How the YAR-206-103-2RF-HV model number is decoded

Listed in SKF 17000 chapter 2, YAR 206-103-2RF/HV is a grub-screw insert bearing with the inner ring extended on both sides, 30.162499999999998x62x38.1 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: -103 = 30.162 mm, which is why this row sits beside, not on, the metric bore size. HV is the corrosion-resistant food-range variant of the -2RF sealed design — stainless parts plus food-compatible rubber and lubricant, which also explains its lower published C and limiting speed. Envelope 30.162499999999998x62x38.1 mm (1.188x2.441x1.5 in), outer ring 18 mm wide, C 16.3 kN, C0 11.2 kN, Pu 0.475 kN. The catalogue publishes a single speed ceiling, the limiting speed: 3,800 r/min; mass 300 g. Outer-vs-overall width: the outer ring is 18 mm wide inside the 38.1 mm total, so the extended inner ring accounts for 0.528 of the overall width (10.05 mm of axial projection per side). Mass-to-load ratio for YAR-206-103-2RF-HV: 18.405 g of catalogue mass per rated kN of C, and 9.946 g per millimetre of bore — useful when comparing executions of the same 30.162499999999998x62 mm envelope on the drawing. Fillet discipline: the printed r_min 0.6 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 30.162499999999998x62 mm insert on its chamfer tilts the whole spherical seat. Spherical-seat note in numbers: the 62 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 46.081 = 144.768 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Envelope arithmetic: the radial section from 30.162499999999998 mm bore to 62 mm OD is 15.919 mm; dividing C 16.3 kN by that section gives 1.024 kN per section millimetre, and the 38.1 mm overall width is 2.393x the section. Stainless food-range note: HV parts trade some capacity for corrosion resistance and food-compatible lubrication, and the printed limiting speed is set for that fill; do not top up with ordinary mineral grease in service — mixing greases can harden the food-grade fill and seize the seals. Service tip for YAR-206-103-2RF-HV: dimpled or drilled shaft spots under the screw points are sometimes specified on shock duty, but the standard mounting relies on point indentation alone — never substitute longer screws that reach the 15.919 mm radial section.

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 30.162499999999998 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 22.2 mm s1 dimension is the screw seating geometry inside the 20.1 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• Ordering discipline for the 30.162499999999998 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.
