How the YET-205-VL065 model number is decoded
Listed in SKF 17000 chapter 2, YET 205/VL065 is a eccentric-locking-collar insert bearing with a one-side-extended inner ring, 25x52x21.5 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 205 carries the usual bore arithmetic — 25 mm — 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 25x52x21.5 mm (0.984x2.047x0.846 in), outer ring 15 mm wide, C 14 kN, C0 7.8 kN, Pu 0.335 kN. Mounted width B1 31 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 7,000 r/min; mass 200 g. Grease-life arithmetic is dominated by speed: at dn approx 2.69x10^5 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. Imperial procurement cross-check: 0.984 in bore, 2.047 in OD, 0.846 in overall width; the 200 g mass converts to 0.200 kg (7.1 oz) for the bill of materials. Fillet discipline: the printed r_min 0.6 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 25x52 mm insert on its chamfer tilts the whole spherical seat. The s1 23.5 mm dimension is printed for the locking zone — the set-screw/collar seating reference — and it is verified at mounting, not recoverable from d/D/B alone. At the printed limiting speed of 7,000 r/min the mean diameter dm = 38.5 mm implies dn about 2.69x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same 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. Direction rule for YET-205-VL065: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 25 mm shaft must be free of burrs under the collar or the eccentric cannot bed flat.
Typical equipment & failure modes
Common applications
- ventilation equipment with frequent bearing changes
- agricultural machinery PTO-driven shafts
- tiller and cultivator rotors
Known failure patterns
- burr or paint under the eccentric faces prevents full bite, leaving an eccentric preload that runs hot
- collar forced on a reversing application repeatedly loads and unloads the eccentric, fretting both parts
- pressure-greasing through the housing fitting at excessive pressure balloons the NBR seals out of their grooves
- sphered OD and spherical housing bore left dry or painted over: the static self-aligning feature freezes solid with corrosion
- relubricated with incompatible grease that hardens the factory fill and drags the seals
Selection pitfalls — read before you substitute
- The eccentric collar is handed to running direction; fit it wrong on the 25 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
- Overall width 31 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.
- 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 YET 205/VL065 as the ecc one vl065 execution; other order numbers of the YET 205 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.
Frequently asked questions
What are the dimensions and catalogue data of YET-205-VL065?
The catalogue envelope is 25x52x21.5 mm with a spherical outside surface; mass 200 g. Ratings C 14/7.8 kN, Pu 0.335 kN, limiting speed 7,000 r/min.
What does the designation YET 205/VL065 mean?
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 205 carries the usual bore arithmetic — 25 mm — 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.
What is the difference between YET and YEL?
YET has the inner ring extended on one side; YEL extends it on both sides. Both lock with the eccentric collar and share bore/OD geometry; the sealed -2F executions sit in the YEL listings.
Can eccentric-collar bearings run in both directions?
They are intended for one predominant running direction; true reversing drives can unwind the eccentric. For bidirectional or vibrating shafts choose grub-screw or SKF ConCentra (YSP) locking.
