The primary purpose of a shaft collar is to resist an axial load. That is to hold itself in place despite pressure along the axis of a shaft. The axial holding power is primarily a function of screw size and applied torque. However, other factors such as presence of oil, temperature, and the finish and hardness of the shaft can impact the holding power.

We are using the M1C-25 and the M1C-30 shaft collars in our design. How can we calculate the axial holding power?
Climax Metal Products
Axial load is calculated based on the screw dimension. Since both M1C-25 & M1C-30 shaft collars use the same screw, they have the same axial load capacity of about 2,000 lbs. The shaft surface finish and material can vary this calculation, so it’s important to keep that in mind as well. If you need additional information or would like to speak with one of our in-house engineers, please give us a call at 1-800-542-6552, Monday through Friday, 8:00am to 4:00pm EST.
