How the YEL-211-200-2F model number is decoded

The YEL2 series order number YEL 211-200-2F is a SKF insert bearing (Y-bearing) for a 50.8 mm (2 in) shaft: eccentric-locking-collar insert bearing with the inner ring extended on both sides, built to the ISO 15 diameter-series envelope with a sphered OD of 100 mm. Inside sits a sealed ball insert with an eccentric collar on the extended ring: collar bite locks the shaft, the contact seals retain the life grease, and the spherical OD floats in the Y-housing. YEL means collar locking instead of grub screws — fit the eccentric collar, turn it in the rotation direction until it grips, then lock the collar's own setscrew; the inner ring is extended on both sides. inch bore code -200 decodes as 2", i.e. 50.8 mm; the metric coded size YEL 211 shares the same envelope but its bore is the metric value, not this one. the -2F external design pairs a nitrile contact seal with a plain sheet-steel thrower on both sides — a two-stage exclusion chain of flinger first, sealing lip second, typical of farm and conveyor duty. Envelope 50.8x100x55.6 mm (2x3.937x2.189 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 1500 g. Static-first planning: the 0.522 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 50.8 mm shaft, not the 43.6 kN L10 value. 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. Selection figures for YEL 211-200-2F: C0/C is 0.665, Pu 1.25 kN is 2.867 % of the 43.6 kN dynamic rating, and the 1500 g catalogue mass works out to roughly 29.528 g per millimetre of the 50.8 mm bore. Envelope arithmetic: the radial section from 50.8 mm bore to 100 mm OD is 24.6 mm; dividing C 43.6 kN by that section gives 1.772 kN per section millimetre, and the 55.6 mm overall width is 2.26x the section. Bore-to-OD planning: OD 100 over bore 50.8 is a 1.969x step, while bore/overall-width gives 0.914; the spherical seat in the matching Y-housing must be specified to the 100 mm OD, not to a cylindrical housing bore. 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

• 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.
• 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.
• The eccentric collar is handed to running direction; fit it wrong on the 50.8 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Ordering discipline for the 50.8 mm size: the chapter lists several executions side by side (YEL2 locking style x seal package x application variant); a bare-number substitution needs a fresh dimension, speed and rating check rather than a like-for-like assumption.
