How the 6000-ZZ model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6000 carries bore code 00 = 10 mm. Codes 00–03 follow the 10/12/15/17 mm exception table rather than code × 5. Outside diameter 26 mm and width 8 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 10 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 6000-2Z.
Typical equipment & failure modes
Common applications
- fractional-horsepower electric motors
- domestic appliances
- power tools
- small 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
- Miniature bearings like 6000-ZZ (10 mm bore) brinell under surprisingly small pressing force; use a fitting sleeve on the ring being mounted and never let the assembly load cross the balls.
- The 60xx extra-light section at 10 mm bore uses a smaller 26 mm OD than a 6200; 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: 6000-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6000-2RS for that.
- Shielded 6000-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.
- Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
- Vibration during standstill brinells the raceways of a 10 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- SKF spells the shielded version 6000-2Z (one shield: 6000-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 6000-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 6000-2Z for high-contamination positions.
- The 4.75/1.96 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 6000-ZZ bearing?
A 6000-ZZ deep-groove ball bearing has a 10 mm bore, 26 mm outer diameter and 8 mm width (0.394 × 1.024 × 0.315 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
How should 6000-ZZ be mounted?
Apply the mounting force to the ring being fitted: on a 10 mm shaft seat the press load must pass through the inner-ring face only. A fitting sleeve and an arbor press are normally sufficient at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 6000-ZZ need?
6000-ZZ is greased at the factory and the shields hold the fill for the bearing's service life; relubrication is not intended, and adding grease through the shield gap usually forces dirt in with it.
Why does 6000 not follow the bore-code × 5 rule?
Codes 00–03 use the exception table (10, 12, 15 and 17 mm): 6000 with code 00 has a 10 mm bore. The code × 5 convention starts at code 04 (20 mm).
What is the SKF designation and catalogue data for 6000-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6000-2Z — two non-contact sheet-metal shields, 10×26×8 mm per ISO 15. Quoted values: C 4.75 kN, C0 1.96 kN, Pu 0.083 kN, limiting speed 34000 r/min, mass 20 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6000-ZZ.
