How the YEL-207-107-2F model number is decoded

Listed in SKF 17000 chapter 2, YEL 207-107-2F is a eccentric-locking-collar insert bearing with the inner ring extended on both sides, 36.512499999999996x72x37.6 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. for inch shafts the order number carries the bore as whole-inches plus sixteenths: -107 = 36.512 mm, which is why this row sits beside, not on, the metric bore size. -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 36.512499999999996x72x37.6 mm (1.438x2.835x1.48 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 510 g. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 36.512499999999996x72 mm insert on its chamfer tilts the whole spherical seat. At the printed limiting speed of 5,300 r/min the mean diameter dm = 54.256 mm implies dn about 2.88x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Imperial procurement cross-check: 1.438 in bore, 2.835 in OD, 1.48 in overall width; the 510 g mass converts to 0.510 kg (18.0 oz) for the bill of materials. Bore-to-OD planning: OD 72 over bore 36.512499999999996 is a 1.972x step, while bore/overall-width gives 0.971; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. Capacity density: 25.5 kN from 0.510 kg of bearing steel is about 50 kN per kilogram, and per width millimetre the 37.6 mm unit carries 0.678 kN of dynamic capacity. 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-207-107-2F: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 36.512499999999996 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 36.512499999999996 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• 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.
• Catalogue ratings belong to YEL 207-107-2F as the ecc two f execution; other order numbers of the YEL 207-107 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.
