How the 6202-ZZ model number is decoded
In the 6200-series (ISO 15 diameter series 2) the last two digits encode the bore: 6202 carries bore code 02 = 15 mm. Codes 00–03 follow the 10/12/15/17 mm exception table rather than code × 5. Outside diameter 35 mm and width 11 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 15 mm shaft, typical catalogue practice is a j5 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 6202-2Z.
Typical equipment & failure modes
Common applications
- garden equipment
- instrument drives
- fractional-horsepower electric motors
- domestic appliances
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
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Bore codes 00–03 use the exception table: 6202 fits a 15 mm shaft — the code × 5 mnemonic does not apply below code 04 (it would imply 0 mm for code 00).
- The 62xx light series is the default general-purpose section at 15 mm bore; before upgrading to a 6302 for extra capacity, confirm the housing accepts a 35 mm OD and 11 mm width — it is not a drop-in swap.
- ZZ shields are non-contact: 6202-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6202-2RS for that.
- Shielded 6202-ZZ units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
- A 15 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
- SKF spells the shielded version 6202-2Z (one shield: 6202-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 6202-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 6202-2Z for high-contamination positions.
- The 8.06/3.75 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 6202-ZZ bearing?
A 6202-ZZ deep-groove ball bearing has a 15 mm bore, 35 mm outer diameter and 11 mm width (0.591 × 1.378 × 0.433 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields. Geometry-based estimated mass is about 44 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
Why does 6202 not follow the bore-code × 5 rule?
Codes 00–03 use the exception table (10, 12, 15 and 17 mm): 6202 with code 02 has a 15 mm bore. The code × 5 convention starts at code 04 (20 mm).
What does the ZZ suffix on 6202-ZZ mean?
ZZ means two non-contact sheet-metal shields, one each side. They retain factory grease and block coarse particles with little friction, but do not seal against liquids, fine dust or pressure washing.
How does the 6200 compare with other series at the same 15 mm bore?
The '2' is the light diameter series: 35×11 mm with a 10.0 mm radial section at 15 mm bore. A 6302 on the same bore is larger and higher-rated; a 6002 is smaller and lower-rated.
What is the SKF designation and catalogue data for 6202-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6202-2Z — two non-contact sheet-metal shields, 15×35×11 mm per ISO 15. Quoted values: C 8.06 kN, C0 3.75 kN, Pu 0.16 kN, limiting speed 22000 r/min, mass 48 g. Brand suffixes (2Z, 2RSH) differ from the industry-neutral spelling 6202-ZZ.
