Description

SKF – 6202-2Z – Deep Groove Ball Bearing

The SKF 6202-2Z is a premium-quality deep groove ball bearing designed to deliver smooth, reliable performance across a wide range of applications. Manufactured by SKF, a global leader in bearing technology, this bearing belongs to the popular 6200 series and is widely used in industrial, automotive, agricultural, and household machinery. Known for its compact dimensions, durable construction, and excellent high-speed performance, the SKF 6202-2Z is a go-to solution for engineers and technicians seeking efficiency, durability, and low maintenance.

This specific model features metal shields on both sides — indicated by the “2Z” suffix — which serve to protect the internal rolling elements and grease from contaminants like dust, dirt, and moisture. The shields also help retain the lubricant inside the bearing, enhancing its operational life and reducing the need for re-lubrication. These non-contact metal shields make the 6202-2Z ideal for use in relatively clean environments or enclosed systems where protection and high-speed operation are both critical.

Construction and Design

The deep groove raceway geometry of this bearing allows it to carry both radial loads and limited axial loads in both directions. Its design minimizes friction, allowing it to operate efficiently at high speeds while maintaining quiet and smooth motion. This makes it ideal for applications such as electric motors, power tools, fans, pumps, gearboxes, and bicycles.

The inner and outer rings, as well as the steel balls, are manufactured from high-grade, heat-treated chromium steel, which provides excellent wear resistance, hardness, and dimensional stability. This ensures consistent performance under varying operating conditions, including moderate loads and rotational speeds.

The metal shields are tightly secured in the outer ring’s grooves, creating a protective barrier that prevents debris from entering the bearing while still allowing for low-friction rotation. These shields are not designed to be airtight but are highly effective at blocking common contaminants that could cause premature bearing wear.

Performance Benefits

The SKF 6202-2Z is optimized for high-speed operation, offering:

• Low frictional torque, which reduces energy consumption

• Extended service life, due to sealed grease and contamination protection

• Quiet operation, ideal for sensitive environments such as HVAC systems and household appliances

• Compact size, enabling use in tight mechanical assemblies

It is pre-lubricated with high-performance SKF grease, suitable for life-lubricated applications. This means there’s no need for re-lubrication under normal operating conditions, which significantly reduces maintenance efforts and costs.

Typical Applications

Thanks to its versatility, compact size, and efficiency, the SKF 6202-2Z is widely used in:

• Electric motors and generators

• Small pumps and compressors

• Fans and blowers

• Agricultural machinery

• Home appliances (washing machines, dryers)

• Power tools and garden equipment

• Bicycle hubs and rollers

Its ability to handle both radial and axial loads while maintaining smooth and stable operation under varying speeds makes it suitable for dynamic environments.
