How the 6016-2RS 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. Suffix -2RS denotes two contact-type elastomer seals over a lifetime grease fill; the sealing lips add drag compared with open or shielded versions. 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 contact-seal catalogue number is 6016-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.
Typical equipment & failure modes
Common applications
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
Known failure patterns
- seal-lip hardening and loss of pre-grease in sustained high-temperature service
- grease-life expiry in the sealed-for-life cavity (no relubrication path)
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
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.
- Contact seals add drag and heat: 6016-2RS runs slower and cooler-limited than the open 6016; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
- Never wash a sealed 6016-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- 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 6016-2RS.
- SKF catalogues the contact-sealed version as 6016-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 3200 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 11000 r/min thermal reference speed. The single-seal catalogue number is 6016-RS1, used where one shaft side needs external relubrication.
- A one-seal execution 6016-RS1 exists for arrangements that lubricate through the open side; fitting 6016-2RS1 instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
- 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 6016-2RS bearing?
A 6016-2RS 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 contact rubber seals and is normally pre-greased. 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 the 2RS suffix on 6016-2RS mean?
2RS means two contact elastomer seals, one each side, usually over a lifetime grease fill. Sealing against dust and moisture is better than ZZ shields, but the lip drag lowers the speed and temperature ceiling.
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 6016-2RS?
In the SKF Rolling Bearings catalogue this size is listed as 6016-2RS1 — two contact elastomer seals over a lifetime grease fill, 80×125×22 mm per ISO 15. Quoted values: C 49.4 kN, C0 40 kN, Pu 1.66 kN, limiting speed 3200 r/min, mass 880 g. Brand suffixes (2Z, 2RSH) differ from the industry-neutral spelling 6016-2RS.
