How the 6214 model number is decoded
In the 6200-series (diameter series 2 of ISO 15) the last two digits encode the bore: 6214 carries bore code 14 = 70 mm. Outside diameter 125 mm and width 24 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 70 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. 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
- industrial fans
- industrial electric motors
- centrifugal and positive-displacement pumps
- gearboxes and speed reducers
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- Interference on a 70 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6214 with C3 clearance and re-check the residual value after mounting.
- The 62xx light series is the default general-purpose section at 70 mm bore; before upgrading to a 6314 for extra capacity, confirm the housing accepts a 125 mm OD and 24 mm width — it is not a drop-in swap.
- The open 6214 has no lubricant retention: grease escapes and contaminants migrate straight into the 70×125×24 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6214 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 70 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6214.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 125 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6214.
- The open 6214 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6214-2Z (shields) and 6214-2RSH (contact seals), not suffix-free 6214.
- The 63.7/45 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 6214 bearing?
A 6214 deep-groove ball bearing has a 70 mm bore, 125 mm outer diameter and 24 mm width (2.756 × 4.921 × 0.945 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What internal clearance does 6214 have?
Unless a clearance suffix says otherwise, 6214 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 6214 and verify the residual clearance after mounting.
How should 6214 be mounted?
Apply the mounting force to the ring being fitted: on a 70 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 6214 need?
The open 6214 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.
What is the SKF designation and catalogue data for 6214?
In the SKF Rolling Bearings catalogue this size is listed as 6214 — the open (unsealed) execution, 70×125×24 mm per ISO 15. Quoted values: C 63.7 kN, C0 45 kN, Pu 1.9 kN, limiting speed 7000 r/min, mass 1100 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6214.
