idlersteelbearing

They are used in heavy duty applications where loads and speeds are greater than required for unground bearings-usually over 2000 RPM. Many are used on modern combines. Aetna straight belt idlers for flat belts are available with double row bearings and bushed to clear 1/2″, 5/8″ and 3/4″ bolts. Aetna belt idlers are generally used as tensioners or direction changers. Permanently lubricated and sealed against grime and dirt. Fit into existing design with little or no engineering changes or are readily adapted to new designs. Advantages Heavy gauge precision formed steel with annular strengthening rib. Double row of steel rivets Double row lubricated for life sealed precision angular contact bearing for higher capacity and rigidity Steel bushing to provide proper bolt clamping and centering Basic radial load rating of precision bearing is 3,340 pounds
