space occupation and high transmission power. Depending on the application, bearings with or without inner ring can be used.
Outer ring double rib (or double lock ring) needle roller bearing with cage NA, NKI type . The inner ring and outer ring (with lock ring, full set of needle rollers and cage) can be installed separately, with high authority speed, divided into single row and double row.
NA and NKI type bearings without inner ring are RNA and NK type needle roller bearings. This type of bearing has no inner ring and is suitable for supporting structures with limited radial installation dimensions.
