How the YAR-207-106-2RF-VE495 model number is decoded

The YAR2 series order number YAR 207-106-2RF/VE495 is a SKF insert bearing (Y-bearing) for a 34.925 mm (1.375 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 -106 decodes as 1" +6/16, i.e. 34.925 mm; the metric coded size YAR 207 shares the same envelope but its bore is the metric value, not this one. 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 34.925x72x42.9 mm (1.375x2.835x1.689 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. Bore-to-OD planning: OD 72 over bore 34.925 is a 2.062x step, while bore/overall-width gives 0.814; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. Imperial procurement cross-check: 1.375 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. At the printed limiting speed of 3,200 r/min the mean diameter dm = 53.462 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. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 34.925x72 mm insert on its chamfer tilts the whole spherical seat. 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. 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. Set-screw geometry on this size: the two 120 deg screws bear on the 34.925 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

• Do not specify the 34.925 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 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.
• Catalogue ratings belong to YAR 207-106-2RF/VE495 as the grub two ve495 execution; other order numbers of the YAR 207-106 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.
