Description:
Taperednbsp;rollernbsp;bearingsnbsp;havenbsp;taperednbsp;innernbsp;andnbsp;outernbsp;ringnbsp;racewaysnbsp;betweennbsp;whichnbsp;taperednbsp;
rollersnbsp;arenbsp;arranged.nbsp;Thenbsp;projectionnbsp;linesnbsp;ofnbsp;allnbsp;thenbsp;taperednbsp;surfacesnbsp;meetnbsp;atnbsp;anbsp;commonnbsp;

fornbsp;thenbsp;accommodationnbsp;ofnbsp;combinednbsp;(radialnbsp;andnbsp;axial)nbsp;loads.nbsp;Thenbsp;axialnbsp;loadnbsp;carryingnbsp;capacitynbsp;

Taperednbsp;rollernbsp;bearingsnbsp;arenbsp;generallynbsp;separable,nbsp;i.e.nbsp;thenbsp;cone,nbsp;consistingnbsp;ofnbsp;thenbsp;innernbsp;ring
withnbsp;rollernbsp;andnbsp;cagenbsp;assembly,nbsp;cannbsp;benbsp;mountednbsp;separatelynbsp;fromnbsp;thenbsp;cupnbsp;(outernbsp;ring).
