SKF 6209-2Z – Single Row Deep Groove Ball Bearing

The SKF 6209-2Z is a high-quality, single row deep groove ball bearing designed for demanding industrial and automotive applications. Manufactured by SKF, a global leader in bearing technology and engineering solutions, this bearing offers excellent performance, durability, and efficiency. With a robust build and precision-engineered components, the SKF 6209-2Z is ideal for applications requiring reliable rotational performance and minimal maintenance.

Key Features:

1. Shielded Design (2Z)
   The “2Z” suffix denotes that the bearing is fitted with metal shields on both sides. These shields help protect the internal components from dust, dirt, and other contaminants while retaining the lubricant inside. This design significantly reduces the need for frequent lubrication and extends the bearing’s service life in moderately contaminated environments.

2. Standard Dimensions

   • Bore diameter (ID): 45 mm

   • Outside diameter (OD): 85 mm

   • Width (B): 19 mm
     These ISO-standard dimensions make the 6209-2Z easily interchangeable and compatible with a wide variety of equipment.

3. Load Carrying Capacity
   The SKF 6209-2Z is capable of handling both radial and limited axial loads in both directions.

   • Dynamic load rating (C): 27.9 kN

   • Static load rating (C0): 15.3 kN

   • Fatigue load limit (Pu): 0.65 kN
     This load capacity ensures dependable operation under varied load conditions, making it suitable for medium to high-speed machinery.

4. High-Speed Capability
   This bearing is designed for high-speed operation with low friction. The optimized internal geometry, high-quality steel construction, and effective sealing system ensure smooth rotation and minimal noise, even at high RPMs. The limiting speed for the SKF 6209-2Z is approximately 9,000 rpm (depending on operating conditions).

5. Weight and Material

   • Weight: Approx. 0.428 kg

   • Material: High-grade chromium steel
     The bearing is manufactured using SKF’s superior-grade steel, known for its hardness, wear resistance, and fatigue life. The outer and inner rings, along with the rolling elements, are precisely machined for high dimensional accuracy and operational stability.

6. Lubrication
   Though not factory-greased like “2RS” rubber-sealed variants, the 6209-2Z shields retain grease effectively during operation. For optimal performance and longevity, ensure proper lubrication during installation. The shielded design helps maintain lubrication integrity over extended periods.

Applications:

The SKF 6209-2Z is used in a broad range of industries and mechanical systems, including:

• Electric motors and generators

• Automotive components

• Industrial gearboxes and pumps

• HVAC systems

• Agricultural and construction machinery

• Textile, packaging, and conveyor systems

Its ability to accommodate radial loads, compact design, and extended service life makes it a preferred choice across diverse applications.

Advantages:

• Minimal maintenance due to efficient shielding

• Enhanced operating life through optimized geometry and surface finish

• Easy installation and interchangeability

• Quiet operation ideal for noise-sensitive applications

• Reliable sealing to prevent contamination and retain lubrication

• Versatile performance under varied temperature and load conditions

Operating Conditions:

• Temperature Range: -30°C to +120°C (can vary with lubricant)

• Misalignment tolerance: Limited, suitable for precision aligned shafts

• Mounting: Suitable for both axial and radial mounting configurations

Compliance and Quality:

SKF bearings comply with international standards such as ISO 15, ISO 281, and ISO 492. All products are rigorously tested under real-world operating conditions to ensure superior quality and performance.

The SKF 6209-2Z deep groove ball bearing is a robust and reliable choice for various mechanical applications requiring high precision, load capacity, and low-friction performance. With its shielded design, standardized dimensions, and dependable load-handling capabilities, it is an excellent solution for both OEM manufacturers and maintenance professionals. Whether used in industrial machinery or automotive systems, SKF delivers consistent performance, reduced downtime, and long-term value.
