SPHERICAL ROLLER BEARINGS
SPHERICAL ROLLER BEARINGS – continued • Shaft and housing fits, internal clearances, tolerances and other technical data for these bearings are found in the engineering section of this catalog and the Timken Engineering Manual (order no. 10424). Bearings are available with a tapered bore for adapter-type mounting. To order, add the suffix “K” to bearing number (e.g., 23120K). Consult your Timken engineer and www.timken.com for up-to-date information about the availability of the bearings you have selected.
