How the YEL-208-2RF-VL065 model number is decoded

The YEL2 series order number YEL 208-2RF/VL065 is a SKF insert bearing (Y-bearing) for a 40 mm 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 80 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. the size code 208 carries the usual bore arithmetic — 40 mm (code 08 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. the VL065 treatment galvanizes the bore and both side faces of the inner ring — a targeted anti-rust option for shafts and housings in damp air, used here with the printed seal execution. Envelope 40x80x42.8 mm (1.575x3.15x1.685 in), outer ring 21 mm wide, C 30.7 kN, C0 19 kN, Pu 0.8 kN. Mounted width B1 56.3 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 2,800 r/min; mass 710 g. Width accounting: B1 56.3 mm covers the bearing WITH its eccentric locking collar against 42.8 mm for the bearing itself and 21 mm outer-ring width; housing axial space is drawn to B1, seal replacement space to B. Bore-to-OD planning: OD 80 over bore 40 is a 2x step, while bore/overall-width gives 0.935; the spherical seat in the matching Y-housing must be specified to the 80 mm OD, not to a cylindrical housing bore. Pitch-diameter arithmetic: dm = (40+80)/2 = 60 mm; at the 2,800 r/min limiting speed the ball set runs at dn approx 1.68x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. Load balance for documentation: C0 19 kN against C 30.7 kN gives a 0.619 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 40x80 mm insert on its chamfer tilts the whole spherical seat. Sealed zinc-coated collar note: VL065 covers the inner-ring bore and side faces under the -2RF seal set; the galvanized bore is slightly larger after coating, so use shafts in the lower half of the SKF tolerance band to avoid a skrink-fit that prevents collar removal. Direction rule for YEL-208-2RF-VL065: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 40 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 40 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 56.3 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 208-2RF/VL065 as the ecc two vl065 execution; other order numbers of the YEL 208 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.
