01. High Combined Load Handling

Featuring optimized contact angles (15° C, 25° AC, or 40° B), the 7201 Series is designed to sustain substantial simultaneous radial and axial forces, offering greater load capacity and improved system rigidity for demanding mechanical applications.

02. Reliable and Long-Lasting Operation

Manufactured from premium chrome steel and available in elevated P5 precision grades, these bearings ensure reduced vibration, consistent running accuracy, and extended service intervals even under continuous operation in tough industrial environments.

03. Adaptable to Diverse Operating Conditions

Supports single or preloaded paired mounting to achieve desired stiffness and load distribution. Available in open, shielded (ZZ), or sealed (2RS) versions, providing solutions for environments ranging from clean, well-lubricated systems to those with potential contaminant exposure.

Design & Configuration

The 7201 bearing is typically offered in an open design to facilitate custom lubrication strategies. The addition of non-contact steel shields (ZZ) provides effective protection against coarse contaminants. For applications requiring a sealed, maintenance-free solution, the 2RS variant with rubber seals is ideal. Engineers can select the contact angle to match application priorities: 15° (C) for higher speeds, 25° (AC) for a balanced performance, or 40° (B) for maximum axial stiffness under heavy loads.

“In heavy-duty industrial gearboxes and compressor systems, the 7201 AC bearing is valued for its ability to handle significant combined loads while maintaining precise shaft alignment over long service periods.”
