How the YEL-210-2F model number is decoded

Listed in SKF 17000 chapter 2, YEL 210-2F is a eccentric-locking-collar insert bearing with the inner ring extended on both sides, 50x90x49.2 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 210 carries the usual bore arithmetic — 50 mm (code 10 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. -2F decodes to contact seals with additional plain flingers, one set per side; the unit is grease-filled for life and the flinger is why the sealed width exceeds the open one-side execution. Envelope 50x90x49.2 mm (1.969x3.543x1.937 in), outer ring 22 mm wide, C 35.1 kN, C0 23.2 kN, Pu 0.98 kN. Mounted width B1 62.7 mm includes the eccentric collar. The catalogue publishes a single speed ceiling, the limiting speed: 4,000 r/min; mass 920 g. Rating split for the maintenance file: dynamic 35.1 kN (L10), static 23.2 kN (s0 shock check), fatigue 0.98 kN (adjusted life) — three separate uses for YEL 210-2F, none interchangeable with another. Static-first planning: the 0.472 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 50 mm shaft, not the 35.1 kN L10 value. Envelope arithmetic: the radial section from 50 mm bore to 90 mm OD is 20 mm; dividing C 35.1 kN by that section gives 1.755 kN per section millimetre, and the 49.2 mm overall width is 2.46x the section. Load balance for documentation: C0 23.2 kN against C 35.1 kN gives a 0.661 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. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 50x90 mm insert on its chamfer tilts the whole spherical seat. Two-side sealed collar note: after driving the eccentric collar tight, lock the collar set screw against its recess and verify the collar cannot be turned by hand; a collar that was merely pressed on without the eccentric bite spins on the shaft and frets it within hours. Direction rule for YEL-210-2F: the eccentric collar self-tightens in the shaft's running direction, so mark rotation at mounting; the 50 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 62.7 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.
• The eccentric collar is handed to running direction; fit it wrong on the 50 mm shaft and self-tightening becomes self-loosening. Mark the shaft rotation before stripping any YEL2 collar unit.
• The 35.1/23.2 kN figures belong specifically to YEL 210-2F; 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.
