Product Description

The C 4168 K30MB/C3 Bearing is a high-precision Cylindrical Roller industrial bearing designed for heavy-load applications requiring robust radial support and thermal stability. Featuring C3 clearance classification, it accommodates thermal expansion in demanding environments with operating temperatures ranging from -20°C to +150°C. This bearing supports radial loads up to 520 kN and operates at speeds up to 2,800 RPM under optimal lubrication. Its K30MB/C3 designation indicates a reinforced brass cage structure for enhanced durability in high-vibration scenarios. Widely used in steel mills, mining equipment, and heavy machinery, its key advantages include extended service life, reduced friction, and compatibility with ISO dimensional standards. A potential drawback is reduced efficiency in ultra-high-speed applications due to increased C3 internal clearance. The sealed design minimizes contamination, making it ideal for dusty or humid industrial settings.
