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

Listed in SKF 17000 chapter 2, YEL 207-2F is a eccentric-locking-collar insert bearing with the inner ring extended on both sides, 35x72x37.6 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 207 carries the usual bore arithmetic — 35 mm (code 07 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 35x72x37.6 mm (1.378x2.835x1.48 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 540 g. At the printed limiting speed of 5,300 r/min the mean diameter dm = 53.5 mm implies dn about 2.84x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Load balance for documentation: C0 15.3 kN against C 25.5 kN gives a 0.6 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. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 35x72 mm insert on its chamfer tilts the whole spherical seat. Spherical-seat note in numbers: the 72 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 53.5 = 168.075 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. The s1 32.3 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. 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-207-2F: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 35 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

• The eccentric collar is handed to running direction; fit it wrong on the 35 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• 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.
• 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.
• Catalogue ratings belong to YEL 207-2F as the ecc two f execution; other order numbers of the YEL 207 size are different articles (open vs sealed, plain vs rubberized flinger, stainless vs carbon steel) and may carry different ratings or speeds — always quote the full designation.
