Heavy Duty Spherical Roller Bearing 280 mm Bore 420 mm OD 106 mm Wide With Straight Bore Fit Lubrication Groove Three Hole Outer Ring Brass Cage C4 Clearance For Radial Loads And Precision

Single heavy-duty spherical roller bearing with straight bore
✔️ 280 mm bore, 420 mm OD, 106 mm wide, brass cage, three lubrication holes

This heavy-duty spherical roller bearing is designed to handle high radial loads with precise alignment. It’s commonly used in industrial machinery, power transmission setups, conveyors, and rolling equipment where robust support and smooth rotation are needed.

✅ Axially symmetric races to support radial loads while maintaining high speeds and rotational accuracy
✅ Straight bore fits conventional cylindrical shafts
✅ C4 radial internal clearance for radial slack between the inner and outer rings is greater than CN (normal) and C3 to compensate for thermal expansion
✅ Brass cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise
✅ Three lubrication holes in the outer ring for lubrication in place

💡 What is a heavy duty spherical roller bearing used for in industrial machinery? This handy long-tail question helps buyers understand core uses. - High radial load capacity on rotating equipment - Maintains alignment under heavy loads and thermal expansion - Straight bore simplifies shaft mounting - Brass cage reduces friction, noise, wear
