How the 6016 model number is decoded
6016 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 16 by five gives the 80 mm bore; the 125 mm outside diameter and 22 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 80 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. 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
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
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.
- Choosing the 60xx extra-light section saves radial space at 80 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 6216 before committing to the smaller envelope.
- Storage matters for open bearings: 6016 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.
- 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.
- 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.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 125 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6016.
- 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.
Are 6016 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6016 uses the same ISO 15 envelope (80×125×22 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What internal clearance does 6016 have?
Unless a clearance suffix says otherwise, 6016 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 6016 and verify the residual clearance after mounting.
How should 6016 be mounted?
Apply the mounting force to the ring being fitted: on a 80 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 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, 2RSL) differ from the industry-neutral spelling 6016.
