How the 63001-2RS 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); bore code 01 follows the 10/12/15/17 mm exception table, so 63001 fits a 12 mm shaft. The envelope is 12×28×12 mm (0.472×1.102×0.472 in) with a 8.0 mm radial section height, C 5.07 kN, C0 2.36 kN and Pu 0.1 kN. SKF catalogues the sealed execution as 63001-2RS1: 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 17000 r/min, catalogue mass 29 g.
Typical equipment & failure modes
Common applications
- fans and blowers
- agricultural equipment
- garden machinery
- textile machines
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
- false brinelling from vibration while the shaft stands idle
- fretting corrosion on a creeping shaft or housing seat
Selection pitfalls — read before you substitute
- Mount by heating the inner ring (max 120 °C) — driving 63001-2RS home through the outer ring or balls brinells the raceways.
- Deep-groove geometry tolerates only minutes of misalignment; if the 28 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 63001-2RS.
- Contact seals make 63001-2RS slower than the open 63001 (limiting 17000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 63001-2RS 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 28 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 63001-2RS.
- Do not preload 63001-2RS 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 63001-2RS?
The SKF 63001-2RS1 measures 12 mm bore × 28 mm OD × 12 mm width (0.472 × 1.102 × 0.472 in), mass about 29 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 63001 work?
Codes 00–03 follow the exception table (10, 12, 15, 17 mm): 63001 fits a 12 mm shaft. Code × 5 starts at code 04.
What is the speed rating of 63001-2RS?
SKF publishes only the 17000 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 63001-2RS and a same-bore 62-series bearing?
Section height differs: 63001-2RS has a 8 mm radial section and C 5.07 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
