How the YAR-213-211-2F model number is decoded

The YAR2 series order number YAR 213-211-2F is a SKF insert bearing (Y-bearing) for a 68.2625 mm (2.688 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 120 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 -211 decodes as 2" +11/16, i.e. 68.263 mm; the metric coded size YAR 213 shares the same envelope but its bore is the metric value, not this one. the -2F external design pairs a nitrile contact seal with a plain sheet-steel thrower on both sides — a two-stage exclusion chain of flinger first, sealing lip second, typical of farm and conveyor duty. Envelope 68.2625x120x68.3 mm (2.688x4.724x2.689 in), outer ring 27 mm wide, C 57.2 kN, C0 40 kN, Pu 1.7 kN. The catalogue publishes a single speed ceiling, the limiting speed: 3,000 r/min; mass 1600 g. Imperial procurement cross-check: 2.688 in bore, 4.724 in OD, 2.689 in overall width; the 1600 g mass converts to 1.600 kg (56.4 oz) for the bill of materials. Width accounting on this execution: 68.3 mm overall and 27 mm outer-ring width leave the housing designer 41.3 mm of inner-ring projection to accommodate the locking arrangement. Static-first planning: the 0.586 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 68.2625 mm shaft, not the 57.2 kN L10 value. Mass-to-load ratio for YAR-213-211-2F: 27.972 g of catalogue mass per rated kN of C, and 23.439 g per millimetre of bore — useful when comparing executions of the same 68.2625x120 mm envelope on the drawing. Rating split for the maintenance file: dynamic 57.2 kN (L10), static 40 kN (s0 shock check), fatigue 1.7 kN (adjusted life) — three separate uses for YAR 213-211-2F, none interchangeable with another. Both-sides sealed order-number note: the two set screws clamp through dimpled recesses in the extended inner ring; tighten alternately to the catalogue procedure and retighten after the first run-in period, because the -2F flingers keep dust out but cannot compensate for a screw that walked loose. Service tip for YAR-213-211-2F: 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 25.869 mm radial section.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The 42.9 mm s1 dimension is the screw seating geometry inside the 41.3 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• Do not specify the 68.2625 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 57.2/40 kN figures belong specifically to YAR 213-211-2F; 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.
