How the YAR-206-103-2RF-VE495 model number is decoded

YAR 206-103-2RF/VE495 is SKF's 30.162499999999998 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 30.162499999999998x62x38.1 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 -103 tail codes the bore in inches for inch-shaft bearings: 1 whole inch 3/16 in = 30.162 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 30.162499999999998x62x38.1 mm (1.188x2.441x1.5 in), outer ring 18 mm wide, C 19.5 kN, C0 11.2 kN, Pu 0.475 kN. The catalogue publishes a single speed ceiling, the limiting speed: 3,800 r/min; mass 300 g. Width accounting on this execution: 38.1 mm overall and 18 mm outer-ring width leave the housing designer 20.1 mm of inner-ring projection to accommodate the locking arrangement. Imperial procurement cross-check: 1.188 in bore, 2.441 in OD, 1.5 in overall width; the 300 g mass converts to 0.300 kg (10.6 oz) for the bill of materials. The s1 22.2 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. Spherical-seat note in numbers: the 62 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 46.081 = 144.768 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 39.7 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the inner flinger. 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-206-103-2RF-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 15.919 mm radial section.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The 22.2 mm s1 dimension is the screw seating geometry inside the 20.1 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.
• Do not specify the 30.162499999999998 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 19.5/11.2 kN figures belong specifically to YAR 206-103-2RF/VE495; HV stainless, AG agricultural and VE495 zinc-plated variants of the same envelope publish derated values, so write the complete order number including suffixes on the purchase and maintenance records.
