How the 6226-ZZ-FAG model number is decoded

In the 6200-series (diameter series 2 of ISO 15) the last two digits encode the bore: 6226 carries bore code 26 = 130 mm. Outside diameter 230 mm and width 40 mm come from the ISO 15 boundary-dimensions general plan. Suffix -ZZ denotes two non-contact metallic shields; they retain grease and block coarse debris but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 130 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. Schaeffler HR 1 catalogue order number: 6226-2Z (FAG suffix 2Z), two non-contact steel shields, mapped here from the industry-neutral -ZZ spelling.

Typical equipment & failure modes

Common applications

  • medium and heavy industrial drives
  • large gearboxes
  • industrial fans and blowers
  • hoists and winches

Known failure patterns

  • fine-particle abrasion when non-contact shields let dust past in dirty duty
  • grease aging in the shield-for-life cavity with no relubrication path
  • brinelling from static overload or hammering during mounting
  • false brinelling from vibration while the shaft is stationary

Selection pitfalls — read before you substitute

  • At 130 mm bore the ring mass is significant: heat 6226 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
  • At 130 mm bore the 62xx light series is the workhorse section; its 230×40 mm envelope is what most motor and gearbox seats are machined for, so any alternative section must be checked against both this OD and this width, not the bore alone.
  • Do not wash 6226-ZZ-FAG in solvent before mounting: the grease inside the shielded cavity is the service fill, and solvent creeping past the shield gap strips it out.
  • Shielded 6226-ZZ-FAG units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
  • Measure the shaft, do not trust the drawing: a 130 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6226-ZZ-FAG.
  • Never mix components between two 6226-ZZ-FAG units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
  • Schaeffler HR 1 lists the shielded version as 6226-2Z — FAG suffix 2Z, two non-contact steel shields. The industry-neutral page spelling is -ZZ; quote the FAG order number when buying through a Schaeffler channel.
  • FAG lists the mechanical limiting speed at 3250 r/min for 6226 (thermal reference speed 3900 r/min); the thermal reference speed is the binding figure for continuous duty — size the lubrication interval off the reference speed, not the mechanical limit.
  • The 130 mm bore places 6226 at the lower end of Schaeffler's large-size range; at these diameters the pressed steel cage is speed-limited and FAG commonly offers a machined brass cage (suffix M) as an option. Verify cage material and relubrication provision with the distributor, and do not extrapolate small-bore speed ratings to this size.
  • FAG rates 6226 at 177 kN dynamic (C) and 146 kN static (C0); this is an extreme-load rating at the top of the HR 1 single-row deep-groove range, where mounting, shaft stiffness and housing alignment dominate achievable life — request a Schaeffler application review rather than relying on catalogue L10 alone.
  • At 6120 g (6.1 kg), 6226 is a heavy FAG bearing that requires a crane or hoist for handling; induction-heat the inner ring (max 120 °C) and use a mechanical puller for removal — never apply heat directly to the balls or cage.
  • The 130×230×40 mm envelope of 6226 gives a D/d ratio of 1.77 and 50.0 mm radial section height — a standard FAG medium section balancing load capacity and speed; the standard cage is adequate up to the listed speeds and C3 clearance is the common hot-shaft choice.
  • The 177/146 kN load ratings, mass 6120 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 6226-2Z on the 130×230×40 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6226 in a rated drive. Where FAG has since released an X-life version of this size, its expanded C/C0 ratings supersede the HR 1 print values quoted here.
  • FAG standard tolerance for this size is P0 (PN); P6/P5 precision executions exist for spindle-adjacent duty but carry different order numbers in the Schaeffler system — they are not a selectable sorting of standard stock.
  • Mixing old and new FAG generations of the same designation in one arrangement is dimensionally acceptable, but where ratings matter — preloaded or matched sets — order both positions from the same generation and lot.

Frequently asked questions

What are the dimensions of a 6226-ZZ-FAG bearing?

A 6226-ZZ-FAG deep-groove ball bearing has a 130 mm bore, 230 mm outer diameter and 40 mm width (5.118 × 9.055 × 1.575 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.

Are 6226 bearings from different brands interchangeable?

For boundary dimensions, yes: every brand's 6226 uses the same ISO 15 envelope (130×230×40 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting. Seal suffixes also differ by brand (2RS, DDU, LLU, 2RSL and similar).

What internal clearance does 6226-ZZ-FAG have?

Unless a clearance suffix says otherwise, 6226-ZZ-FAG is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6226 and verify the residual clearance after mounting.

What is the FAG suffix for a sealed 6226?

FAG uses suffix 2RSR for the lip-contact rubber seal (catalogue number 6226-2Z), 2RZ for the non-contact rubber seal and 2Z for steel shields. The industry-neutral spellings on this page (-2RS / -RSR / -ZZ) map to those FAG suffixes while keeping the 130×230×40 mm ISO 15 envelope.

Does FAG offer 6226 with C3 clearance?

FAG lists C3 internal clearance for most deep-groove sizes (suffix C3 follows the seal code); choose C3 for tight fits or hot shafts and stay with the standard CN clearance of 6226-2Z for normal duty.
