How the 6026 model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6026 carries bore code 26 = 130 mm. Outside diameter 200 mm and width 33 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. 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. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- hoists and winches
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Large bores like the 130 mm of 6026 demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
- The 60xx extra-light section at 130 mm bore uses a smaller 200 mm OD than a 6226; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- The open 6026 has no lubricant retention: grease escapes and contaminants migrate straight into the 130×200×33 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6026 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- 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.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6026-C3. No clearance suffix means normal CN clearance.
- The open 6026 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6026-2Z (shields) and 6026-2RSH (contact seals), not suffix-free 6026.
- 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 bearing?
A 6026 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 an open bearing with no seals or shields.
How should 6026 be mounted?
Apply the mounting force to the ring being fitted: on a 130 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 6026 need?
The open 6026 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
How does the 6026 bore code work?
The last two digits of 6026 are bore code 26, giving 26 × 5 = 130 mm bore. The 200 mm outside diameter and 33 mm width follow the ISO 15 diameter series, not the bore code alone.
What is the SKF designation and catalogue data for 6026?
In the SKF Rolling Bearings catalogue this size is listed as 6026 — the open (unsealed) execution, 130×200×33 mm per ISO 15. Quoted values: C 112 kN, C0 100 kN, Pu 3.35 kN, limiting speed 4300 r/min, mass 3300 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6026.
