23036

23036 is a double-row self-aligning roller bearing (the basic model corresponds to the double-row self-aligning roller structure). The core positioning is to be the key supporting component for the critical parts of large heavy-duty equipment (such as the supporting rollers of large metallurgical rolling mills, the hollow shafts of mining ball mills, the main bearings of cement vertical mills, the pressing rollers of heavy paper machinery, etc.). Its cylindrical hole is suitable for tight fitting installation and has excellent self-aligning capability to compensate for the angular deviation and bending deformation of the shaft system. It can withstand extremely large radial loads and bidirectional medium axial loads and effectively resist impact and vibration. The outer ring is usually equipped with a ring-shaped lubrication groove and 3 lubrication holes (W33 structure, such as 230336/W33 model), which supports long-term online lubrication maintenance. It is made of high-quality high-carbon chromium bearing steel (GCr15) after quenching and heat treatment, taking into account high-load bearing capacity, adaptability to working conditions and operational convenience, ensuring that large heavy-duty equipment can operate stably and continuously under high-load conditions. The inner diameter is 180mm, the outer diameter is 280mm, and the width is 74mm, suitable for the heavy-duty supporting requirements of large-sized shaft systems.
