How the YAR-210-115-2RF-VE495 model number is decoded

YAR 210-115-2RF/VE495 is SKF's 49.2125 mm-bore grub-screw insert bearing with the inner ring extended on both sides in the YAR2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 49.2125x90x51.6 mm. Wide-inner-ring deep-groove ball geometry carries the load: the extended inner ring gives the shaft grip and the seal lands, while the outer ring stays narrow and spherically ground on its outside surface. the YAR prefix names SKF grub-screw Y-bearings: two set screws in the extended inner ring lock the shaft at a 120 deg angle, and the inner ring extends symmetrically on both sides. the three-digit -115 tail codes the bore in inches for inch-shaft bearings: 1 whole inch 15/16 in = 49.212 mm (first digit whole inches, next two sixteenths of an inch). /VE495 is the zinc-plated food-industry execution: zinc-coated inner and outer rings, seals and flingers with stainless-steel inserts in food-compatible rubber, and food-grade grease fill. Envelope 49.2125x90x51.6 mm (1.938x3.543x2.031 in), outer ring 22 mm wide, C 35.1 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. Mass-to-load ratio for YAR-210-115-2RF-VE495: 22.507 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. Imperial procurement cross-check: 1.938 in bore, 3.543 in OD, 2.031 in overall width; the 790 g mass converts to 0.790 kg (27.9 oz) for the bill of materials. At the printed limiting speed of 2,200 r/min the mean diameter dm = 69.606 mm implies dn about 1.53x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. 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. Speed ceiling of 2,200 r/min is the catalogue mechanical limit for THIS execution; seal lip and flinger drag, not steel fatigue, are normally what cap it, so real fan duty is planned well below it. 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 49.2125 mm shaft inside the 51.6 mm total width while the outer ring is only 22 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 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.
• 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 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.
• Catalogue ratings belong to YAR 210-115-2RF/VE495 as the grub two ve495 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.
