How the 6016 model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6016 carries bore code 16 = 80 mm. Outside diameter 125 mm and width 22 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 80 mm shaft, typical catalogue practice is a k5 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
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- 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
- Mount this 80 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 60xx extra-light section at 80 mm bore uses a smaller 125 mm OD than a 6216; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- The open 6016 has no lubricant retention: grease escapes and contaminants migrate straight into the 80×125×22 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6016 units.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6016-C3. No clearance suffix means normal CN clearance.
- The open 6016 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6016-2Z (shields) and 6016-2RSH (contact seals), not suffix-free 6016.
- The 49.4/40 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 6016 bearing?
A 6016 deep-groove ball bearing has a 80 mm bore, 125 mm outer diameter and 22 mm width (3.15 × 4.921 × 0.866 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields. Geometry-based estimated mass is about 813 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
How does the 6016 bore code work?
The last two digits of 6016 are bore code 16, giving 16 × 5 = 80 mm bore. The 125 mm outside diameter and 22 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 6016 mean?
A bare 6016 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 6000 compare with other series at the same 80 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (125×22 mm, 22.5 mm radial section) at 80 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the SKF designation and catalogue data for 6016?
In the SKF Rolling Bearings catalogue this size is listed as 6016 — the open (unsealed) execution, 80×125×22 mm per ISO 15. Quoted values: C 49.4 kN, C0 40 kN, Pu 1.66 kN, limiting speed 7000 r/min, mass 860 g. Brand suffixes (2Z, 2RSH) differ from the industry-neutral spelling 6016.
