How the YAR-207-2RF-VE495 model number is decoded

The YAR2 series order number YAR 207-2RF/VE495 is a SKF insert bearing (Y-bearing) for a 35 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 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. the size code 207 carries the usual bore arithmetic — 35 mm (code 07 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. the VE495 suffix packages zinc-coated rings with stainless-reinforced food-grade seals/flingers and food-grade lubricant — the wash-down-resistant counterpart of the standard -2RF bearing. Envelope 35x72x42.9 mm (1.378x2.835x1.689 in), outer ring 19 mm wide, C 25.5 kN, C0 15.3 kN, Pu 0.655 kN. The catalogue publishes a single speed ceiling, the limiting speed: 3,200 r/min; mass 450 g. Capacity density: 25.5 kN from 0.450 kg of bearing steel is about 56.667 kN per kilogram, and per width millimetre the 42.9 mm unit carries 0.594 kN of dynamic capacity. Load balance for documentation: C0 15.3 kN against C 25.5 kN gives a 0.6 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. Imperial procurement cross-check: 1.378 in bore, 2.835 in OD, 1.689 in overall width; the 450 g mass converts to 0.450 kg (15.9 oz) for the bill of materials. The s1 25.4 mm dimension is printed for the locking zone — the set-screw/collar seating reference — and it is verified at mounting, not recoverable from d/D/B alone. At the printed limiting speed of 3,200 r/min the mean diameter dm = 53.5 mm implies dn about 1.71x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Zinc-coated food-range note: the VE495 plating is a functional surface, not cosmetic; clean the bore and shaft WITHOUT steel brushes or aggressive descalers, mount dry or with the approved food-grade mounting paste, and touch up damaged plating spots before commissioning the wash-down area. Service tip for YAR-207-2RF-VE495: 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 18.5 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 35 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 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.
• Ordering discipline for the 35 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.
