How the 62313-2RS 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); the last two digits encode the bore: 62313 carries code 13 = 65 mm (code × 5). The envelope is 65×140×48 mm (2.559×5.512×1.89 in) with a 37.5 mm radial section height, C 92.3 kN, C0 60 kN and Pu 2.5 kN. SKF catalogues the sealed execution as 62313-2RS1: 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 3200 r/min, catalogue mass 3000 g.
Typical equipment & failure modes
Common applications
- agricultural gearboxes
- industrial electric motors
- gearboxes and speed reducers
- centrifugal and positive-displacement pumps
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
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- Assign interference to the rotating ring: on a conventional shaft-mounted 65 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.
- Fillet radii must clear the 62313-2RS chamfer so the 48 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Contact seals make 62313-2RS slower than the open 62313 (limiting 3200 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62313-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Do not preload 62313-2RS 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. 62313-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of 62313-2RS?
The SKF 62313-2RS1 measures 65 mm bore × 140 mm OD × 48 mm width (2.559 × 5.512 × 1.89 in), mass about 3000 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62313 work?
The final two digits of 62313 are bore code 13, multiplied by 5 to give 65 mm.
What is the difference between 62313-2RS and a same-bore 62-series bearing?
Section height differs: 62313-2RS has a 37.5 mm radial section and C 92.3 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 62313-2RS?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 140 mm housing; reverse the interference if the outer ring rotates.
