How the YSA-213-2FK-HE-2313 model number is decoded

YSA 213-2FK HE 2313 is SKF's 57.15 mm-bore tapered-bore (1:12) insert bearing supplied on its HE 2313 adapter sleeve in the YSA2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 57.15x120x43.5 mm. The inner ring carries a 1:12 tapered bore and mounts on the specified adapter sleeve: tightening the sleeve nut draws the ring home on a plain shaft, while the sphered outer ring pivots in the Y-housing. YSA names the tapered-bore (K, 1:12 taper) insert mounted on an adapter sleeve: the HE 2313 sleeve is drawn up the taper to clamp a plain 57.15 mm shaft with a locknut, giving the concentricity and easy mounting of adapter-sleeve bearings. the shaft diameter is set by the HE 2313 adapter sleeve, not by the bearing code: the sleeve seats a 57.15 mm plain shaft under the tapered bore. suffix -2F means an NBR rubber contact seal plus a plain pressed-steel flinger on EACH side: the lip rides the extended inner ring while the flinger sheds coarse contamination before it reaches the lip. Envelope 57.15x120x43.5 mm (2.25x4.724x1.713 in), outer ring 27 mm wide, C 57.2 kN, C0 40 kN, Pu 1.7 kN. Mounted width B1 65 mm includes the adapter sleeve. Supplied/specified with HE 2313. The catalogue publishes a single speed ceiling, the limiting speed: 3,000 r/min; mass 2050 g. Load balance for documentation: C0 40 kN against C 57.2 kN gives a 0.699 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. Rating split for the maintenance file: dynamic 57.2 kN (L10), static 40 kN (s0 shock check), fatigue 1.7 kN (adjusted life) — three separate uses for YSA 213-2FK HE 2313, none interchangeable with another. Mass-to-load ratio for YSA-213-2FK-HE-2313: 35.839 g of catalogue mass per rated kN of C, and 35.871 g per millimetre of bore — useful when comparing executions of the same 57.15x120 mm envelope on the drawing. Bore-to-OD planning: OD 120 over bore 57.15 is a 2.1x step, while bore/overall-width gives 1.314; the spherical seat in the matching Y-housing must be specified to the 120 mm OD, not to a cylindrical housing bore. Width accounting: B1 65 mm covers the bearing WITH its adapter-sleeve hardware against 43.5 mm for the bearing itself and 27 mm outer-ring width; housing axial space is drawn to B1, seal replacement space to B. Adapter-sleeve note: tighten the sleeve locknut to the catalogue axial drive-up (s1 is printed as the starting distance before the sleeve is driven into the tapered bore); under-tightening lets the inner ring creep, over-tightening eliminates internal clearance and preloads the balls hot. Mounting sequence for YSA-213-2FK-HE-2313: slide HE 2313 on first, seat the bearing in the housing register, then draw the nut to drive-up — reversing the order (sleeve fully tightened before housing engagement) locks in misalignment the sphered seat cannot cure.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Plain-shaft advantage is also its trap: with no shoulders, axial location comes entirely from the sleeve/nut reaction — the abutment behind the sleeve must be square and present.
• Sleeve drive-up uses the printed s1 35.3 mm starting distance, not a torque value guessed from locknut size; re-measure the residual gap after tightening rather than trusting feel.
• The order number is incomplete without the sleeve: YSA-213-2FK-HE-2313 specifies the HE 2313 adapter as part of the article; quoting only the YSA bearing risks delivery of a sleeve-less tapered bore that cannot mount.
• Ordering discipline for the 57.15 mm size: the chapter lists several executions side by side (YSA2 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.
