How the YAR-207-107-2RF-HV model number is decoded

The YAR2 series order number YAR 207-107-2RF/HV is a SKF insert bearing (Y-bearing) for a 36.512499999999996 mm (1.438 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 72 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 -107 decodes as 1" +7/16, i.e. 36.512 mm; the metric coded size YAR 207 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; capacity is derated versus the carbon-steel part. Envelope 36.512499999999996x72x42.9 mm (1.438x2.835x1.689 in), outer ring 19 mm wide, C 21.6 kN, C0 15.3 kN, Pu 0.655 kN. The catalogue publishes a single speed ceiling, the limiting speed: 3,200 r/min; mass 420 g. Selection figures for YAR 207-107-2RF/HV: C0/C is 0.708, Pu 0.655 kN is 3.032 % of the 21.6 kN dynamic rating, and the 420 g catalogue mass works out to roughly 11.503 g per millimetre of the 36.512499999999996 mm bore. Outer-vs-overall width: the outer ring is 19 mm wide inside the 42.9 mm total, so the extended inner ring accounts for 0.557 of the overall width (11.95 mm of axial projection per side). Rating split for the maintenance file: dynamic 21.6 kN (L10), static 15.3 kN (s0 shock check), fatigue 0.655 kN (adjusted life) — three separate uses for YAR 207-107-2RF/HV, none interchangeable with another. Load balance for documentation: C0 15.3 kN against C 21.6 kN gives a 0.708 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. Speed ceiling of 3,200 r/min is the catalogue mechanical limit for THIS execution; the stainless/food-grade HV fill sets this lower value, so real fan duty is planned well below it. 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 36.512499999999996 mm shaft inside the 42.9 mm total width while the outer ring is only 19 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.
• The 25.4 mm s1 dimension is the screw seating geometry inside the 23.9 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• Do not specify the 36.512499999999996 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.
• Ordering discipline for the 36.512499999999996 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.
