• Spherical outer raceway realizes superior self-aligning capacity, tolerates shaft deflection & housing misalignment
• Double symmetrical roller layout bears ultra-heavy radial and two-way axial thrust simultaneously
• Thick solid brass cage maintains stable structure under low-speed heavy load & high temperature
• Optimized convex roller profile reduces edge stress, lowers friction and heat generation
• Large load rating design extends service life under continuous heavy-duty mining/cement working conditions
• Custom W33 lubrication groove, clearance grades (C0/C3/C4) and precision classes supported
• 👉 Greatly reduce unplanned downtime for heavy industrial rotary equipment

This heavy-duty spherical roller bearing is widely used in: Mining ball mill, vertical mill and crusher main shaft assemblies Cement rotary kiln, roller press and large material conveying equipment Metallurgy rolling mill, heavy gearbox and industrial large speed reducers Paper machinery, ship propulsion shaft and heavy construction rotary machinery General heavy-load equipment requiring strong self-aligning and high load capacity
