239/630CAK/C3W33

239/630CAK/C3W33 is a super-large-sized self-aligning roller bearing with conical inner hole and C3 large clearance. Its core function is to provide a key component for stable support and automatic alignment for medium and low-speed heavy machinery that is subjected to extreme heavy loads, has angular deviations, requires convenient installation and adjustment, and is suitable for vibration/thermal deformation conditions. It achieves angle deviation compensation through dual-row spherical rollers + spherical outer raceways. The "CA" solid brass cage enhances impact resistance and load-bearing stability. The "K" (1:12 conical inner hole) facilitates installation and adjustment through locking sleeve / disassembly sleeve. The "C3" large clearance buffers vibration and compensates for thermal expansion. The "W33" oil groove and oil hole ensure lubrication. Combined with an inner diameter of 630mm, outer diameter of 850mm, and width of 170mm, it can handle approximately 4300kN dynamic load, 8800kN static load, and a reference rotational speed of 380r/min (with a maximum rotational speed limit of 750r/min). It precisely fits complex working condition equipment such as large steel rolling machine support rollers and ultra-heavy-duty crushing machine main shafts, while meeting the requirements of support, installation adjustment, and working condition adaptation.
