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

YEL 206-2F is SKF's 30 mm-bore eccentric-locking-collar insert bearing with the inner ring extended on both sides in the YEL2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 30x62x36.5 mm. The deep-groove ball set is built into an extended inner ring carrying a separate eccentric locking collar; turning the collar against its eccentric seat pinches the shaft, and the sphered outer ring self-aligns in the housing. the YEL prefix identifies the eccentric-locking-collar design: a separate eccentric collar turns against a matching eccentric on the extended inner ring to pinch the shaft, extended both sides. the size code 206 carries the usual bore arithmetic — 30 mm (code 06 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. suffix -2F means an NBR rubber contact seal plus a plain pressed-steel flinger on EACH side: the lip rides the extended inner ring while the flinger sheds coarse contamination before it reaches the lip. Envelope 30x62x36.5 mm (1.181x2.441x1.437 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 380 g. Grease-life arithmetic is dominated by speed: at dn approx 2.90x10^5 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. Rating split for the maintenance file: dynamic 19.5 kN (L10), static 11.2 kN (s0 shock check), fatigue 0.475 kN (adjusted life) — three separate uses for YEL 206-2F, none interchangeable with another. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 39.7 mm, d2 44.1 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the plain flinger. 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. Envelope arithmetic: the radial section from 30 mm bore to 62 mm OD is 16 mm; dividing C 19.5 kN by that section gives 1.219 kN per section millimetre, and the 36.5 mm overall width is 2.281x the section. 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 18 mm outer-ring width the inner ring runs to 36.5 mm overall (48.4 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 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.
• The eccentric collar is handed to running direction; fit it wrong on the 30 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Ordering discipline for the 30 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.
