The length of time for wear-in to occur varies by application. When calculating required torque always use a service factor of 1.5 to 2. It is not recommended to select a product for use at its maximum rated torque for continuous duty. PRODUCT SELECTION Torque capacity is only one factor to consider when making a product selection. Insure that you will have right product for the job by contacting our engineering department for application review and selection assistance. ®AOtlll 859-291-0849 engineering@machiii.com www.machiii.com
