The MRC 207KS is a standard single-row deep groove ball bearing intended primarily for radial loading, while also supporting moderate axial load in both directions.

Its dimensional envelope is:

35 × 72 × 17 mm

which corresponds to the modern international bearing designation:

6207

The bearing uses a conventional non-filling-slot / Conrad-type deep groove construction, making it suitable for a wide range of industrial rotating applications.

⚙️ Applications

• Electric motors
• Pumps
• Fans and blowers
• Gearboxes
• Conveyor systems
• Industrial rollers
• Agricultural machinery
• Processing equipment
• Power-transmission systems
• General rotating machinery

🎯 Benefits

✔ Standard 35 × 72 × 17 mm dimensions

✔ Single-row deep groove design

✔ Open bearing construction

✔ Good radial-load capability

✔ Supports moderate axial load in both directions

✔ Low rolling friction

✔ Suitable for externally lubricated machinery

✔ Modern 6207 replacements are widely available

MRC 207KS → Modern 6207 Family

The dimensional relationship is:

MRC 207KS = 35 × 72 × 17 mm

which corresponds to:

6207

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

6207 Open

If the machine requires shields or seals, versions such as:

6207-2Z / 6207ZZ
or
6207-2RS

may exist, but they should not automatically replace the open 207KS because friction, lubrication, contamination protection, and speed capability differ.

Important: 207KS vs 207SZZ / 207KSFF

Do not treat different MRC suffixes as identical.

207KS
→ Basic open 100-KS-series execution

207SZZ / shielded variants
→ Protected / shielded execution

207KSFF
→ Double-side protected execution in the KS family

Even when the principal dimensions match, closure and operating characteristics can differ.

Important Cross-Reference Consideration

Before replacing MRC 207KS with a modern 6207, verify:

• Bore = 35 mm
• OD = 72 mm
• Width = 17 mm
• Open construction
• Internal clearance
• Cage
• Lubrication
• Precision class
• Speed requirement
• Load requirement
• Shaft fit
• Housing fit

(Always verify the complete marking on the original MRC 207KS before selecting SKF 6207, FAG 6207, NTN 6207, NSK 6207, or another replacement.)
