Product Description
The C31/670MB C31 Series CARB Toroidal Roller Bearing is engineered for heavy-duty and vibrating equipment applications. With dimensions of 670mm bore diameter, 1090mm outer diameter, and 336mm width, this large-bore toroidal bearing delivers reliable, low-friction performance in demanding industrial environments. It boasts a dynamic load rating of 12000kN and static load rating of 22000kN, 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: vibrating screens, crushers, heavy industrial gearboxes, heavy mining equipment, construction machinery, large rolling mills
