How the YSPAG-207 model number is decoded

Listed in SKF 17000 chapter 2, YSPAG 207 is a SKF ConCentra insert bearing with concentric stepped-sleeve locking and symmetrically extended inner ring, 35x72x39.7 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction is a sealed deep-groove insert, a symmetrically extended inner ring and the stepped ConCentra sleeve — uniform grip, minimal run-out, no shaft damage from screw points or an eccentric mass. reading YSP: SKF ConCentra technology locks the shaft through a stepped sleeve that contracts uniformly, chosen for high run-out accuracy and for shafts that must not be marked by screw points or an eccentric. the size code 207 carries the usual bore arithmetic — 35 mm (code 07 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. 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 35x72x39.7 mm (1.378x2.835x1.563 in), outer ring 19 mm wide, C 25.5 kN, C0 15.3 kN, Pu 0.655 kN. The catalogue publishes a single speed ceiling, the limiting speed: 1,100 r/min; mass 440 g. Outer-vs-overall width: the outer ring is 19 mm wide inside the 39.7 mm total, so the extended inner ring accounts for 0.521 of the overall width (10.35 mm of axial projection per side). Capacity density: 25.5 kN from 0.440 kg of bearing steel is about 57.955 kN per kilogram, and per width millimetre the 39.7 mm unit carries 0.642 kN of dynamic capacity. Fatigue-limit check: Pu 0.655 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YSPAG 207 — most belt-driven mounted-unit loads sit comfortably under 2.569 % of C. The s1 24.5 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. Static-first planning: the 0.385 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 35 mm shaft, not the 25.5 kN L10 value. Sleeve geometry: the ConCentra stepped sleeve occupies the symmetric extension up to the 39.7 mm overall width while the sphered outer ring stays 19 mm wide — uniform sleeve contraction is why run-out stays low at 35 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 39.7 mm-wide sleeve causes a local unclamped arc that later frets.
• 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 35 mm shaft.
• 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 25.5/15.3 kN figures belong specifically to YSPAG 207; 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.
