How the YSPAG-207-107 model number is decoded

Listed in SKF 17000 chapter 2, YSPAG 207-107 is a SKF ConCentra insert bearing with concentric stepped-sleeve locking and symmetrically extended inner ring, 36.512499999999996x72x39.7 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. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -107 = 36.512 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 36.512499999999996x72x39.7 mm (1.438x2.835x1.563 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 420 g. 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 207-107 — most belt-driven mounted-unit loads sit comfortably under 2.569 % of C. Mass-to-load ratio for YSPAG-207-107: 16.471 g of catalogue mass per rated kN of C, and 11.503 g per millimetre of bore — useful when comparing executions of the same 36.512499999999996x72 mm envelope on the drawing. 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 36.512499999999996 mm shaft, not the 25.5 kN L10 value. Envelope arithmetic: the radial section from 36.512499999999996 mm bore to 72 mm OD is 17.744 mm; dividing C 25.5 kN by that section gives 1.437 kN per section millimetre, and the 39.7 mm overall width is 2.237x the section. 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). Reuse note for YSPAG-207-107: the stepped locking sleeve is a one-time clamping component in most over-torque cases; if the 36.512499999999996 mm shaft shows a polished sleeve imprint after withdrawal, fit a new sleeve rather than re-driving the old one.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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 36.512499999999996 mm shaft.
• 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.
• 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.
• Catalogue ratings belong to YSPAG 207-107 as the concentra two ag execution; other order numbers of the YSPAG 207-107 size are different articles (open vs sealed, plain vs rubberized flinger, stainless vs carbon steel) and may carry different ratings or speeds — always quote the full designation.
