The 6207 deep groove ball bearing with seals or shields represents a pinnacle of reliability and efficiency in rotary motion solutions. Designed to excel in diverse operating conditions, this bearing combines robust construction with advanced sealing technologies to deliver exceptional performance across industrial, automotive, and automation sectors.
Radial & Axial Load Capacity:
Engineered with a deep raceway geometry (bore: 35 mm, OD: 72 mm, width: 17 mm), the 6207 bearing to 14.0 kN and axial loads up to 8.3 kN in both directions. This dual-load capability eliminates the need for complex bearing arrangements in many applications.
High-Speed Performance:
Precision-ground steel components and controlled internal clearance enable stable operation at speeds exceeding 10,000 RPM (grease-lubricated). The optimized contact angle reduces centrifugal forces at ultra-high speeds.
Shield vs. Seal Configurations:
ZZ Shield (Non-Contact): Maintains 85-90% of open-bearing speed capability while providing particle exclusion
2RS Seal (Contact): Triple-lip nit rubber seals offer IP65-equivalent protection with <5% friction increase vs. open bearings
Contamination Resistance:
Lab-tested to withstand particulate contamination levels up to ISO 4406 18/16/13 when properly shielded, doubling service life in dirty environments.
**
Pre-greased with high-performance polyurea complex grease (standard), providing 3,000+ hours of continuous operation at 70°C. Optional PTFE-thickened greases extend relubrication intervals by 40%.
Corrosion Protection:
Passivated surfaces with optional Zn-Ni coating achieve 500+ hours in salt spray testing (ASTM B117), critical for marine and food processing applications.
