How the YEL-207-106-2F model number is decoded

YEL 207-106-2F is SKF's 34.925 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 34.925x72x37.6 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 three-digit -106 tail codes the bore in inches for inch-shaft bearings: 1 whole inch 6/16 in = 34.925 mm (first digit whole inches, next two sixteenths of an inch). 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 34.925x72x37.6 mm (1.375x2.835x1.48 in), outer ring 19 mm wide, C 25.5 kN, C0 15.3 kN, Pu 0.655 kN. Mounted width B1 51.1 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 5,300 r/min; mass 550 g. Spherical-seat note in numbers: the 72 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 53.462 = 167.956 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Imperial procurement cross-check: 1.375 in bore, 2.835 in OD, 1.48 in overall width; the 550 g mass converts to 0.550 kg (19.4 oz) for the bill of materials. Width accounting: B1 51.1 mm covers the bearing WITH its eccentric locking collar against 37.6 mm for the bearing itself and 19 mm outer-ring width; housing axial space is drawn to B1, seal replacement space to B. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 34.925x72 mm insert on its chamfer tilts the whole spherical seat. Mass-to-load ratio for YEL-207-106-2F: 21.569 g of catalogue mass per rated kN of C, and 15.748 g per millimetre of bore — useful when comparing executions of the same 34.925x72 mm envelope on the drawing. 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 19 mm outer-ring width the inner ring runs to 37.6 mm overall (51.1 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 51.1 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 34.925 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Ordering discipline for the 34.925 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.
