How the YET-207-107 model number is decoded

YET 207-107 is SKF's 36.512499999999996 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 36.512499999999996x72x25.4 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 three-digit -107 tail codes the bore in inches for inch-shaft bearings: 1 whole inch 7/16 in = 36.512 mm (first digit whole inches, next two sixteenths of an inch). this suffix-free execution is listed without the sealed external design: the 25.4 mm width is the one-side-extended inner ring alone, so protection depends on the housing seals and the relubrication routine rather than bearing-mounted contact seals. Envelope 36.512499999999996x72x25.4 mm (1.438x2.835x1 in), outer ring 19 mm wide, C 25.5 kN, C0 15.3 kN, Pu 0.655 kN. Mounted width B1 38.9 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 5,300 r/min; mass 440 g. Grease-life arithmetic is dominated by speed: at dn approx 2.88x10^5 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. Static-first planning: the 0.602 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 36.512499999999996 mm shaft, not the 25.5 kN L10 value. Envelope arithmetic: the radial section from 36.512499999999996 mm bore to 72 mm OD is 17.744 mm; dividing C 25.5 kN by that section gives 1.437 kN per section millimetre, and the 25.4 mm overall width is 1.431x the section. Load balance for documentation: C0 15.3 kN against C 25.5 kN gives a 0.6 ratio; mounted-unit positions with shock and standstill loading are normally checked on C0, while conveyor and fan duty are evaluated on the L10 figure. Bore-to-OD planning: OD 72 over bore 36.512499999999996 is a 1.972x step, while bore/overall-width gives 1.438; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. One-side collar note: the eccentric collar mounts on the extended side only and must turn in the shaft rotation direction to self-tighten; on reversing drives this design can loosen by design intent — choose grub-screw or ConCentra locking for true bidirectional shafts. Direction rule for YET-207-107: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 36.512499999999996 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

• The eccentric collar is handed to running direction; fit it wrong on the 36.512499999999996 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• Overall width 38.9 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 207-107 as the ecc one open execution; other order numbers of the YET 207-107 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.
