01. Precision-Ground for Smooth, Reliable Operation

Manufactured from high-quality chrome steel with precision-ground raceways, the 6224-2Z delivers consistently smooth running characteristics with minimal vibration. The bearing features a stamped steel cage for reliable ball guidance and is available with Normal (C0) internal clearance, suitable for most standard operating conditions.

02. Exceptional Load Carrying Capacity

The 6224-2Z, with its 120×215×40 mm dimensions, delivers substantial radial load capacity with dynamic load rating of 155 kN and static load rating of 131 kN . This robust construction ensures reliable performance in heavy industrial applications where consistent operation under significant loads is required.

03. Effective Contamination Protection

The double metal shield (2Z) configuration provides reliable exclusion of larger contaminants and debris while minimizing frictional torque. This design supports higher rotational speeds compared to contact seals, with grease lubrication permitting speeds up to 2,800-3,400 r/min depending on operating conditions.

04. Wide Operating Temperature Range

Engineered to perform across diverse industrial environments, the 6224-2Z operates reliably within a temperature range of -50°C to +150°C, accommodating thermal expansion and contraction in varying application conditions.

Design & Configuration

The standard configuration for the 6224-2Z includes double metal shields and factory-applied lithium-based grease. This design offers dependable protection for applications in relatively clean industrial environments where moderate to high speeds are required . For applications requiring enhanced sealing against moisture or fine particulate, the rubber-sealed version (6224-2RS) is available.

Mounting considerations: Minimum abutment shoulder diameter (da) is 132 mm, maximum housing shoulder diameter (Da) is 203 mm, with maximum fillet radius of 2.1 mm.

"Ideal for large electric motors, industrial pumps, and heavy machinery, the 6224-2Z ensures dependable long-term operation under substantial radial loads. Its effective shield protection against larger contaminants combined with high-speed capability makes it a preferred choice for maintenance professionals and OEMs seeking reliable performance in demanding industrial applications."
