Questions about this item
What comes in the box and do I need to buy hubs separately?
The package contains only the red polyurethane spider rated at 165 in-lb. Matching JC26 or MJC41 hubs are sold separately.
How do I choose between the JC26 and MJC41 size codes listed for this spider?
Both size codes share the same 1 5/8 in outside diameter and 165 in-lb torque rating, so the spider fits either hub series without modification.
What does the 165 in-lb torque rating mean when the coupling runs at 100 RPM in a real machine?
At 100 RPM the insert transmits 0.5236 hp while staying within its 165 in-lb torque limit and 8,000 RPM maximum speed.
