21320CC/W33 Spherical Roller Bearing – WZA Bearing | Precision P6/P5 | Heavy-Duty Industrial Use
The WZA 21320CC/W33 spherical roller bearing is designed for high-performance and heavy-load applications across demanding industrial environments. With a double-row spherical design and a CC-type steel cage, it provides outstanding load capacity, self-aligning capability, and long service life under dynamic conditions.
Manufactured to P6 / P5 precision standards, this bearing ensures low friction, high-speed performance, and minimal maintenance. The W33 lubrication groove and holes further enhance heat dissipation and grease distribution, making it an ideal choice for machinery operating in high-temperature or high-impact environments.
