NU1005 bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with NU1005. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

Find by measured dimensions
Enter bore d, outside diameter D and width B. Use decimals or inch fractions such as 1/2 or 1 1/4.
NU1005 dimensions and recorded technical data
The recorded NU1005 base designation measures 25×47×12 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from SKF, NSK, 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. 4 recorded variants are listed. A dash means the value is missing, not zero.
Catalogue parameters for NU1005
Choose the complete brand and marking before reading a value. These source-labelled records add dimensions, construction and engineering properties where they were recorded; a shared model number does not establish interchangeability.
Units, ranges and minimum/maximum qualifiers are retained. The data is a dated catalogue reference, not a certified drawing, a complete current specification or an operating approval.
KOYO NU1005 — 26 recorded parameters
Cylindrical roller bearing

Read the complete suffix and recorded construction. Similar dimensions do not prove identical seals, clearance, precision or material.
Values shown are retained from the recorded source. Zero boundary dimensions and zero load ratings from incomplete legacy feeds are withheld rather than presented as usable specifications.

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.
Related prefix matches — other model numbers may appear
These discovery results can contain a longer number or a different component. They are not specifications for the requested exact model. Open the complete product to inspect its original geometry.
Check the drawing before substituting
Nominal dimensions are not shaft-fit tolerances. Different variants can add grooves, flanges, wider rings or assembly components. When the table has different dimensions, the complete designation—not the shared prefix—controls.
Reference basis & data limits
Manufacturer terminology is retained in the product records. Technical reference basis: JTEKT Basic Bearing Knowledge (boundary dimensions, tolerance classes and lubrication); NSK Bearing ABCs (lubrication, designations and clearance); NTN technical FAQs (closure codes and component interchange); SKF rolling-bearing selection and maintenance references.
Selection workflows and catalogue grouping are BearingScope editorial aids. Verify the current drawing and application requirements before using a candidate. Missing database information is not converted into an assumed match.
