6218 — PEER catalogue dimensions

Independent technical reference from PEER’s historical 2009 sheets; checked 2026-10-03. These are catalogue records, not current-stock claims or replacement approvals. Printed units are kept separate.

Read ratings without transferring them to another execution

Cr and Cor are catalogue basic load ratings, not allowable application loads. Oil/grease values below are explicitly for open bearings where supplied. They are not sealed-bearing or machine operating-speed approvals. A dash means withheld or not established here.

Published PEER ratings — N and r/min
Model	Dynamic Cr / static Cor	Open: oil / grease	Evidence boundary
6218	—	4700 / 4000 r/min	Load ratings withheld because the printed N/lbf pair needs verification.

Printed decimal conversions inherit catalogue rounding; more decimal places do not create manufacturing accuracy. Special bores must not be rounded to a nearby metric bearing. The historical table does not establish an exact RS/2RS, NR, ABEC, C3, ceramic, vehicle or kit execution unless explicitly listed. No CAD or interchange approval is implied.

6218 dimensions and recorded technical data

The recorded 6218 base designation measures 90×160×30 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from SKF, FAG, 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. 78 recorded variants are listed. A dash means the value is missing, not zero.

Boundary size alone does not describe every ring, shoulder or assembled unit. These tables retain the recorded manufacturer labels, symbols, units and limits for each complete marking. Expand a record to check its detailed measurements.

Important: an approximate value, a minimum or a maximum keeps that qualifier. These reference extracts are not CAD drawings, fit recommendations or replacement approvals.

Metric and inch measurements below are the values published together in this dated manufacturer record. Their displayed rounding is retained; the inch column does not turn a metric design into an inch-series design.

Keep the full marking shown for this record. Equal nominal dimensions do not establish matching closure, clearance, precision, material or operating limits.

Shaft and housing backing-shoulder dimensions, maximum fillet radii and signed offsets answer different installation questions. Preserve the named face, limit and sign; they are not additional bearing outside diameters or nominal widths.

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.
