How the YET-208-VL065 model number is decoded

Listed in SKF 17000 chapter 2, YET 208/VL065 is a eccentric-locking-collar insert bearing with a one-side-extended inner ring, 40x80x29.7 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 YET: an eccentric locking collar does the shaft clamping (popular where shaft tolerance and quick removal matter), inner ring extended on one side. 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. 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 40x80x29.7 mm (1.575x3.15x1.169 in), outer ring 21 mm wide, C 30.7 kN, C0 19 kN, Pu 0.8 kN. Mounted width B1 43.2 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 4,800 r/min; mass 600 g. Spherical-seat note in numbers: the 80 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 60 = 188.496 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Capacity density: 30.7 kN from 0.600 kg of bearing steel is about 51.167 kN per kilogram, and per width millimetre the 29.7 mm unit carries 1.034 kN of dynamic capacity. Static-first planning: the 0.64 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 40 mm shaft, not the 30.7 kN L10 value. Bore-to-OD planning: OD 80 over bore 40 is a 2x step, while bore/overall-width gives 1.347; the spherical seat in the matching Y-housing must be specified to the 80 mm OD, not to a cylindrical housing bore. Rating split for the maintenance file: dynamic 30.7 kN (L10), static 19 kN (s0 shock check), fatigue 0.8 kN (adjusted life) — three separate uses for YET 208/VL065, none interchangeable with another. Zinc-coated one-side collar note: the VL065 layer protects the inner-ring bore and abutment faces; the eccentric collar itself is uncoated, so grease the collar-back interface to keep the zinc-free face from corroding fast to the inner ring. Direction rule for YET-208-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

• Overall width 43.2 mm includes collar space — a housing sized for a grub-screw insert of the same OD can be too narrow axially for the YET collar.
• 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.
• The 30.7/19 kN figures belong specifically to YET 208/VL065; 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.
