ZVL 6203 ZZ Deep Groove Ball Bearing 17x40x12 mm

Premium Shielded Deep Groove Ball Bearing for Industrial and OEM Applications

The ZVL 6203 ZZ 17x40x12 mm is a premium single-row deep groove ball bearing designed for reliable operation at high rotational speeds while supporting radial loads and moderate axial loads in both directions. Equipped with double metal shields (ZZ) and factory-filled with high-quality grease, it provides long-lasting, maintenance-free performance under normal operating conditions while protecting the bearing against dust and solid contaminants.

Manufactured from premium-grade bearing steel, the ZVL 6203 ZZ delivers excellent running accuracy, low friction, quiet operation and extended service life, making it an ideal solution for demanding industrial, agricultural and OEM applications.

Applications

The ZVL 6203 ZZ is widely used in:

• Electric motors
• Industrial pumps
• Gearboxes
• Conveyor systems
• Agricultural machinery
• Industrial fans
• Compressors
• Power tools
• Industrial automation equipment
• Power transmission systems

Its shielded design makes it ideal for clean and moderately dusty environments where low friction and high rotational speed are essential.

Construction and Design

Key design features include:

• Single-row deep groove ball bearing
• Double metal shields (ZZ)
• Factory pre-lubricated
• Maintenance-free operation
• High-speed capability
• Low-friction design
• Steel cage
• Precision-ground raceways

The ZZ metal shields help retain lubricant while protecting the rolling elements from dust and solid particles without making contact with the inner ring, allowing higher operating speeds than rubber-sealed bearings.

Material Properties

Manufactured from premium bearing steel, the bearing provides:

• High wear resistance
• Excellent fatigue strength
• High radial load capacity
• Moderate axial load capacity in both directions
• Excellent dimensional stability
• Smooth and quiet operation
• Long operational service life
• Reliable performance under continuous operation

FAQ

What does ZZ mean?

ZZ indicates that the bearing is equipped with metal shields on both sides. They retain the lubricant while protecting the bearing from dust and solid contaminants and allow higher operating speeds than contact rubber seals.

What are the dimensions of the ZVL 6203 ZZ bearing?

The bearing has an inner diameter of 17 mm, an outer diameter of 40 mm, and a width of 12 mm.

Is the bearing pre-lubricated?

Yes. The bearing is factory-filled with high-quality grease and is ready for installation without additional lubrication under normal operating conditions.

Where is the ZVL 6203 ZZ commonly used?

It is widely used in electric motors, pumps, gearboxes, compressors, conveyor systems, fans and many industrial machines.

What are the advantages of a ZZ shielded bearing?

ZZ shielded bearings provide excellent high-speed performance, low friction, long service life and protection against dust while maintaining lower running resistance than contact-sealed bearings.
