The MRC (SKF) 5209 Double Row Ball Bearing is designed for rotating equipment requiring greater load capacity, rigidity, and axial-load support than a conventional single-row ball bearing of similar shaft diameter.

The 5209 series typically incorporates two rows of balls arranged in a double-row angular-contact configuration. This design can support radial loading together with axial loading from both directions and can provide improved shaft-location capability in a relatively compact bearing assembly.

Nominal dimensions:

Bore Diameter: 45 mm

Outside Diameter: 85 mm

Bearing Width: approximately 30.2 mm

Approximate inch dimensions:

Bore: 1.772 in

Outside Diameter: 3.346 in

Width: 1.189 in

Because the supplied designation is simply 5209, replacement selection should not be based on the basic number and dimensions alone. Additional suffixes may define important characteristics such as seals, shields, clearance, preload, cage material, lubrication, or other manufacturer-specific execution.

Before selecting a replacement, verify:

• Complete bearing designation
• Seal or shield arrangement
• Internal clearance or preload
• Cage configuration
• Lubrication
• Contact-angle arrangement
• Shaft and housing fits
• Radial and axial load requirements
• Operating speed
• Operating temperature

⚙️ Applications

• Industrial gearboxes
• Electric motors
• Industrial pumps
• Machine-tool assemblies
• Mechanical transmissions
• Conveyor drive systems
• Agricultural machinery
• Industrial drive equipment
• Heavy rotating machinery

📊 Specifications

Brand: MRC (SKF)

Model / Bearing Number: 5209

Bearing Series: 5209

Bearing Type: Double Row Ball Bearing

Typical Bearing Arrangement: Double Row Angular Contact Type; verify exact MRC execution

Bore Diameter (d): 45 mm

Outside Diameter (D): 85 mm

Width (B): Approximately 30.2 mm

Inch Equivalent: Approximately 1.772 × 3.346 × 1.189 in

Rolling Elements: Ball

Number of Rows: 2

Load Capability: Radial and axial load capability; exact ratings depend on manufacturer-specific execution

Axial Load Direction: Typically supports axial load in both directions in a double-row angular-contact arrangement

Seal / Shield: Not indicated by the supplied 5209 designation; verify actual bearing

Cage: Verify actual MRC 5209 specification

Internal Clearance / Preload: Verify manufacturer specification

Lubrication: Verify whether the supplied bearing is open, factory-lubricated, sealed, or requires external lubrication

Speed Rating: Depends on bearing execution, lubrication, load, fit, temperature, and operating conditions

Temperature Range: Depends on lubricant, sealing arrangement, cage material, and operating environment

Shaft Fit: Select according to shaft rotation, load direction, and manufacturer recommendations

Housing Fit: Select according to load, temperature, housing material, and application requirements

Standard: Metric 5209-Series Double Row Bearing

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• MRC 5209 Double Row Bearing
• MRC 5209 Ball Bearing
• SKF-Compatible 5209 Series Bearing
• 45x85x30.2 mm Double Row Ball Bearing
• 5209 Double Row Angular Contact Bearing
• 45 mm Bore Double Row Bearing
• Industrial 5209 Bearing
• Double Row Radial / Axial Ball Bearing
• OEM 5209-Series Replacement Bearing
• Industrial Double Row Ball Bearing

A bearing with the same 45 × 85 × 30.2 mm dimensions is not automatically interchangeable. The replacement should also match the contact-angle arrangement, internal clearance or preload, seal/shield configuration, cage, lubrication, load rating, speed capability, shaft fit, housing fit, and operating environment.

If the original bearing includes a suffix beyond 5209, that suffix should be preserved and checked before substitution.

(Always verify the complete MRC 5209 bearing designation and manufacturer specification before ordering a replacement.)
