How the YAR-210-115-2RFGR-HV model number is decoded

The YAR2 series order number YAR 210-115-2RFGR/HV is a SKF insert bearing (Y-bearing) for a 49.2125 mm (1.938 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 90 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 -115 decodes as 1" +15/16, i.e. 49.212 mm; the metric coded size YAR 210 shares the same envelope but its bore is the metric value, not this one. 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 49.2125x90x51.6 mm (1.938x3.543x2.031 in), outer ring 22 mm wide, C 29.6 kN, C0 23.2 kN, Pu 0.98 kN. The catalogue publishes a single speed ceiling, the limiting speed: 2,200 r/min; mass 790 g. Bore-to-OD planning: OD 90 over bore 49.2125 is a 1.829x step, while bore/overall-width gives 0.954; the spherical seat in the matching Y-housing must be specified to the 90 mm OD, not to a cylindrical housing bore. Rating split for the maintenance file: dynamic 29.6 kN (L10), static 23.2 kN (s0 shock check), fatigue 0.98 kN (adjusted life) — three separate uses for YAR 210-115-2RFGR/HV, none interchangeable with another. Spherical-seat note in numbers: the 90 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 69.606 = 218.674 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Mass-to-load ratio for YAR-210-115-2RFGR-HV: 26.689 g of catalogue mass per rated kN of C, and 16.053 g per millimetre of bore — useful when comparing executions of the same 49.2125x90 mm envelope on the drawing. Width accounting on this execution: 51.6 mm overall and 22 mm outer-ring width leave the housing designer 29.6 mm of inner-ring projection to accommodate the locking arrangement. 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-210-115-2RFGR-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 20.394 mm radial section.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Do not specify the 49.2125 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 32.6 mm s1 dimension is the screw seating geometry inside the 29.6 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• 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.
• Catalogue ratings belong to YAR 210-115-2RFGR/HV as the grub two hv execution; other order numbers of the YAR 210-115 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.
