331656

The 331656 is a high-performance double-row tapered roller bearing specifically built to handle the brutal radial and axial stresses found in large-scale industrial drives. With a 415.925 mm bore and 590.55 mm OD, this TDO-configured unit utilizes a steep contact angle to stabilize shafts against significant tilting moments. Unlike standard single-row setups, the 331656 comes with a factory-calibrated intermediate spacer, meaning the axial internal clearance (BEP) is preset. This eliminates the guesswork during field installation, ensuring the 244.475 mm wide assembly maintains rigid system integration even under fluctuating thermal conditions.

In terms of sheer capacity, the 331656 is a beast, offering a dynamic load rating (C) of 4175 kN and a static threshold (C_0) of 9650 kN. We've focused on the internal raceway geometry to minimize "edge loading"-a common killer of bearings in mining and steel mill applications. The use of a high-strength pressed steel cage ensures the rollers stay aligned at high speeds, while the back-to-back arrangement provides the necessary footprint for heavy-duty gearboxes and rolling mills. If you are looking to cut down on unscheduled downtime and need a bearing that handles a fatigue load limit of 720 kN without breaking a sweat, this 331656 variant is the industry standard.
