The MRC 122KS is a large extra-light-series deep groove ball bearing designed primarily for radial loading, while also supporting moderate axial loads in both directions.

Its dimensional envelope is:

110 × 170 × 28 mm

which corresponds to the modern standardized:

6022

The bearing uses a conventional single-row, non-filling-slot / Conrad-type deep groove construction, providing low friction and good high-speed capability relative to heavier bearing series of similar bore size.

⚙️ Applications

• Large electric motors
• Industrial pumps
• Fans and blowers
• Gearboxes
• Conveyor systems
• Processing machinery
• Industrial rollers
• Agricultural machinery
• Power-transmission equipment
• General rotating machinery

🎯 Benefits

MRC 122KS → Modern 6022 Family

The dimensional relationship is:

MRC 122KS = 110 × 170 × 28 mm

which corresponds to:

6022

For an original open bearing, the closest modern starting point is:

6022 Open

If the operating environment requires a different closure, shielded or sealed 6022 variants may exist depending on manufacturer, but they should not automatically replace the open 122KS without checking speed, lubrication, and temperature requirements.

Important: 122KS vs 122KSFF

The suffix is important.

122KS
→ Base 100-KS-series bearing, typically open execution

122KSFF
→ Protected on both sides / typically double-shielded MRC execution

Therefore, 122KS and 122KSFF should not automatically be treated as identical, even though their basic dimensions may match.

Important Cross-Reference Consideration

Before replacing MRC 122KS with a modern 6022, verify:

• Bore = 110 mm
• OD = 170 mm
• Width = 28 mm
• Open construction
• Internal clearance
• Cage construction
• Lubrication method
• Precision class
• Operating speed
• Load requirements
• Shaft fit
• Housing fit

(Always verify the complete marking on the original MRC 122KS before selecting SKF 6022, FAG 6022, NTN 6022, NSK 6022, or another replacement.)
