How the YEL-210-115-2F model number is decoded

The YEL2 series order number YEL 210-115-2F is a SKF insert bearing (Y-bearing) for a 49.2125 mm (1.938 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 90 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 -115 decodes as 1" +15/16, i.e. 49.212 mm; the metric coded size YEL 210 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 49.2125x90x49.2 mm (1.938x3.543x1.937 in), outer ring 22 mm wide, C 35.1 kN, C0 23.2 kN, Pu 0.98 kN. Mounted width B1 62.7 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 4,000 r/min; mass 950 g. Pitch-diameter arithmetic: dm = (49.2125+90)/2 = 69.606 mm; at the 4,000 r/min limiting speed the ball set runs at dn approx 2.78x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. The s1 38.1 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. Fatigue-limit check: Pu 0.98 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for YEL 210-115-2F — most belt-driven mounted-unit loads sit comfortably under 2.792 % of C. Envelope arithmetic: the radial section from 49.2125 mm bore to 90 mm OD is 20.394 mm; dividing C 35.1 kN by that section gives 1.721 kN per section millimetre, and the 49.2 mm overall width is 2.413x the section. Outer-vs-overall width: the outer ring is 22 mm wide inside the 49.2 mm total, so the extended inner ring accounts for 0.553 of the overall width (13.6 mm of axial projection per side). 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 22 mm outer-ring width the inner ring runs to 49.2 mm overall (62.7 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

• Overall width 62.7 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 49.2125 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• The 35.1/23.2 kN figures belong specifically to YEL 210-115-2F; 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.
