6210-2Z Deep Groove Ball Bearing For Industrial Power Transmission | 50×90×20 mm

The 6210-2Z is a versatile, single-row deep groove ball bearing engineered for a wide spectrum of industrial machinery requiring reliable performance under moderate to high loads. Featuring dual Z-type metal shields, this bearing provides effective protection against the ingress of dust and solid contaminants while maintaining low frictional torque. With a 50 mm bore and a robust 20 mm width, it is the preferred choice for electric motors, pumps, and gearboxes where durability and contamination resistance are critical for extended service life.



6210-2Z Deep Groove Ball Bearing 50x90x20 mm | ISO 62 Series – Light | Double Shielded

This precision bearing utilizes a classic deep groove raceway design, enabling stable high-speed performance up to 15,000 r/min (Grease). The 6210-2Z is engineered to accommodate substantial radial loads as well as axial loads in both directions, making it exceptionally suited for heavy-duty applications in industrial machinery, automotive components, and agricultural equipment where consistent, low-friction operation is required.

Key Performance Features

01. Robust Design with High Load Capacity

Conforming to the popular 62-series light section, the 50×90×20 mm configuration delivers a high dynamic load rating of 37.1 kN. This robust construction ensures reliable performance in applications where substantial radial and axial forces are present.

02. Effective Contaminant Exclusion

Double Z-type non-contact steel shields provide a reliable barrier against dust, dirt, and other airborne particulates from both sides. This design helps retain lubricant integrity and significantly extends the operational life of the bearing in harsh environments without introducing significant drag.

03. Optimized for High-Speed and Low Noise

Precision-manufactured components and a rigid pressed steel cage ensure consistent, quiet operation with minimal vibration. This makes the 6210-2Z suitable for high-speed applications, supporting stable performance in sensitive devices like electric motors and precision spindles.
