The MRC (SKF) 5204SBKFF Double Row Ball Bearing is designed for rotating equipment requiring higher load capacity and greater axial support than a conventional single-row deep-groove ball bearing of similar shaft size.

The 5204 series is typically associated with a double row angular-contact-type ball bearing arrangement, effectively providing two rows of rolling elements in one compact bearing unit. This configuration can accommodate radial loading together with axial loading acting from either direction, depending on the exact bearing execution.

Nominal dimensions:

Bore Diameter: 20 mm

Outside Diameter: 47 mm

Bearing Width: approximately 20.6 mm

Approximate inch dimensions:

Bore: 0.787 in

Outside Diameter: 1.850 in

Width: 0.811 in

The supplied designation includes the suffix SBKFF. Because suffix conventions are manufacturer-specific, this code should be preserved exactly when sourcing a replacement. Do not select a substitute solely from the basic 5204 number without checking the complete suffix and construction.

For replacement work, verify:

• Complete bearing designation
• Sealing or shielding arrangement
• Internal clearance or preload
• Cage configuration
• Lubrication
• Shoulder and fillet dimensions
• Shaft and housing fits
• Speed requirement
• Operating temperature
• Axial and radial load conditions

⚙️ Applications

• Electric motors
• Industrial gearboxes
• Pumps
• Machine-tool assemblies
• Conveyor equipment
• Agricultural machinery
• Industrial drive systems
• Transmission assemblies
• Fans and rotating machinery
• OEM industrial equipment

🎯 Benefits

✔ Double-row ball-bearing construction

✔ Supports combined radial and axial loading

Model / Bearing Number: 5204SBKFF

Bearing Series: 5204

Bearing Type: Double Row Ball Bearing

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

Bore Diameter (d): 20 mm

Outside Diameter (D): 47 mm

Width (B): Approximately 20.6 mm

Inch Equivalent: Approximately 0.787 × 1.850 × 0.811 in

Rolling Elements: Ball

Number of Rows: 2

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

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

Seal / Shield: Verify from the complete SBKFF designation and actual bearing construction

Cage: Verify actual MRC 5204SBKFF specification

Internal Clearance / Preload: Verify actual manufacturer specification

Lubrication: Verify whether the supplied execution is factory-lubricated and whether relubrication is permitted or required

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

Temperature Range: Depends on lubricant, seals if fitted, cage material, and operating conditions

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• MRC 5204SBKFF
• MRC 5204 Series Double Row Bearing
• SKF-Compatible 5204 Series Bearing
• 20x47x20.6 mm Double Row Ball Bearing
• 5204 Double Row Angular Contact Bearing
• 20 mm Bore Double Row Bearing
• Industrial 5204 Bearing
• Double Row Radial / Axial Ball Bearing
• OEM 5204-Series Replacement Bearing
• Industrial Double Row Ball Bearing

A bearing with the same 20 × 47 × 20.6 mm dimensions is not automatically interchangeable. The replacement should also match the complete suffix, contact-angle arrangement, sealing or shielding, internal clearance/preload, cage, lubrication, shoulder dimensions, load ratings, speed capability, and operating environment.

(Always verify the complete MRC 5204SBKFF designation and manufacturer specification before ordering a substitute.)
