How the YEL-212-207-2F model number is decoded

The YEL2 series order number YEL 212-207-2F is a SKF insert bearing (Y-bearing) for a 61.912499999999994 mm (2.438 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 110 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 -207 decodes as 2" +7/16, i.e. 61.912 mm; the metric coded size YEL 212 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 61.912499999999994x110x61.9 mm (2.438x4.331x2.437 in), outer ring 26 mm wide, C 52.7 kN, C0 36 kN, Pu 1.53 kN. Mounted width B1 77.8 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 3,400 r/min; mass 1600 g. Fatigue-limit check: Pu 1.53 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YEL 212-207-2F — most belt-driven mounted-unit loads sit comfortably under 2.903 % of C. Spherical-seat note in numbers: the 110 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 85.956 = 270.039 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Bore-to-OD planning: OD 110 over bore 61.912499999999994 is a 1.777x step, while bore/overall-width gives 1; the spherical seat in the matching Y-housing must be specified to the 110 mm OD, not to a cylindrical housing bore. Imperial procurement cross-check: 2.438 in bore, 4.331 in OD, 2.437 in overall width; the 1600 g mass converts to 1.600 kg (56.4 oz) for the bill of materials. Mass-to-load ratio for YEL-212-207-2F: 30.361 g of catalogue mass per rated kN of C, and 25.843 g per millimetre of bore — useful when comparing executions of the same 61.912499999999994x110 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. Direction rule for YEL-212-207-2F: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 61.912499999999994 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

• Overall width 77.8 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.
• The eccentric collar is handed to running direction; fit it wrong on the 61.912499999999994 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• The 52.7/36 kN figures belong specifically to YEL 212-207-2F; HV stainless, AG agricultural and VE495 zinc-plated variants of the same envelope publish derated values, so write the complete order number including suffixes on the purchase and maintenance records.
