MCGILL MCYR-20 Bearing points for attention :

(1) Standard bearing has a crowned roller outside diameter. For straight cylindrical outside diameter, add suffix "X". (Example – MCYRR-15-X or MCYR-15-SX)

(2) Tolerance limits for Roller Diameter are shown below.

(3) For a tight fit and heavy loads, use ISO tolerance j6.

(4) 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 relubrications is required. Actual bearing testing in the specific application should be conducted if the anticipated operating speed approaches the listed limiting speed."

(5) Dynamic load should not exceed 50% of Dynamic Rating as a track roller.
