How the 6213 model number is decoded
6213 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 13 by five gives the 65 mm bore; the 120 mm outside diameter and 23 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 65 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- material-handling equipment
- industrial fans
- industrial electric motors
- centrifugal and positive-displacement pumps
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- brinelling from static overload or hammering during mounting
- false brinelling from vibration while the shaft is stationary
Selection pitfalls — read before you substitute
- Interference on a 65 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6213 with C3 clearance and re-check the residual value after mounting.
- The 62xx light series is the default general-purpose section at 65 mm bore; before upgrading to a 6313 for extra capacity, confirm the housing accepts a 120 mm OD and 23 mm width — it is not a drop-in swap.
- The open 6213 has no lubricant retention: grease escapes and contaminants migrate straight into the 65×120×23 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6213 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- Measure the shaft, do not trust the drawing: a 65 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6213.
- Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 23 mm-wide ring of 6213 drags the lip and overheats it.
- The open 6213 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6213-2Z (shields) and 6213-2RSH (contact seals), not suffix-free 6213.
- The 58.5/40.5 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6213 bearing?
A 6213 deep-groove ball bearing has a 65 mm bore, 120 mm outer diameter and 23 mm width (2.559 × 4.724 × 0.906 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How does the 6200 compare with other series at the same 65 mm bore?
The '2' is the light diameter series: 120×23 mm with a 27.5 mm radial section at 65 mm bore. A 6313 on the same bore is larger and higher-rated; a 6013 is smaller and lower-rated.
Are 6213 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6213 uses the same ISO 15 envelope (65×120×23 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What internal clearance does 6213 have?
Unless a clearance suffix says otherwise, 6213 is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6213 and verify the residual clearance after mounting.
What is the SKF designation and catalogue data for 6213?
In the SKF Rolling Bearings catalogue this size is listed as 6213 — the open (unsealed) execution, 65×120×23 mm per ISO 15. Quoted values: C 58.5 kN, C0 40.5 kN, Pu 1.73 kN, limiting speed 7500 r/min, mass 1000 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6213.
