RNA22 series Supporting track roller bearing
RNA22 ... 2RS, NA22 ... 2RS type support roller
RNA22..2RS for the outer double-wall, a cage, curved roller roller bearings. The diameter of this roller is the same as that of the STO series rollers. But they are slightly wider, double-sided sealing structure so that it does not require maintenance, the use of temperature range of -20 ℃ -120 ℃. When installing the RNA22 ... 2RS series bearing rollers without the inner ring, care should be taken not to damage the seals. The outer ring requires end-face guidance. NA22..2RS for the outer double-wall, a cage, curved roller roller bearings.
According to customer demand processing into cylindrical roller, with the suffix: "X" said, for example: RNA22 / 6.2RS, NA22 / 6.2RS.
