How the YEL-206-102-2F model number is decoded

The YEL2 series order number YEL 206-102-2F is a SKF insert bearing (Y-bearing) for a 28.575 mm (1.125 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 62 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 -102 decodes as 1" +2/16, i.e. 28.575 mm; the metric coded size YEL 206 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 28.575x62x36.5 mm (1.125x2.441x1.437 in), outer ring 18 mm wide, C 19.5 kN, C0 11.2 kN, Pu 0.475 kN. Mounted width B1 48.4 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 6,300 r/min; mass 410 g. Static-first planning: the 0.307 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 28.575 mm shaft, not the 19.5 kN L10 value. At the printed limiting speed of 6,300 r/min the mean diameter dm = 45.288 mm implies dn about 2.85x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Mass-to-load ratio for YEL-206-102-2F: 21.026 g of catalogue mass per rated kN of C, and 14.348 g per millimetre of bore — useful when comparing executions of the same 28.575x62 mm envelope on the drawing. Width accounting: B1 48.4 mm covers the bearing WITH its eccentric locking collar against 36.5 mm for the bearing itself and 18 mm outer-ring width; housing axial space is drawn to B1, seal replacement space to B. Load balance for documentation: C0 11.2 kN against C 19.5 kN gives a 0.574 ratio; mounted-unit positions with shock and standstill loading are normally checked on C0, while conveyor and fan duty are evaluated on the L10 figure. 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. Direction rule for YEL-206-102-2F: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 28.575 mm shaft must be free of burrs under the collar or the eccentric cannot bed flat.

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.
• The eccentric collar is handed to running direction; fit it wrong on the 28.575 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Overall width 48.4 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.
• Ordering discipline for the 28.575 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.
