How the YEL-207-2RF-VL065 model number is decoded

Listed in SKF 17000 chapter 2, YEL 207-2RF/VL065 is a eccentric-locking-collar insert bearing with the inner ring extended on both sides, 35x72x37.6 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. the size code 207 carries the usual bore arithmetic — 35 mm (code 07 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. VL065 adds zinc coating exactly where the inner ring meets the shaft and abutments; the rest of the bearing follows the standard design of the YEL2 size. Envelope 35x72x37.6 mm (1.378x2.835x1.48 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: 3,200 r/min; mass 540 g. Selection figures for YEL 207-2RF/VL065: C0/C is 0.6, Pu 0.655 kN is 2.569 % of the 25.5 kN dynamic rating, and the 540 g catalogue mass works out to roughly 15.429 g per millimetre of the 35 mm bore. Capacity density: 25.5 kN from 0.540 kg of bearing steel is about 47.222 kN per kilogram, and per width millimetre the 37.6 mm unit carries 0.678 kN of dynamic capacity. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 46.1 mm, d2 51.1 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the inner flinger. Spherical-seat note in numbers: the 72 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 53.5 = 168.075 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Imperial procurement cross-check: 1.378 in bore, 2.835 in OD, 1.48 in overall width; the 540 g mass converts to 0.540 kg (19.0 oz) for the bill of materials. 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 19 mm outer-ring width the inner ring runs to 37.6 mm overall (51.1 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 35 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• 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.
• 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 207-2RF/VL065 as the ecc two vl065 execution; other order numbers of the YEL 207 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.
