How the 62302-2RS model number is decoded
The 62300-series is the wide-section counterpart of the standard deep-groove family (extra width code built into the designation); bore code 02 follows the 10/12/15/17 mm exception table, so 62302 fits a 15 mm shaft. The envelope is 15×42×17 mm (0.591×1.654×0.669 in) with a 13.5 mm radial section height, C 11.4 kN, C0 5.4 kN and Pu 0.228 kN. SKF catalogues the sealed execution as 62302-2RS1: 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 12000 r/min, catalogue mass 110 g.
Typical equipment & failure modes
Common applications
- agricultural equipment
- garden machinery
- textile machines
- electric 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
- brinelling from static overload or hammer blows during mounting
- false brinelling from vibration while the shaft stands idle
Selection pitfalls — read before you substitute
- At 15 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.
- Fillet radii must clear the 62302-2RS chamfer so the 17 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Contact seals make 62302-2RS slower than the open 62302 (limiting 12000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62302-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Do not preload 62302-2RS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Clearance suffixes follow the seal code in the designation stack (e.g. 62302-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of 62302-2RS?
The SKF 62302-2RS1 measures 15 mm bore × 42 mm OD × 17 mm width (0.591 × 1.654 × 0.669 in), mass about 110 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62302 work?
Codes 00–03 follow the exception table (10, 12, 15, 17 mm): 62302 fits a 15 mm shaft. Code × 5 starts at code 04.
How heavy is 62302-2RS?
Catalogue mass is 110 g for 62302-2RS1; seal and cage executions of the same envelope differ by a few grams.
What load can 62302-2RS take?
Catalogue values for 62302-2RS1: dynamic C 11.4 kN, static C0 5.4 kN, fatigue limit Pu 0.228 kN. Use C in life calculation and C0 for static checks at 15 mm bore.
