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

Listed in SKF 17000 chapter 2, YAR 206-103-2RFGR/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. Grease-life arithmetic is dominated by speed: at dn approx 1.75x10^5 the sealed-for-life fill is planned for the catalogue's grease-life regime, which is why the limiting speed and the relubrication interval move together, and high-temperature mounts shorten both even when load is light. Rating split for the maintenance file: dynamic 16.3 kN (L10), static 11.2 kN (s0 shock check), fatigue 0.475 kN (adjusted life) — three separate uses for YAR 206-103-2RFGR/HV, none interchangeable with another. Static-first planning: the 0.294 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 30.162499999999998 mm shaft, not the 16.3 kN L10 value. At the printed limiting speed of 3,800 r/min the mean diameter dm = 46.081 mm implies dn about 1.75x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Pitch-diameter arithmetic: dm = (30.162499999999998+62)/2 = 46.081 mm; at the 3,800 r/min limiting speed the ball set runs at dn approx 1.75x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. 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. Set-screw geometry on this size: the two 120 deg screws bear on the 30.162499999999998 mm shaft inside the 38.1 mm total width while the outer ring is only 18 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

• 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.
• 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.
• 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.
• The 16.3/11.2 kN figures belong specifically to YAR 206-103-2RFGR/HV; HV stainless, AG agricultural and VE495 zinc-plated variants of the same envelope publish derated values, so write the complete order number including suffixes on the purchase and maintenance records.
