NUTR40 bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with NUTR40. 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.
NUTR40 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. 3 recorded variants are listed. A dash means the value is missing, not zero.
Catalogue parameters for NUTR40
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.
INA NUTR40 — 17 recorded parameters
Yoke type track roller
Reference: Schaeffler medias — INA; source snapshot 2026-10-03.
NUTR40 is a yoke-type track roller with a 40 mm bore, 80 mm outside diameter and 32 mm bearing width. The outer-ring width C is 30 mm.
The current manufacturer record identifies NUTR40 and describes the NUTR..-A construction: two full-complement cylindrical-roller rows, an inner ring and labyrinth seals. The older page-address suffix is not used to infer a different product.
Cr w and C0r w are rating values. Fr per and F0r per are separately listed permissible outer-ring loads; do not substitute one for the other. The stated grease speed is not a guaranteed operating speed for every track or lubrication condition.
Manufacturer product identity and parameters checked on 2026-10-03. A catalogue reference is not a certified drawing or an application approval.

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.

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.
