3309 dimensions and recorded technical data

The recorded 3309 base designation measures 45×100×39.7 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from KOYO. It does not assign the same dimensions or operating ratings to every suffix.

The numeric series boundary is preserved: a longer number is not included merely because its first digits match. 34 recorded variants are listed. A dash means the value is missing, not zero.

How to compare these values

Use the displayed dimension names and original symbols. Housing length L, height H2 and flange width are not bearing outside diameter D. A catalogue width with an unverified symbol must not be assumed to be inner-ring width B or assembly width T. Open the product record for mounting dimensions and geometry.
Inch values are calculated from the recorded millimetres using 25.4 mm per inch, rounded to six decimal places. They do not change a metric bearing into an inch-series bearing. Gram values are converted from the recorded mass in kilograms.
C and C0 describe different rating conditions. They are not a single safe working-load limit and cannot replace an application load calculation.
Reference and limiting speeds are separate catalogue values. The source grease/oil context is shown where recorded. Lubricant, seals, loads, fit, clearance and cooling affect the usable operating speed.
A common base number does not prove equivalent seals, clearance, precision, material or interchangeability. Open the full designation for these fields.
