How the 6036-ZZ model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6036 carries bore code 36 = 180 mm. Outside diameter 280 mm and width 46 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 180 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude.
Typical equipment & failure modes
Common applications
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
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
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- Mount this 180 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 180 mm bore uses a smaller 280 mm OD than a 6236; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- ZZ shields are non-contact: 6036-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6036-2RS for that.
- Shielded 6036-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.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 280 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6036-ZZ.
- NSK catalogues the shielded version as 6036ZZ — suffix ZZ, two non-contact steel shields; the industry-neutral page spelling is -ZZ. Quote the NSK designation when ordering.
- The 198/185 kN ratings, mass 8880 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6036ZZ; this seal/size combination has no counterpart in the SKF 17000 extract used elsewhere on this site, so the page rests on a single manufacturer source — internal geometry and ratings legitimately differ between brands, so re-verify before substituting in a rated drive.
Frequently asked questions
What are the dimensions of a 6036-ZZ bearing?
A 6036-ZZ deep-groove ball bearing has a 180 mm bore, 280 mm outer diameter and 46 mm width (7.087 × 11.024 × 1.811 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
How does the 6036 bore code work?
The last two digits of 6036 are bore code 36, giving 36 × 5 = 180 mm bore. The 280 mm outside diameter and 46 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the ZZ suffix on 6036-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 6000 compare with other series at the same 180 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (280×46 mm, 50.0 mm radial section) at 180 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the NSK designation and catalogue data for 6036-ZZ?
In the NSK Rolling Bearings catalogue (E1103 Part C) this size is listed as 6036ZZ — two non-contact steel shields (NSK suffix ZZ), 180×280×46 mm per ISO 15. Quoted values: C 198 kN, C0 185 kN, mass 8880 g. The industry-neutral page spelling 6036-ZZ follows the seal-suffix convention used across this site, not NSK order-number spelling. Reference and limiting speeds are not tabulated in the E1103 dimension tables used here; consult NSK speed tables before high-speed service.
