    SAE J744 OCT 83 22-4 spline shaft torque spec

    Hi - could someone tell me how to find the torque spec for this shaft, it is a std SAE 13T spline shaft, 7/8 inch diameter with 1/4-20 UNC-2B internal thread. I can't seem to find this anywhere on the net. I am interested in the maximum rated torque for this shaft. Thanks;

    flushing of bearings with oil

    Thanks for the feedback, everyone, case flushing means hot oil flushing or in the case of hydraulics, running case oil through the bearing package around the shaft of the hydraulic piece of equipment, to use the case oil for lubrication and for cooling. I am not so much concerned about oil...

    flushing of bearings with oil

    I guess my question is not clear. Can we predict how much lifetime case flushing will add to bearing lifetime? I appreciate that bearing lifetime calculations are based on an L10 rating, which means that 90% of the bearings will achieve the lifetime based on the calculations. There are many...

    pulley sheave centers that will mate with metric conical 1:5 tapered k

    Thanks, ruble, is perhaps I didn't make the question clear. Our main gear motor factory is in Europe. In this case our customer asked for this shaft on a gear motor for his pulley drive system. Our customer cannot find a pulley sheave that is pre-designed (or already built) to handle a...

    pulley sheave centers that will mate with metric conical 1:5 tapered k

    Here's one for you! Our customer has bought some gear motors from us for a pulley drive system, and found out a week before receiving the gear motors that the shaft requested will not mount to his pulley sheave easily. His pulley sheave manufacturer indicated not only did he not have the...

    flushing of bearings with oil

    I know it depends on the bearing type itself, but take for example a standard overhung load adaptor with tapered roller bearings, is there a general rule of thumb as far as additive lifetime when case flushing with oil is added to improve bearing lifetime.
