How the 607-ZZ model number is decoded
In the 6000-series, the final digit is the bore in millimetres: 607 fits a 7 mm shaft (direct-number miniature spelling). The envelope is 7×19×6 mm (0.276×0.748×0.236 in) with a 6.0 mm radial section height, C 2.34 kN, C0 0.95 kN and Pu 0.04 kN. SKF spells the double shield 607-2Z (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 8.4 g.
Typical equipment & failure modes
Common applications
- instrument and encoder drives
- model-making and hobby mechanics
- small pumps
- office equipment
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
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
- brinelling from static overload or hammer blows during mounting
Selection pitfalls — read before you substitute
- Fillet radii must clear the 607-ZZ chamfer so the 6 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- At 7 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.
- Shields on 607-ZZ are non-contact: chips and coarse dust stay out, but water passes straight through — specify the sealed 607-2RS for washdown duty.
- Do not pry the caps off 607-ZZ to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Catalogue ratings for 607-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.
- Mount by heating the inner ring (max 120 °C) — driving 607-ZZ home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of 607-ZZ?
The SKF 607-2Z measures 7 mm bore × 19 mm OD × 6 mm width (0.276 × 0.748 × 0.236 in), mass about 8.4 g. It has two non-contact sheet-metal shields.
How do I read the 607 designation?
Small miniature bearings print the bore as the final digit, so 607 is a 7 mm bearing; the series digits in front give the section (OD/width family).
What is the difference between 607-ZZ and a same-bore 62-series bearing?
Section height differs: 607-ZZ has a 6 mm radial section and C 2.34 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 607-ZZ?
With a rotating inner ring use roughly j5/k5 on the shaft and H7 in the 19 mm housing; reverse the interference if the outer ring rotates.
