How the 6026-ZZ model number is decoded
6026-ZZ carries two non-contact sheet-steel shields that hold the factory grease in and keep coarse debris out; they do not seal against liquids. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 26 by five gives the 130 mm bore; the 200 mm outside diameter and 33 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 130 mm shaft under normal load, catalogue practice seats it on a m6 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. SKF's own suffix is 2Z (this page's industry-neutral spelling is -ZZ); catalogue number 6026-2Z.
Typical equipment & failure modes
Common applications
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
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
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- brinelling from static overload or hammering during mounting
Selection pitfalls — read before you substitute
- At 130 mm bore the ring mass is significant: heat 6026 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.
- Choosing the 60xx extra-light section saves radial space at 130 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6226 before committing to the smaller envelope.
- Do not wash 6026-ZZ 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 6026-ZZ units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
- Do not quieten a noisy bearing by preloading it: the 6000-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
- Vibration during standstill brinells the raceways of a 130 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- SKF spells the shielded version 6026-2Z (one shield: 6026-Z), not "-ZZ": the suffix language differs by brand even though the ISO envelope is identical, so quote the brand designation when ordering.
- The single-shield execution 6026-Z is a distinct order number in catalogue 17000: it suits open gears or oil-bath arrangements where the unshielded face faces the lubricant, and it is not interchangeable with the double-shield 6026-2Z for high-contamination positions.
- The 112/100 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6026-ZZ bearing?
A 6026-ZZ deep-groove ball bearing has a 130 mm bore, 200 mm outer diameter and 33 mm width (5.118 × 7.874 × 1.299 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
What does the ZZ suffix on 6026-ZZ mean?
ZZ means two non-contact sheet-metal shields, one each side. They retain factory grease and block coarse particles with little friction, but do not seal against liquids, fine dust or pressure washing.
How does the 6000 compare with other series at the same 130 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (200×33 mm, 35.0 mm radial section) at 130 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6026 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6026 uses the same ISO 15 envelope (130×200×33 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 is the SKF designation and catalogue data for 6026-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6026-2Z — two non-contact sheet-metal shields, 130×200×33 mm per ISO 15. Quoted values: C 112 kN, C0 100 kN, Pu 3.35 kN, limiting speed 3400 r/min, mass 3350 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6026-ZZ.
