The MRC (SKF) 206SFFC is a single-row deep groove ball bearing designed with a special extra-wide section commonly described as Cartridge Width.

While a standard 6206-series bearing uses the same nominal 30 mm bore and 62 mm OD, the 206SFFC has a much greater width of approximately:

23.8125 mm / 15/16 inch

This wider construction is important in machinery where the bearing, shaft shoulder, housing depth, retaining arrangement, and axial positioning were specifically designed around the original MRC cartridge-width bearing.

The bearing combines three important characteristics:

1. Single-Row Deep Groove Construction
The bearing uses a standard deep-groove raceway arrangement suitable primarily for radial loads while also providing moderate axial-load capability in both directions under suitable operating conditions.

2. Double Metal Shields – FF
Metal shields are installed on both sides of the bearing. These help retain lubricant inside the bearing and reduce contamination from dust and dirt while maintaining relatively low friction.

3. C3 Internal Clearance – C
The C suffix indicates increased internal clearance relative to normal clearance. This extra internal running clearance is useful in applications involving elevated operating temperatures, higher rotational speeds, tighter shaft fits, or conditions where thermal expansion can reduce bearing clearance during operation.

Before replacement, verify the full 206SFFC configuration rather than selecting only by bore and OD.

Bore Diameter (d): 30 mm

Outside Diameter (D): 62 mm

Width (B): 23.8125 mm

Width in Inches: 15/16 in / 0.9375 in

Approx. Inch Dimensions: 1.181 × 2.441 × 0.938 in

Rolling Elements: Ball

Number of Rows: 1

Raceway Type: Deep Groove

Section Type: Cartridge Width / Extra-Wide

Suffix S: Single-row deep groove / symmetrical ring configuration

Suffix FF: Double Metal Shields

Suffix C: C3 Internal Clearance

Closure Type: Metal shields on both sides

Internal Clearance: C3 – greater than normal internal clearance

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

Contamination Protection: Metal shields help reduce entry of dust and dirt while retaining lubricant

Lubrication: Shielded bearing configuration; verify grease condition and compatibility for the specific application

Speed Consideration: C3 clearance can be advantageous where thermal expansion or higher speed would otherwise reduce running clearance

Temperature Consideration: Increased internal clearance can help accommodate thermal growth, but actual allowable temperature depends on lubricant, cage, fit, and operating environment

Shaft Fit: Nominal 30 mm shaft; verify shaft tolerance and interference

Housing Fit: Nominal 62 mm housing bore; verify housing tolerance and shoulder configuration

Installation Consideration: The 23.8125 mm cartridge width must match the original housing depth, shaft shoulder, retaining system, and available axial space

Standard: Manufacturer-Specific MRC Cartridge-Width Deep Groove Bearing

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• MRC 206SFFC
• MRC 206SFF C3
• 30x62x23.8125 mm Deep Groove Ball Bearing
• 30x62x15/16 in Ball Bearing
• Cartridge-Width 206 Bearing
• Double-Shielded C3 Bearing
• 30 mm Bore Industrial Ball Bearing
• 62 mm OD Cartridge Bearing
• Legacy MRC 206 Series Bearing
• Industrial Extra-Wide Deep Groove Bearing

A conventional 6206 bearing should not automatically be considered a direct replacement simply because it shares the same 30 mm bore and 62 mm outside diameter.

The critical difference is the 23.8125 mm cartridge width, which affects:

• Shaft shoulder position
• Housing depth
• Spacer location
• Retaining rings
• Axial positioning
• Assembly preload/end-play
• Adjacent components

The replacement should also match the double-shielded construction, C3 clearance, cage, lubrication, load rating, speed capability, shaft fit, housing fit, and operating environment.

(Always verify the complete MRC 206SFFC dimensions and machine mounting arrangement before substituting another bearing.)
