How the YET-206-VL065 model number is decoded

YET 206/VL065 is SKF's 30 mm-bore eccentric-locking-collar insert bearing with a one-side-extended inner ring 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 30x62x23.8 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 YET 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 one side. 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 30x62x23.8 mm (1.181x2.441x0.937 in), outer ring 18 mm wide, C 19.5 kN, C0 11.2 kN, Pu 0.475 kN. Mounted width B1 35.7 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 6,300 r/min; mass 320 g. Outer-vs-overall width: the outer ring is 18 mm wide inside the 23.8 mm total, so the extended inner ring accounts for 0.244 of the overall width (5.8 mm of axial projection on the locking side). Grease-life arithmetic is dominated by speed: at dn approx 2.90x10^5 the sealed-for-life fill is planned for the catalogue's grease-life regime, which is why the limiting speed and the relubrication interval move together, and high-temperature mounts shorten both even when load is light. Width accounting: B1 35.7 mm covers the bearing WITH its eccentric locking collar against 23.8 mm for the bearing itself and 18 mm outer-ring width; housing axial space is drawn to B1, seal replacement space to B. Static-first planning: the 0.471 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 30 mm shaft, not the 19.5 kN L10 value. Bore-to-OD planning: OD 62 over bore 30 is a 2.067x step, while bore/overall-width gives 1.261; the spherical seat in the matching Y-housing must be specified to the 62 mm OD, not to a cylindrical housing bore. 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. Collar geometry for this size: over the 18 mm outer-ring width the inner ring runs to 23.8 mm overall (35.7 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

• 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 35.7 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 30 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Ordering discipline for the 30 mm size: the chapter lists several executions side by side (YEL2 locking style x seal package x application variant); a bare-number substitution needs a fresh dimension, speed and rating check rather than a like-for-like assumption.
