Self-aligning Roller Bearing

23856CAMA bearing is a double-row self-aligning roller bearing. The suffix "CAMA" indicates that it uses an outer ring-guided machined brass cage and has guard edges on both sides of the inner ring, along with an inner ring-guided guide ring. Its standard size is an inner diameter of 280mm, an outer diameter of 355mm, and a thickness of 52mm. There may be slight size differences among different manufacturers. This bearing has obvious core advantages. It can simultaneously withstand large radial loads and bidirectional axial loads, suitable for heavy-duty scenarios. It also has excellent self-aligning performance, which can compensate for the angle deviation between the shaft and the bearing housing or shaft bending problems, reducing the impact of installation and usage errors. At the same time, it is structurally strong, with outstanding shock resistance and vibration resistance capabilities, and can adapt to harsh working environments. In terms of material selection, it uses high-carbon chromium bearing steel (such as GCr15). This material ensures that the bearing has high hardness, wear resistance, and fatigue strength, thereby extending its service life. Based on these performance characteristics, it is widely used in equipment such as steel rolling machines and continuous casting equipment in the metallurgical industry, crushers, ball mills, rotary kilns and grinding machines in mining machinery, rotary kilns and grinding machines in cement machinery, main shafts of wind turbines in wind power generation, drying and calendering sections and press sections of paper machinery.
