How the YSP-207-SB-2F model number is decoded

Listed in SKF 17000 chapter 2, YSP 207 SB-2F 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. -2F decodes to contact seals with additional plain flingers, one set per side; the unit is grease-filled for life and the flinger is why the sealed width exceeds the open one-side execution. 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: 5,300 r/min; mass 450 g. Grease-life arithmetic is dominated by speed: at dn approx 2.84x10^5 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. Bore-to-OD planning: OD 72 over bore 35 is a 2.057x step, while bore/overall-width gives 0.882; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. Imperial procurement cross-check: 1.378 in bore, 2.835 in OD, 1.563 in overall width; the 450 g mass converts to 0.450 kg (15.9 oz) for the bill of materials. Mass-to-load ratio for YSP-207-SB-2F: 17.647 g of catalogue mass per rated kN of C, and 12.857 g per millimetre of bore — useful when comparing executions of the same 35x72 mm envelope on the drawing. Selection figures for YSP 207 SB-2F: C0/C is 0.6, Pu 0.655 kN is 2.569 % of the 25.5 kN dynamic rating, and the 450 g catalogue mass works out to roughly 12.857 g per millimetre of the 35 mm bore. ConCentra mounting note: the SB shortened-inner-ring sleeve is driven AXIALLY with the proper sleeve/drift until it seats against the abutment — driving at an angle burrs the stepped sleeve and destroys the concentricity advantage; removal needs the matching withdrawal technique, never a puller on the flingers. Reuse note for YSP-207-SB-2F: the stepped locking sleeve is a one-time clamping component in most over-torque cases; if the 35 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

• 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 YSP 207 SB-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.
