23052K/C3W33

23052K/C3W33 is a double-row self-aligning roller bearing with an inner diameter of 260mm, an outer diameter of 400mm, and a width of 104mm. The inner ring features a 1:12 taper hole that allows for precise fine-tuning of the radial clearance. It is designed to accommodate C3 large clearance to adapt to the thermal expansion and contraction of the shaft system under high-temperature conditions. The outer ring is equipped with a W33 annular lubrication groove and an oil injection hole, which support online lubrication without stopping the machine. The core function is to provide a high-stiffness, self-aligning, high-temperature expansion and contraction-resistant, and convenient online lubrication integrated stable support for the shaft systems of heavy-duty and highly impact-resistant equipment such as metallurgical hot rolling machines, mining ball mills, cement vertical mills, large-scale port lifting equipment, and high-temperature equipment reducers. This support component compensates for ≤2° coaxiality errors, can withstand extremely large radial loads and bidirectional axial loads, and is suitable for low to medium-speed, high-temperature, harsh environments with strict requirements for gap adaptability, maintenance convenience, and operational stability. It is the core preferred supporting component for high-load, impact-resistant, adjustable gap, long-term maintenance-free shaft systems of high-temperature heavy-duty equipment.
