How the YEL-211-2F model number is decoded

Listed in SKF 17000 chapter 2, YEL 211-2F is a eccentric-locking-collar insert bearing with the inner ring extended on both sides, 55x100x55.6 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction pairs capped deep-groove geometry with a one-piece eccentric locking collar and a convex outer ring — quick to mount on plain commercial shafts and tolerant of initial static misalignment. reading YEL: an eccentric locking collar does the shaft clamping (popular where shaft tolerance and quick removal matter), inner ring extended symmetrically both sides. the size code 211 carries the usual bore arithmetic — 55 mm (code 11 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 55x100x55.6 mm (2.165x3.937x2.189 in), outer ring 25 mm wide, C 43.6 kN, C0 29 kN, Pu 1.25 kN. Mounted width B1 71.4 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 3,600 r/min; mass 1300 g. Selection figures for YEL 211-2F: C0/C is 0.665, Pu 1.25 kN is 2.867 % of the 43.6 kN dynamic rating, and the 1300 g catalogue mass works out to roughly 23.636 g per millimetre of the 55 mm bore. Fatigue-limit check: Pu 1.25 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YEL 211-2F — most belt-driven mounted-unit loads sit comfortably under 2.867 % of C. The s1 43.6 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. Rating split for the maintenance file: dynamic 43.6 kN (L10), static 29 kN (s0 shock check), fatigue 1.25 kN (adjusted life) — three separate uses for YEL 211-2F, none interchangeable with another. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 55x100 mm insert on its chamfer tilts the whole spherical seat. Two-side sealed collar note: after driving the eccentric collar tight, lock the collar set screw against its recess and verify the collar cannot be turned by hand; a collar that was merely pressed on without the eccentric bite spins on the shaft and frets it within hours. Collar geometry for this size: over the 25 mm outer-ring width the inner ring runs to 55.6 mm overall (71.4 mm including the eccentric collar width), giving the collar its eccentric seating face clear of the seal.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Overall width 71.4 mm includes collar space — a housing sized for a grub-screw insert of the same OD can be too narrow axially for the YEL collar.
• Never pin or weld the eccentric collar: the controlled eccentric friction is the locking principle, and pinning turns a demountable insert into a shaft-replacement job.
• The eccentric collar is handed to running direction; fit it wrong on the 55 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• The 43.6/29 kN figures belong specifically to YEL 211-2F; 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.
