How the YAR-214-207-2F model number is decoded

Listed in SKF 17000 chapter 2, YAR 214-207-2F is a grub-screw insert bearing with the inner ring extended on both sides, 61.912499999999994x125x69.9 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction follows the Y-bearing principle: a capped and flinger-protected deep-groove ball insert, inner ring elongated for the screw points, outer ring convex-spherical for the housing seat. YAR is SKF's grub-screw insert design — an inner ring extended equally past the outer ring on both sides, the screws still 120 deg apart. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -207 = 61.912 mm, which is why this row sits beside, not on, the metric bore size. -2F decodes to contact seals with additional plain flingers, one set per side; the unit is grease-filled for life and the flinger is why the sealed width exceeds the open one-side execution. Envelope 61.912499999999994x125x69.9 mm (2.438x4.921x2.752 in), outer ring 28 mm wide, C 62.4 kN, C0 45 kN, Pu 1.86 kN. The catalogue publishes a single speed ceiling, the limiting speed: 2,800 r/min; mass 2400 g. Selection figures for YAR 214-207-2F: C0/C is 0.721, Pu 1.86 kN is 2.981 % of the 62.4 kN dynamic rating, and the 2400 g catalogue mass works out to roughly 38.764 g per millimetre of the 61.912499999999994 mm bore. At the printed limiting speed of 2,800 r/min the mean diameter dm = 93.456 mm implies dn about 2.62x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Outer-vs-overall width: the outer ring is 28 mm wide inside the 69.9 mm total, so the extended inner ring accounts for 0.599 of the overall width (20.95 mm of axial projection per side). Load balance for documentation: C0 45 kN against C 62.4 kN gives a 0.721 ratio; mounted-unit positions with shock and standstill loading are normally checked on C0, while conveyor and fan duty are evaluated on the L10 figure. Rating split for the maintenance file: dynamic 62.4 kN (L10), static 45 kN (s0 shock check), fatigue 1.86 kN (adjusted life) — three separate uses for YAR 214-207-2F, none interchangeable with another. Both-sides sealed order-number note: the two set screws clamp through dimpled recesses in the extended inner ring; tighten alternately to the catalogue procedure and retighten after the first run-in period, because the -2F flingers keep dust out but cannot compensate for a screw that walked loose. Set-screw geometry on this size: the two 120 deg screws bear on the 61.912499999999994 mm shaft inside the 69.9 mm total width while the outer ring is only 28 mm wide, leaving the extended ring to carry the screw points clear of the ball track.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Replacement discipline: a YAR insert is not interchangeable with an eccentric-collar unit of the same envelope — the shaft may need spot-facing or collar space that does not exist.
• Do not specify the 61.912499999999994 mm grub-screw insert for a shaft harder than about 45 HRC without dimples: the screw points skate on hard surfaces and the unit creeps regardless of tightening torque.
• The 39.7 mm s1 dimension is the screw seating geometry inside the 41.9 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• Ordering discipline for the 61.912499999999994 mm size: the chapter lists several executions side by side (YAR2 locking style x seal package x application variant); a bare-number substitution needs a fresh dimension, speed and rating check rather than a like-for-like assumption.
