How the YSPAG-210-115 model number is decoded

The YSP2 series order number YSPAG 210-115 is a SKF insert bearing (Y-bearing) for a 49.2125 mm (1.938 in) shaft: SKF ConCentra insert bearing with concentric stepped-sleeve locking and symmetrically extended inner ring, built to the ISO 15 diameter-series envelope with a sphered OD of 90 mm. Inside is a capped ball insert whose extended inner ring tapers onto a multi-step locking sleeve; the sleeve grips the shaft around its full circumference and the spherical outer ring pivots in the housing. YSP denotes the ConCentra design — the SB execution in this chapter has the shortened inner ring; axial driving of the stepped sleeve produces a near-true concentric clamp with virtually no run-out penalty. inch bore code -115 decodes as 1" +15/16, i.e. 49.212 mm; the metric coded size YSPAG 210 shares the same envelope but its bore is the metric value, not this one. the AG suffix identifies the farm-duty variant of the range: sealed and flinger-protected for chaff and dust, with the catalogue deliberately derating its permissible speed versus the industrial execution. Envelope 49.2125x90x46.2 mm (1.938x3.543x1.819 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 740 g. Selection figures for YSPAG 210-115: C0/C is 0.661, Pu 0.98 kN is 2.792 % of the 35.1 kN dynamic rating, and the 740 g catalogue mass works out to roughly 15.037 g per millimetre of the 49.2125 mm bore. Outer-vs-overall width: the outer ring is 22 mm wide inside the 46.2 mm total, so the extended inner ring accounts for 0.524 of the overall width (12.1 mm of axial projection per side). Inner-geometry cross-reference: the catalogue shoulder diameters (d1 62.51 mm, d2 72 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the inner flinger. The s1 27.7 mm dimension is printed for the locking zone — the pre-drive position of the ConCentra stepped sleeve — and it is verified at mounting, not recoverable from d/D/B alone. Capacity density: 35.1 kN from 0.740 kg of bearing steel is about 47.432 kN per kilogram, and per width millimetre the 46.2 mm unit carries 0.76 kN of dynamic capacity. Sleeve geometry: the ConCentra stepped sleeve occupies the symmetric extension up to the 46.2 mm overall width while the sphered outer ring stays 22 mm wide — uniform sleeve contraction is why run-out stays low at 49.2125 mm bore.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Inspect the shaft before sleeve mounting: a single deep keyway burr or old screw-point dimple under the 46.2 mm-wide sleeve causes a local unclamped arc that later frets.
• ConCentra solves run-out and fretting but not gross misalignment — the housing spherical seat still carries that function; do not use the sleeve grip as an excuse to skip housing alignment.
• The SB shortened-inner-ring ConCentra unit needs its matching mounting sleeve and procedure; substituting a standard YSP sleeve or a generic drift is the usual cause of crooked drive-up on the 49.2125 mm shaft.
• The 35.1/23.2 kN figures belong specifically to YSPAG 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.
