How the 6014 model number is decoded
6014 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 14 by five gives the 70 mm bore; the 110 mm outside diameter and 20 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 70 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
- brinelling from static overload or hammering during mounting
- false brinelling from vibration while the shaft is stationary
Selection pitfalls — read before you substitute
- At 70 mm bore, induction heating to roughly 80–100 °C is the clean mounting method; never exceed 120 °C, and hold 6014 against the shaft shoulder while it cools so the ring cannot creep back.
- Choosing the 60xx extra-light section saves radial space at 70 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6214 before committing to the smaller envelope.
- The open 6014 has no lubricant retention: grease escapes and contaminants migrate straight into the 70×110×20 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6014 units.
- Measure the shaft, do not trust the drawing: a 70 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6014.
- The housing bore for the 110 mm OD should be round within IT7; an oval bore pinches the outer ring of 6014 and shows up later as two-point loaded raceway wear.
- The open 6014 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6014-2Z (shields) and 6014-2RSH (contact seals), not suffix-free 6014.
- The 39.7/31 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 6014 bearing?
A 6014 deep-groove ball bearing has a 70 mm bore, 110 mm outer diameter and 20 mm width (2.756 × 4.331 × 0.787 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What lubrication does 6014 need?
The open 6014 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
How does the 6014 bore code work?
The last two digits of 6014 are bore code 14, giving 14 × 5 = 70 mm bore. The 110 mm outside diameter and 20 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 6014 mean?
A bare 6014 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.
What is the SKF designation and catalogue data for 6014?
In the SKF Rolling Bearings catalogue this size is listed as 6014 — the open (unsealed) execution, 70×110×20 mm per ISO 15. Quoted values: C 39.7 kN, C0 31 kN, Pu 1.32 kN, limiting speed 8000 r/min, mass 610 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6014.
