EZO 6907 dimensions and model reference

EZO 6907 is listed as a thin-section ball bearing with a 35 mm bore, 55 mm body outside diameter and 10 mm inner-ring width B. Its outer-ring width C is 10 mm.

Basic dynamic radial rating Cr: 10.9 kN; basic static radial rating C0r: 7.75 kN. Reference mass: 69.2 g.

How to compare this exact model

  • The shorthand 35×55×10 mm uses d×D×B. Keep C separately when comparing ring seating or axial envelopes; B and C are not interchangeable labels.
  • The exact catalogue marking identifies open (no closure suffix in this catalogue marking). Material interpretation: high-carbon chromium bearing steel. These interpretations use EZO’s code system, not a universal cross-brand suffix rule.
  • The original metric and inch entries are both retained as published. Their rounding may differ from a calculation using extra decimal places; do not treat the displayed decimals as a tolerance.
  • Cr and C0r are radial rating inputs, not a universal safe working load. An application still needs its actual load, speed, life, mounting and lubrication conditions checked.
  • Grease and oil limits are shown separately. They are catalogue reference conditions, not a guaranteed operating speed for every seal, cage, temperature, cooling arrangement or rotating ring.
  • The table does not establish your ordered precision class, internal clearance, grease fill or cage option. An ABEC grade or C3 clearance must not be supplied from a nearby model.
  • Equal dimensions do not certify machine, bicycle, vehicle or other equipment fitment. Keep the complete brand and suffix when comparing candidates.
