NU 210 bearing dimensions & suffix variants

Look up recorded dimensions for designations beginning with NU 210. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

On this page5 sections

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.

For tapered assemblies use total width T; for units or flanged bearings also check the mounting drawing.

Exact model evidence

NU 210 dimensions and recorded technical data

The recorded NU 210 base designation measures 50×90×20 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from NTN. 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. 31 recorded variants are listed. A dash means the value is missing, not zero.

Exact designation reference

Catalogue parameters for NU 210

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.

NTN NU210 — 24 recorded parameters

Single row cylindrical roller bearings

Reference: NTN Europe public product catalogue; source snapshot 2026-10-02.

For this exact NTN NU210 record, the nominal envelope is 50×90×20 mm (d = internal diameter; D = external diameter; B = bearing/inner ring width). These are bearing or washer dimensions, not shaft/housing fit limits.

Calculated inch equivalent: 1.968504×3.543307×0.787402 in, in the same axis order. The conversion uses exactly 25.4 mm per inch and rounds to six decimals; it is not an inch-series designation or a machining tolerance.

Keep the prefix when matching this cylindrical roller bearing. The source construction below, including any axial-load direction statement, belongs only to the complete recorded designation; a similar NU, NJ or NUP number is not an approved substitute.

Use grease- and oil-qualified speed entries only for the named lubrication condition. Dynamic C and static C0 are catalogue ratings, not a universal safe load or installation approval; shoulder and fillet limits are separate from boundary size.

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.

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.
