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

The YAR2 series order number YAR 213-2F is a SKF insert bearing (Y-bearing) for a 65 mm 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. the size code 213 carries the usual bore arithmetic — 65 mm (code 13 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. 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 65x120x68.3 mm (2.559x4.724x2.689 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 1800 g. Envelope arithmetic: the radial section from 65 mm bore to 120 mm OD is 27.5 mm; dividing C 57.2 kN by that section gives 2.08 kN per section millimetre, and the 68.3 mm overall width is 2.484x the section. Mass-to-load ratio for YAR-213-2F: 31.469 g of catalogue mass per rated kN of C, and 27.692 g per millimetre of bore — useful when comparing executions of the same 65x120 mm envelope on the drawing. 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 65 mm shaft, not the 57.2 kN L10 value. Grease-life arithmetic is dominated by speed: at dn approx 2.77x10^5 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. 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. Set-screw geometry on this size: the two 120 deg screws bear on the 65 mm shaft inside the 68.3 mm total width while the outer ring is only 27 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

• 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.
• 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 65 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 57.2/40 kN figures belong specifically to YAR 213-2F; 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.
