How the 6413 model number is decoded
6413 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the heavy 64xx section (diameter series 4 of ISO 15), multiplying bore code 13 by five gives the 65 mm bore; the 160 mm outside diameter and 37 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
- gearboxes and speed reducers
- conveyor drives
- material-handling equipment
- industrial fans
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- At 65 mm bore, induction heating to roughly 80–100 °C is the clean mounting method; never exceed 120 °C, and hold 6413 against the shaft shoulder while it cools so the ring cannot creep back.
- The 64xx heavy section at 65 mm bore (160 mm OD) is built for high-load, lower-speed duty; specifying it in a high-rpm motor gives excess heat and short grease life — use 62/63 there.
- The open 6413 has no lubricant retention: grease escapes and contaminants migrate straight into the 65×160×37 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6413 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.
- Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 37 mm-wide ring of 6413 drags the lip and overheats it.
- Do not quieten a noisy bearing by preloading it: the 6400-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
- The open 6413 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6413-2Z (shields) and 6413-2RSH (contact seals), not suffix-free 6413.
- The 119/78 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 6413 bearing?
A 6413 deep-groove ball bearing has a 65 mm bore, 160 mm outer diameter and 37 mm width (2.559 × 6.299 × 1.457 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What does no suffix on 6413 mean?
A bare 6413 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 6400 compare with other series at the same 65 mm bore?
The '4' is the heavy diameter series: 160×37 mm, 47.5 mm radial section at 65 mm bore — the highest-capacity single-row 6xx option here, aimed at lower-speed, high-load shafts.
Are 6413 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6413 uses the same ISO 15 envelope (65×160×37 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What is the SKF designation and catalogue data for 6413?
In the SKF Rolling Bearings catalogue this size is listed as 6413 — the open (unsealed) execution, 65×160×37 mm per ISO 15. Quoted values: C 119 kN, C0 78 kN, Pu 3.15 kN, limiting speed 6000 r/min, mass 3350 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6413.
