The MRC (SKF) 207SZZ is a standard-size single-row deep groove ball bearing designed around the dimensional envelope:

35 × 72 × 17 mm

Equivalent inch dimensions are approximately:

1.3780 × 2.8346 × 0.6693 in

Its deep-groove raceway geometry provides an effective combination of:

• Radial-load carrying capability
• Moderate axial-load capability in both directions
• Low rolling friction
• High rotational-speed capability
• Compact bearing construction
• Long service life when correctly fitted and lubricated

The double metal shields help prevent coarse dust and foreign particles from reaching the rolling elements while retaining grease inside the bearing.

Because metal shields are generally non-contact or low-drag closures, they provide better high-speed characteristics than many contact-rubber sealing systems.

⚙️ Applications

• Electric motors
• Industrial pumps
• Gearboxes
• Fans and blowers
• Conveyor drive systems
• Machine tools
• Mechanical transmissions
• Agricultural machinery

Basic Dynamic Radial Load Rating (C): Approximately 25,500 N / 25.5 kN

Basic Static Radial Load Rating (C₀): Approximately 15,300 N / 15.3 kN

Limiting Speed: Approximately 9,500 rpm with grease under suitable operating conditions

Load Capability: Primarily radial load with moderate axial-load capability in both directions

Axial Load Direction: Both directions within bearing and application limits

Contamination Protection: Metal shields help exclude coarse dust and foreign particles

Lubrication Retention: Double shields help retain grease inside the bearing

Lubrication: Typically grease-lubricated shielded configuration; verify actual lubricant where critical

Internal Clearance: Not defined by 207SZZ alone; verify whether Normal, C3, or another clearance applies

Cage: Verify original MRC specification

Temperature Range: Depends on lubricant, cage, clearance, fit, speed, and operating environment

Shaft Fit: Nominal 35 mm shaft; verify shaft tolerance and interference

Housing Fit: Nominal 72 mm housing bore; verify housing tolerance and shoulder geometry

Installation Consideration: Confirm shaft/housing fits, shield condition, clearance, lubrication, alignment, and operating speed before installation

Dimensional Standard: 35 × 72 × 17 mm Deep Groove Ball Bearing Envelope

🔁 Equivalent

Suitable replacement or cross-reference candidates include:

• MRC 207SZZ
• SKF 6207-2Z
• SKF 6207ZZ market designation
• NSK 6207ZZ
• NTN 6207ZZ
• KOYO 6207ZZ
• FAG 6207-2Z
• 35x72x17 mm Double-Shielded Ball Bearing
• 35 mm Bore Deep Groove Bearing
• Industrial 6207-2Z Replacement Bearing

Cross-Reference Comparison

These are strong dimensional and construction cross-reference candidates, but “same size” should not by itself be interpreted as guaranteed 100% interchangeability.

Before substitution, also confirm:

• Internal clearance
• Dynamic and static load ratings
• Cage construction
• Grease specification
• Precision class
• Speed rating
• Shield geometry
• Shaft fit
• Housing fit
• Operating temperature

For example, a 6207-2Z/C3 should not automatically replace a Normal-clearance bearing unless the machine application requires C3.

(Always verify the complete original MRC 207SZZ specification and operating requirements before selecting a modern replacement.)
