Product Description
The C3148 C31 Series CARB Toroidal Roller Bearing is engineered for heavy-duty and vibrating equipment applications. With dimensions of 240mm bore diameter, 400mm outer diameter, and 128mm width, this small-bore toroidal bearing delivers reliable, low-friction performance in demanding industrial environments. It boasts a dynamic load rating of 2320kN and static load rating of 3450kN, with the unique ability to bear bidirectional axial loads while compensating for misalignment without preload. The CARB toroidal roller bearing designation further optimizes its self-aligning capability and durability.
Ideal for use in: vibrating screens, crushers, heavy industrial gearboxes, small gearboxes, precision electric motors, light industrial fans
