How the YARAG-210-115 model number is decoded

Listed in SKF 17000 chapter 2, YARAG 210-115 is a grub-screw insert bearing with the inner ring extended on both sides, 49.2125x90x51.6 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. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -115 = 49.212 mm, which is why this row sits beside, not on, the metric bore size. AG is the application variant for agricultural equipment — the same bore and OD as the standard sealed size but an application-specific grease/seal build and a conservative limiting speed for field machinery. Envelope 49.2125x90x51.6 mm (1.938x3.543x2.031 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: 800 r/min; mass 770 g. Rating split for the maintenance file: dynamic 35.1 kN (L10), static 23.2 kN (s0 shock check), fatigue 0.98 kN (adjusted life) — three separate uses for YARAG 210-115, none interchangeable with another. The s1 32.6 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. Bore-to-OD planning: OD 90 over bore 49.2125 is a 1.829x step, while bore/overall-width gives 0.954; the spherical seat in the matching Y-housing must be specified to the 90 mm OD, not to a cylindrical housing bore. 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 49.2125 mm shaft, not the 35.1 kN L10 value. Spherical-seat note in numbers: the 90 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 69.606 = 218.674 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Service tip for YARAG-210-115: 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 20.394 mm radial section.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• 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 49.2125 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 35.1/23.2 kN figures belong specifically to YARAG 210-115; 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.
