How the 607-2RS 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 catalogues the sealed execution as 607-2RSH: two contact elastomer lips (2RS1/2RSH spelling) over a lifetime grease fill; the lips add drag, and no reference (thermal) speed is published. Limiting speed 24000 r/min, catalogue mass 7.8 g.
Typical equipment & failure modes
Common applications
- model-making and hobby mechanics
- small pumps
- office equipment
- fractional-horsepower motors
Known failure patterns
- contact-seal lip hardening and pre-grease loss after long high-temperature service
- grease-life expiry inside the sealed-for-life cavity, which has 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
- Deep-groove geometry tolerates only minutes of misalignment; if the 19 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 607-2RS.
- Catalogue ratings for 607-2RS (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.
- Contact seals make 607-2RS slower than the open 607 (limiting 24000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 607-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Assign interference to the rotating ring: on a conventional shaft-mounted 7 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.
- Deep-groove geometry tolerates only minutes of misalignment; if the 19 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 607-2RS.
Frequently asked questions
What are the dimensions of 607-2RS?
The SKF 607-2RSH measures 7 mm bore × 19 mm OD × 6 mm width (0.276 × 0.748 × 0.236 in), mass about 7.8 g. It has two contact rubber seals and a lifetime grease fill.
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 607-2RS and a same-bore 62-series bearing?
Section height differs: 607-2RS 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 607-2RS?
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.
