How the 6032-ZZ model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6032 carries bore code 32 = 160 mm. Outside diameter 240 mm and width 38 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 160 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
- industrial fans and blowers
- hoists and winches
- heavy conveyors
- pulp and paper machinery
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
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- Mount this 160 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 160 mm bore uses a smaller 240 mm OD than a 6232; 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: 6032-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6032-2RS for that.
- Shielded 6032-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.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6032-C3. No clearance suffix means normal CN clearance.
- SKF spells the shielded version 6032-2Z (one shield: 6032-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 6032-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 6032-2Z for high-contamination positions.
- The 143/143 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 6032-ZZ bearing?
A 6032-ZZ deep-groove ball bearing has a 160 mm bore, 240 mm outer diameter and 38 mm width (6.299 × 9.449 × 1.496 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
How does the 6032 bore code work?
The last two digits of 6032 are bore code 32, giving 32 × 5 = 160 mm bore. The 240 mm outside diameter and 38 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the ZZ suffix on 6032-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 160 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (240×38 mm, 40.0 mm radial section) at 160 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the SKF designation and catalogue data for 6032-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6032-2Z — two non-contact sheet-metal shields, 160×240×38 mm per ISO 15. Quoted values: C 143 kN, C0 143 kN, Pu 4.3 kN, limiting speed 2800 r/min, mass 5400 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6032-ZZ.
