MCGILL MCFR-90 BEARINGS , METRIC CAMAROL® Bearings

MCGILL MCFR-90 Bearing points for attention :

(1) Standard bearing has a crowned roller outside diameter. For straight cylindrical outside roller diameter, add suffix "X". Example – MCFR-35-X or MCF-35-SX
(2) Tolerance limits for Roller Diameter are shown below.
(3) Stud Diameter "SD" per ISO tolerance h7, shown below.
(4) Clamping torque is based on dry threads. If threads are lubricated, use half of value shown."
(5) Static load rating is based on stud strength or on internal rolling element load distribution stresses."
(6) Dynamic load should not exceed 50% of Dynamic Rating as a track roller.
(7) 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. More frequent relubrication is required when operating at higher speeds. Actual bearing testing in the specific application should be conducted if the anticipated operating speed approaches the listed limiting speed."

• Sizes marked have no lube holes in threaded end of stud.
