How the 63007-2RS model number is decoded
The 63000-series is the wide-section counterpart of the standard deep-groove family (extra width code built into the designation); the last two digits encode the bore: 63007 carries code 07 = 35 mm (code × 5). The envelope is 35×62×20 mm (1.378×2.441×0.787 in) with a 13.5 mm radial section height, C 15.9 kN, C0 10.2 kN and Pu 0.44 kN. SKF catalogues the sealed execution as 63007-2RS1: 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 7000 r/min, catalogue mass 220 g.
Typical equipment & failure modes
Common applications
- centrifugal and positive-displacement pumps
- material-handling equipment
- industrial fans
- compressor drives
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
- 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
- The fatigue load limit is 0.44 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- Clearance suffixes follow the seal code in the designation stack (e.g. 63007-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- Contact seals make 63007-2RS slower than the open 63007 (limiting 7000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 63007-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Deep-groove geometry tolerates only minutes of misalignment; if the 62 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 63007-2RS.
- Do not preload 63007-2RS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
Frequently asked questions
What are the dimensions of 63007-2RS?
The SKF 63007-2RS1 measures 35 mm bore × 62 mm OD × 20 mm width (1.378 × 2.441 × 0.787 in), mass about 220 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 63007 work?
The final two digits of 63007 are bore code 07, multiplied by 5 to give 35 mm.
What is the speed rating of 63007-2RS?
SKF publishes only the 7000 r/min limiting speed for this execution; sealed variants have no thermal reference speed because seal and grease life govern.
What is the difference between 63007-2RS and a same-bore 62-series bearing?
Section height differs: 63007-2RS has a 13.5 mm radial section and C 15.9 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
