How the 607-8-ZZ model number is decoded
In the miniature 6000-series, the bore is written directly after the slash as 8 mm (bores below 10 mm use the slash spelling). The envelope is 8×19×6 mm (0.315×0.748×0.236 in) with a 5.5 mm radial section height, C 2.34 kN, C0 0.95 kN and Pu 0.04 kN. SKF spells the double shield 607/8-2Z (suffix 2Z); the shields are non-contact, retain grease and block coarse debris but are not liquid-tight. Limiting speed 43000 r/min, catalogue mass 7.2 g.
Typical equipment & failure modes
Common applications
- office equipment
- fractional-horsepower motors
- small fans and blowers
- hand-held power tools
Known failure patterns
- fine-particle abrasion when non-contact shields let dust through in a dirty environment
- grease aging inside the shielded cavity with no relubrication path
- raceway smearing under marginal lubrication at start-up
- electrical pitting in VFD-driven motors without shaft grounding
Selection pitfalls — read before you substitute
- Do not preload 607-8-ZZ to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Assign interference to the rotating ring: on a conventional shaft-mounted 8 mm position the inner ring rotates, so use a k5/m6 shaft seat with an H7 housing — reverse the logic if the outer ring rotates.
- Shields on 607-8-ZZ are non-contact: chips and coarse dust stay out, but water passes straight through — specify the sealed 607/8-2RS for washdown duty.
- Do not pry the caps off 607-8-ZZ to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- At 8 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
- Catalogue ratings for 607-8-ZZ (C 2.34 kN, C0 0.95 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
Frequently asked questions
What are the dimensions of 607-8-ZZ?
The SKF 607/8-2Z measures 8 mm bore × 19 mm OD × 6 mm width (0.315 × 0.748 × 0.236 in), mass about 7.2 g. It has two non-contact sheet-metal shields.
Why is there a slash in the designation 607/8-2Z?
The slash writes a bore that falls outside the two-digit code table: 607/8 means 8 mm bore. The site slug 607-8-ZZ replaces the slash with a hyphen.
How heavy is 607-8-ZZ?
Catalogue mass is 7.2 g for 607/8-2Z; seal and cage executions of the same envelope differ by a few grams.
What load can 607-8-ZZ take?
Catalogue values for 607/8-2Z: dynamic C 2.34 kN, static C0 0.95 kN, fatigue limit Pu 0.04 kN. Use C in life calculation and C0 for static checks at 8 mm bore.
