How the 6016-ZZ model number is decoded
In the 6000-series (diameter series 0 of ISO 15) 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. 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 80 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's own suffix is 2Z (this page's industry-neutral spelling is -ZZ); catalogue number 6016-2Z.
Typical equipment & failure modes
Common applications
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
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
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- At 80 mm bore the ring mass is significant: heat 6016 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 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.
- ZZ shields are non-contact: 6016-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6016-2RS for that.
- Do not wash 6016-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.
- 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-ZZ.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- SKF spells the shielded version 6016-2Z (one shield: 6016-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 6016-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 6016-2Z for high-contamination positions.
- 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-ZZ bearing?
A 6016-ZZ 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 fitted with two non-contact metallic 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. Seal suffixes also differ by brand (2RS, DDU, LLU, 2RSL and similar).
What internal clearance does 6016-ZZ have?
Unless a clearance suffix says otherwise, 6016-ZZ 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-ZZ 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-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6016-2Z — two non-contact sheet-metal shields, 80×125×22 mm per ISO 15. Quoted values: C 49.4 kN, C0 40 kN, Pu 1.66 kN, limiting speed 5600 r/min, mass 890 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6016-ZZ.
