How the YAR-207-107-2RF-VE495 model number is decoded

Listed in SKF 17000 chapter 2, YAR 207-107-2RF/VE495 is a grub-screw insert bearing with the inner ring extended on both sides, 36.512499999999996x72x42.9 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction follows the Y-bearing principle: a capped and flinger-protected deep-groove ball insert, inner ring elongated for the screw points, outer ring convex-spherical for the housing seat. YAR is SKF's grub-screw insert design — an inner ring extended equally past the outer ring on both sides, the screws still 120 deg apart. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -107 = 36.512 mm, which is why this row sits beside, not on, the metric bore size. VE495 denotes galvanized rings plus food-compatible sealing components and grease, aimed at humid, cleaned-down installations rather than submerged chemical duty. Envelope 36.512499999999996x72x42.9 mm (1.438x2.835x1.689 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 420 g. Bore-to-OD planning: OD 72 over bore 36.512499999999996 is a 1.972x step, while bore/overall-width gives 0.851; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. Grease-life arithmetic is dominated by speed: at dn approx 1.74x10^5 the sealed-for-life fill is planned for the catalogue's grease-life regime, which is why the limiting speed and the relubrication interval move together, and high-temperature mounts shorten both even when load is light. Spherical-seat note in numbers: the 72 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 54.256 = 170.45 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Capacity density: 25.5 kN from 0.420 kg of bearing steel is about 60.714 kN per kilogram, and per width millimetre the 42.9 mm unit carries 0.594 kN of dynamic capacity. Static-first planning: the 0.357 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 36.512499999999996 mm shaft, not the 25.5 kN L10 value. 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-207-107-2RF-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 17.744 mm radial section.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• 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.
• 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.
• Catalogue ratings belong to YAR 207-107-2RF/VE495 as the grub two ve495 execution; other order numbers of the YAR 207-107 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.
