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

The YAR2 series order number YAR 206-2RFGR/HV is a SKF insert bearing (Y-bearing) for a 30 mm 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 62 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. the size code 206 carries the usual bore arithmetic — 30 mm (code 06 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. the HV suffix means stainless rings and balls with food-grade compliant seals and grease (this article also carries the GR outside-surface lubrication groove); capacity is derated versus the carbon-steel part. Envelope 30x62x38.1 mm (1.181x2.441x1.5 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. Capacity density: 16.3 kN from 0.300 kg of bearing steel is about 54.333 kN per kilogram, and per width millimetre the 38.1 mm unit carries 0.428 kN of dynamic capacity. Imperial procurement cross-check: 1.181 in bore, 2.441 in OD, 1.5 in overall width; the 300 g mass converts to 0.300 kg (10.6 oz) for the bill of materials. Load balance for documentation: C0 11.2 kN against C 16.3 kN gives a 0.687 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. 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 = 144.513 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Fatigue-limit check: Pu 0.475 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YAR 206-2RFGR/HV — most belt-driven mounted-unit loads sit comfortably under 2.914 % of C. 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-206-2RFGR-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 16 mm radial section.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Do not specify the 30 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 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.
• Catalogue ratings belong to YAR 206-2RFGR/HV as the grub two hv execution; other order numbers of the YAR 206 size are different articles (open vs sealed, plain vs rubberized flinger, stainless vs carbon steel) and may carry different ratings or speeds — always quote the full designation.
