How the YARAG-209-110 model number is decoded

The YAR2 series order number YARAG 209-110 is a SKF insert bearing (Y-bearing) for a 41.275 mm (1.625 in) shaft: grub-screw insert bearing with the inner ring extended on both sides, built to the ISO 15 diameter-series envelope with a sphered OD of 85 mm. Inside is a sealed deep-groove ball set with an extended inner ring, two set screws 120 deg apart doing the shaft locking, and the sphered outer ring providing the unit's static alignment pivot. reading the YAR basic designation: set-screw shaft locking with the screws spaced 120 deg apart; YAR carries the symmetric, both-sides-extended inner ring. inch bore code -110 decodes as 1" +10/16, i.e. 41.275 mm; the metric coded size YARAG 209 shares the same envelope but its bore is the metric value, not this one. the AG suffix identifies the farm-duty variant of the range: sealed and flinger-protected for chaff and dust, with the catalogue deliberately derating its permissible speed versus the industrial execution. Envelope 41.275x85x49.2 mm (1.625x3.346x1.937 in), outer ring 22 mm wide, C 33.2 kN, C0 21.6 kN, Pu 0.915 kN. The catalogue publishes a single speed ceiling, the limiting speed: 850 r/min; mass 750 g. At the printed limiting speed of 850 r/min the mean diameter dm = 63.138 mm implies dn about 0.54x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 56.8 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the inner flinger. Rating split for the maintenance file: dynamic 33.2 kN (L10), static 21.6 kN (s0 shock check), fatigue 0.915 kN (adjusted life) — three separate uses for YARAG 209-110, none interchangeable with another. Imperial procurement cross-check: 1.625 in bore, 3.346 in OD, 1.937 in overall width; the 750 g mass converts to 0.750 kg (26.5 oz) for the bill of materials. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 41.275x85 mm insert on its chamfer tilts the whole spherical seat. Set-screw geometry on this size: the two 120 deg screws bear on the 41.275 mm shaft inside the 49.2 mm total width while the outer ring is only 22 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 41.275 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 30.2 mm s1 dimension is the screw seating geometry inside the 27.2 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• Ordering discipline for the 41.275 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.
