The NSK 6206ZZ Deep Groove Ball Bearing is a premium single-row bearing built for smooth, reliable operation under combined radial and moderate axial loads. Manufactured by NSK Japan, this sealed (double-shielded) bearing delivers low friction, high-speed capability, and long service life. It’s widely used in automotive components and industrial machinery.

Technical Specifications

The “ZZ” suffix means this bearing has metal shields on both sides, offering protection from dust and particles while maintaining low friction and high-speed rotation.

Product Overview

Deep groove ball bearings are one of the most versatile and widely used bearing types due to their simplicity, strength, and ability to support loads in multiple directions. The 6206 series is especially common in compact rotating components.

This 6206ZZ model is designed for:

• Radial loads in both directions

• Moderate axial loads

• High-speed and continuous operation

• Low-noise and low-vibration environments

Its double shields help keep internal grease in and contaminants out, making it suitable for applications exposed to light dust and debris.

Applications & Vehicle Use

Bearings like 6206ZZ are dimension-based — they’re not tied to a specific vehicle model/year because automotive components may use different bearing types depending on engine/accessory OEM design. However, when a vehicle’s OEM parts list calls for a bearing with the code 6206ZZ or matching dimensions (30×62×16 mm), this NSK bearing is a correct replacement.

🔩 Typical Automotive & Machine Applications

This bearing is commonly used in:

• Alternator shafts

• Water pump pulleys

• Tensioner / idler pulleys

• Transmission shafts

• Starter motors

• Power steering pump shafts
  (Check your OEM parts manual or old bearing code to confirm)

🛠 Industrial Usage

Also widely used in:

• Electric motors

• Conveyor systems

• Pumps and compressors

• Fans and blowers

• Gearboxes

• Machine tools
  (Deep groove bearings are the most common bearing type across industries)

Related Brand Equivalent Part Numbers

When searching for compatible or interchangeable bearings with the same 30×62×16 mm size and shielded design, you may also encounter:

• SKF: 6206-2Z or 6206ZZ

• NTN: 6206ZZ

• FAG: 6206-2RSR (sealed version)

• KOYO: 6206-2RS/ZZ

• TIMKEN: 6206ZZ

⚠ These equivalents are dimension-based matches — always confirm that sealing type (ZZ vs 2RS), load ratings, and materials meet your application requirements before substitution.

How to Confirm Fitment for Your Vehicle

To ensure the NSK 6206ZZ is the correct replacement bearing:

1. Check the old bearing — look for “6206ZZ” stamped on the side or in your vehicle’s parts manual.

2. Match the dimensions:

   • Bore: 30 mm

   • Outer Diameter: 62 mm

   • Width: 16 mm

3. Confirm sealing style: “ZZ” = metal shields on both sides.

4. Use your vehicle year/make/model plus “bearing 30×62×16” in OEM parts searches to ensure correct application.
