6322 ZZ Deep Groove Ball Bearing 110x240x50 mm | 6300 Series | Double Shielded Design
A robust industrial bearing utilizing the proven deep groove geometry to deliver high radial load capacity and smooth rotational performance. Engineered for consistent operation at speeds reaching 3,900 r/min with grease lubrication. The 6322 ZZ is manufactured from high-quality chrome steel to withstand continuous operation in demanding environments, making it a trusted component for heavy machinery and power transmission systems.

This large-frame bearing is ideally suited for a broad spectrum of heavy industrial equipment:
As a large-format 63-series bearing, the 6322 ZZ delivers outstanding radial load capacity with a dynamic load rating of 205 kN. Manufactured from high-purity chrome steel (GCr15/SAE 52100), its robust construction ensures excellent durability and resistance to wear under continuous heavy loads, guaranteeing extended service life in the most demanding conditions.
This variant comes standard with double metal shields (ZZ) , providing effective protection against the ingress of dust, debris, and contaminants while retaining lubricating grease for maintenance-free operation. The shielding design minimizes friction while extending bearing life in dirty environments.
Manufactured to standard industrial precision tolerances (P0), the 6322 ZZ ensures consistent quality and reliable performance. The precision-ground deep raceway grooves and high-grade steel balls facilitate stable, vibration-free rotation, contributing to efficient power transmission and reduced noise levels in heavy machinery.

While the 6322 ZZ is supplied as standard with double shields, the base open design allows for customization to meet specific operational requirements:
• Double Shield (6322-ZZ / 2Z): Standard configuration. Provides excellent protection and grease retention for general industrial use.
• Double Seal (6322-2RS / 2RS1): For enhanced protection against moisture and fine contaminants in harsh environments.
• Open Bearing (6322): For high-speed applications requiring oil lubrication.
• Increased Clearance (6322 ZZ C3): Recommended for applications where interference fits or temperature differentials may reduce internal clearances.
"For heavy electric motors, large industrial gearboxes, and mining equipment, the 6322 ZZ delivers reliable, high-capacity bearing performance. Specify seal suffixes or C3 clearance to match your specific operating environment."
