23084Q4

23084Q4 is a double-row self-aligning roller bearing designed for heavy-duty low-speed operating conditions (Q4 usually refers to large clearance + optimized internal design, suitable for thermal expansion / shock scenarios). The core function is to provide radial + bidirectional axial high load capacity and automatic self-aligning capability for the main shaft systems of heavy equipment such as metallurgical rolling mills, mining crushers, and building material ball mills. It can accommodate shaft system angle deviations and vibration shocks. The large clearance design is suitable for thermal expansion and installation errors of the working conditions. The double-row roller structure ensures stable support under heavy loads. It is a highly reliable support solution for critical shaft systems of heavy machinery, suitable for harsh working conditions that require resistance to shock, thermal deformation, and frequent start-stop operations, helping the equipment operate stably and reliably for a long time.
