NU 317 dimensions and recorded technical data

Use the named dimensions for each complete record below. A generic d×D×B answer is not asserted where the base record is missing, dimension symbols are unverified, or the product uses a different geometry such as a housing or thrust assembly. Suffix records are not substituted for a missing base specification.

The numeric series boundary is preserved: a longer number is not included merely because its first digits match. 16 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.
