The 54kg difference represents about 4% overload, which can reduce bearing life by 20-30% in continuous heavy-duty operation. Heavy machinery requires reliable performance with adequate safety margins.
How To Handle It
Consider 6007 or 6206 series for loads approaching 1400kg. If space constraints require 6006, ensure perfect alignment, premium lubrication, eliminate shock loads, and implement continuous condition monitoring for early problem detection.
Always maintain 15-20% safety margin for heavy machinery - for 1400kg loads, specify bearings rated at least 1650kg capacity.

What's the difference between 6006 and smaller 6005 bearings?

6006 has 30mm bore vs 6005's 25mm bore, providing significantly higher load capacity with increased width.
Why This Matters
The 5mm bore increase provides substantially higher load capacity (1346kg vs 1020kg) with 1mm additional width (13mm vs 12mm). This makes 6006 ideal for applications requiring higher loads on 30mm shafts with minimal size increase. The capacity improvement is excellent for the modest size increase.
How To Handle It
Evaluate shaft size requirements - 30mm shafts are common in heavy industrial equipment. Compare load requirements against the substantial capacity difference. Consider the minimal width increase impact on available space and mounting requirements.
6006 provides 32% higher load capacity than 6005 with only 8% width increase - excellent performance scaling.

Is 6006 suitable for 30mm heavy automotive transmission shafts?

Excellent choice for heavy automotive transmissions requiring reliable performance on 30mm shafts.
Why This Matters
Heavy automotive transmissions subject bearings to high loads, speeds, temperature cycles, and continuous operation.

When should I pay more for bearings rated above 11000 RPM?

Only when operating speeds regularly exceed 9900 RPM or require speed capability for equipment optimization.
Why This Matters
Higher speed ratings require tighter tolerances and premium materials, increasing cost significantly. The 11000 RPM rating handles most heavy-duty industrial applications effectively without premium cost. Overpaying for unnecessary speed capability reduces value in heavy-duty applications.
How To Handle It
Analyze actual operating speeds including all conditions and future requirements. Consider equipment upgrade plans and optimization needs. Compare premium cost against specific performance benefits and equipment lifecycle requirements in heavy-duty use.
Specify speed rating 10-15% above normal operating speed - provides adequate safety without unnecessary cost premium in heavy applications.

What's the cost difference between 6006 and larger 6007 bearings?

6007 costs 25-35% more than 6006 but provides higher load capacity for 35mm vs 30mm shafts.
Why This Matters
Size progression involves moderate cost increases but provides substantial capacity improvements. The 5mm shaft size difference may require design modifications but offers significant load capacity increase. Understanding cost scaling helps optimize selection within design and budget constraints.
How To Handle It
Compare application load requirements against shaft size modification requirements. Evaluate if design changes for larger shaft are justified by improved bearing capacity and reliability. Consider standardization benefits within equipment product lines for heavy-duty applications.
