Product Description
The C3996M C39 Series CARB Toroidal Roller Bearing is engineered for large bore and low-friction applications. With dimensions of 480mm bore diameter, 650mm outer diameter, and 128mm width, this medium-bore toroidal bearing delivers reliable, low-friction performance in demanding industrial environments. It boasts a dynamic load rating of 3100kN and static load rating of 6100kN, with the unique ability to bear bidirectional axial loads while compensating for misalignment without preload. This bearing is equipped with machined brass solid cage for enhanced operational stability and service life. The CARB toroidal roller bearing designation further optimizes its self-aligning capability and durability.
Ideal for use in: wind turbine gearboxes, large industrial pumps, paper mill machinery, industrial gearboxes, material handling systems, medium-sized mining equipment
