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

Listed in SKF 17000 chapter 2, YAR 210-2RF/VE495 is a grub-screw insert bearing with the inner ring extended on both sides, 50x90x51.6 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. the size code 210 carries the usual bore arithmetic — 50 mm (code 10 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. VE495 denotes galvanized rings plus food-compatible sealing components and grease, aimed at humid, cleaned-down installations rather than submerged chemical duty. Envelope 50x90x51.6 mm (1.969x3.543x2.031 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 770 g. Width accounting on this execution: 51.6 mm overall and 22 mm outer-ring width leave the housing designer 29.6 mm of inner-ring projection to accommodate the locking arrangement. Imperial procurement cross-check: 1.969 in bore, 3.543 in OD, 2.031 in overall width; the 770 g mass converts to 0.770 kg (27.2 oz) for the bill of materials. Load balance for documentation: C0 23.2 kN against C 35.1 kN gives a 0.661 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. Static-first planning: the 0.45 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 50 mm shaft, not the 35.1 kN L10 value. Grease-life arithmetic is dominated by speed: at dn approx 1.54x10^5 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. 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-210-2RF-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 20 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.
• 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.
• Do not specify the 50 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.
• Ordering discipline for the 50 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.
