MCGILL MCFD-52 Bearing points for attention :

(1) Standard bearing has a crowned roller outside diameter. For straight cylindrical outside diameter, add suffix "X". (Example – MCFD-35-X)

(2) Since load, lubrication method, temperature and other factors affect the maximum operating speed, it is impossible to determine precise limiting speed. The
listed limiting speeds are based on lightly loaded bearings having adequate lubrication and are listed only as a design guide. If grease lubricated, frequent
relubrication is required. Actual bearing testing in the specific application should be conducted if the anticipated operating speed approaches the listed limiting
speed."

(3) Clamping torque is based on dry threads. If threads are lubricated, use half of value shown.
