How the 61914 model number is decoded

61914 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the thin 619xx section (diameter series 9 of ISO 15), multiplying bore code 14 by five gives the 70 mm bore; the 100 mm outside diameter and 16 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

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 61914 against the shaft shoulder while it cools so the ring cannot creep back.
• The 619xx thin section (15.0 mm section height at 70 mm bore) trades load capacity for compactness; stiff, accurately aligned seats are essential or edge loading will spall the raceway early.
• The open 61914 has no lubricant retention: grease escapes and contaminants migrate straight into the 70×100×16 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Open bearings tolerate the highest speeds in the 61900-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 61914 units.
• Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
• Deep-groove ball bearings tolerate only minutes of misalignment; if the 100 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 61914.
• The open 61914 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61914-2Z (shields) and 61914-2RSH (contact seals), not suffix-free 61914.
• The 23.8/18.3 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.
