What is your Axial Load Capability?

Collar resistance to axial motion on the shaft is primarily a function of screw size. The tables indicate maximum static load that a collar will support without slippage. It is based on screws atfull recommended seating torque, and for set screw collars, shaft hardness not exceeding Rockwell C35.

Load capability is reduced with stainless steel screws because of lower seating torque. Load capability may be nearly doubled with set screw collars by adding a second set screw. Threaded collars and shafts have much greater axial load capability.

The tables also indicate “typical” maximum values and are not a guarantee under all conditions. Values are only a guide and must be evaluated by customers based on individual application. Climax does not intend these values to serve as a warranty.

NOTE: The Axial Load data presented is based on the median bore size for a particular screw size.

T=Torque required to rotate shaft in coupling (in-lb), F=Axial load based on a given screw size (lb), R=Bore radius (in) [T= (F x 2) x R]

Disclaimer: The axial load and torque data presented are based on limited test results and are not a guarantee of minimum or maximum values under all conditions.
