Duplex Ball Bearings
Duplex Bearings, otherwise known as 'Four Point Angular Contact' Ball Bearings belong the angular contact ball bearing family. Duplex bearings are different from 7 series single row bearings in that they can accept thrust loads along both axis, as well limited radial loads. Duplex bearings have a contact angle of 35° and a split inner race to allow for the maximum number of rolling elements. Having a split inner race these bearings are separable which facilitates mounting as the outer race (along with cage and ball set) and the inner rings can all be mounted separately.
