How the YEL-206-2RF-VL065 model number is decoded

YEL 206-2RF/VL065 is SKF's 30 mm-bore eccentric-locking-collar insert bearing with the inner ring extended on both sides in the YEL2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 30x62x36.5 mm. The deep-groove ball set is built into an extended inner ring carrying a separate eccentric locking collar; turning the collar against its eccentric seat pinches the shaft, and the sphered outer ring self-aligns in the housing. the YEL prefix identifies the eccentric-locking-collar design: a separate eccentric collar turns against a matching eccentric on the extended inner ring to pinch the shaft, extended both sides. the size code 206 carries the usual bore arithmetic — 30 mm (code 06 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. /VL065 means the inner-ring bore and side faces are zinc coated: corrosion protection on the shaft seating and abutment faces without changing the seal package or the carbon-steel outer ring. Envelope 30x62x36.5 mm (1.181x2.441x1.437 in), outer ring 18 mm wide, C 19.5 kN, C0 11.2 kN, Pu 0.475 kN. Mounted width B1 48.4 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 3,800 r/min; mass 380 g. Imperial procurement cross-check: 1.181 in bore, 2.441 in OD, 1.437 in overall width; the 380 g mass converts to 0.380 kg (13.4 oz) for the bill of materials. Speed ceiling of 3,800 r/min is the catalogue mechanical limit for THIS execution; seal lip and flinger drag, not steel fatigue, are normally what cap it, so real fan duty is planned well below it. Bore-to-OD planning: OD 62 over bore 30 is a 2.067x step, while bore/overall-width gives 0.822; the spherical seat in the matching Y-housing must be specified to the 62 mm OD, not to a cylindrical housing bore. Pitch-diameter arithmetic: dm = (30+62)/2 = 46 mm; at the 3,800 r/min limiting speed the ball set runs at dn approx 1.75x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. Width accounting: B1 48.4 mm covers the bearing WITH its eccentric locking collar against 36.5 mm for the bearing itself and 18 mm outer-ring width; housing axial space is drawn to B1, seal replacement space to B. 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. Collar geometry for this size: over the 18 mm outer-ring width the inner ring runs to 36.5 mm overall (48.4 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

• The eccentric collar is handed to running direction; fit it wrong on the 30 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Overall width 48.4 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 206-2RF/VL065 as the ecc two vl065 execution; other order numbers of the YEL 206 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.
