Ma bearing a mipira iwiri ndi oyenera ma radial load apakatikati ndi ma axial load ang'onoang'ono mbali zonse ziwiri. Kapangidwe kake ndi ntchito yake ndi kofanana ndi ma bearing a mpira umodzi. Ma bearing awa amagwiritsidwa ntchito pamene mphamvu ya katundu wa bearing ya mzere umodzi sikokwanira. Ma bearing a mipira iwiri ali ndi diameter yofanana yakunja ndi bore diameter monga ma bearing a mzere umodzi, koma ndi otakata ndipo ali ndi mphamvu yolemera kwambiri kuposa ma bearing a mpira umodzi a mndandanda wa 62 ndi 63.
