SKF 6201-2Z – Single Row Deep Groove Ball Bearing (Double Shielded)

The SKF 6201-2Z is a compact and reliable single row deep groove ball bearing designed for efficient operation at high speeds with minimal friction and maintenance. Manufactured by SKF, a globally recognized leader in bearing technology, the 6201-2Z is part of the widely used 6200 series — known for its precision, durability, and versatile performance.

This bearing features metal shields on both sides (2Z), offering effective protection from contaminants like dust and debris, while retaining the lubricant for longer service life. Its compact size and high-speed capability make it suitable for small machines, electric motors, and appliances that require quiet, stable, and long-lasting performance.

Design & Functional Features:

1. Deep Groove Geometry

The SKF 6201-2Z is designed with deep raceway grooves and close conformity between the raceways and balls. This allows it to handle radial loads and light axial loads in both directions, making it one of the most versatile and widely used bearing types in rotating machinery.

2. Double Metal Shields (2Z)

The “2Z” designation refers to metal shields on both sides of the bearing, which offer the following benefits:

• Protection against contamination from dust, dirt, and debris

• Retention of factory-applied grease for long-term lubrication

• Reduced maintenance requirements

• Support for high-speed operation due to non-contact design

The shields do not touch the inner ring, minimizing friction and enabling the bearing to run cooler and more efficiently than sealed variants.

3. High-Speed Performance

With a limiting speed of up to 26,000 RPM, the 6201-2Z performs reliably in high-speed applications. Its low noise and low vibration operation make it ideal for electric motors, pumps, fans, and other rotating equipment where performance and smoothness matter.

4. High-Quality Materials

SKF manufactures the 6201-2Z using high-grade chrome steel, known for:

• Excellent fatigue resistance

• High wear durability

• Dimensional stability under thermal and mechanical loads

• Superior surface finish for low-noise operation

Common Applications:

The compact size and efficiency of the SKF 6201-2Z make it suitable for a wide variety of industries and machinery, including:

• Electric motors and alternators

• Small pumps and compressors

• Fans and HVAC units

• Power tools and garden equipment

• Automotive parts and transmissions

• Home appliances (washing machines, dryers, vacuum cleaners)

• Industrial automation systems

Its high-speed capability and low maintenance make it especially useful in compact, continuously operating machinery.

Key Benefits:

• Compact, lightweight design for space-limited systems

• Maintenance-free under normal operating conditions

• Dual shields provide extended bearing life and lubricant retention

• Low-friction operation enables high-speed efficiency

• Quiet and vibration-free performance for sensitive applications

• Standardized dimensions for easy interchangeability and replacement

• Excellent value for long-term use in both OEM and maintenance scenarios

---

Operating Conditions:

• Temperature Range: -30°C to +120°C

• Lubrication: Pre-lubricated with high-performance grease

• Alignment Tolerance: Low — requires precise mounting alignment

• Mounting Notes: Use proper tools to prevent damage during installation; do not remove shields

---

Packaging & Handling:

SKF 6201-2Z bearings are individually packed in sealed cartons to prevent contamination. Always store them in a dry, clean place, and avoid contact with dust, moisture, or chemicals during handling. Use gloves or clean tools when mounting to avoid introducing debris into the bearing system.

---

Summary:
