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

YSA 213-2FK HA 2313 is SKF's 55.562 mm-bore tapered-bore (1:12) insert bearing supplied on its HA 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 55.562x120x43.5 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 HA 2313 sleeve is drawn up the taper to clamp a plain 55.562 mm shaft with a locknut, giving the concentricity and easy mounting of adapter-sleeve bearings. the shaft diameter is set by the HA 2313 adapter sleeve, not by the bearing code: the sleeve seats a 55.562 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 55.562x120x43.5 mm (2.187x4.724x1.713 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 HA 2313. The catalogue publishes a single speed ceiling, the limiting speed: 3,000 r/min; mass 2100 g. Selection figures for YSA 213-2FK HA 2313: C0/C is 0.699, Pu 1.7 kN is 2.972 % of the 57.2 kN dynamic rating, and the 2100 g catalogue mass works out to roughly 37.796 g per millimetre of the 55.562 mm bore. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 82.5 mm, d3 85 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the plain flinger. Capacity density: 57.2 kN from 2.100 kg of bearing steel is about 27.238 kN per kilogram, and per width millimetre the 43.5 mm unit carries 1.315 kN of dynamic capacity. Spherical-seat note in numbers: the 120 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 87.781 = 275.772 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. 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 HA 2313, none interchangeable with another. 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. Sleeve geometry on YSA-213-2FK-HA-2313: HA 2313 pulls the tapered inner ring onto the 55.562 mm plain shaft; the printed s1 35.3 mm is the pre-drive distance and 65 mm is the overall width including the sleeve hardware.

Typical equipment & failure modes

Common applications

  • bulk conveyor positions on plain shafting
  • mill auxiliary drives with frequent bearing changes
  • heavy fan and process fan shafts

Known failure patterns

  • sleeve under-tightened: the tapered inner ring creeps on the sleeve and polishes the taper bright
  • shaft shoulder absent or too small: the sleeve pulls through the bore instead of reacting the drive-up
  • 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
  • two bearings of the same size but different locking styles swapped during overhaul — shaft preparation (dimples, collar space, sleeve seat) no longer matches

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.
  • The order number is incomplete without the sleeve: YSA-213-2FK-HA-2313 specifies the HA 2313 adapter as part of the article; quoting only the YSA bearing risks delivery of a sleeve-less tapered bore that cannot mount.
  • 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.
  • Ordering discipline for the 55.562 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.

Frequently asked questions

What are the dimensions and catalogue data of YSA-213-2FK-HA-2313?

YSA 213-2FK HA 2313 measures 55.562 mm bore x 120 mm OD x 43.5 mm overall width (outer ring 27 mm wide), 2.187 x 4.724 x 1.713 in; mass about 2100 g. SKF 17000 ratings: C 57.2 kN, C0 40 kN, Pu 1.7 kN, limiting speed 3,000 r/min.

What does the designation YSA 213-2FK HA 2313 mean?

YSA names the tapered-bore (K, 1:12 taper) insert mounted on an adapter sleeve: the HA 2313 sleeve is drawn up the taper to clamp a plain 55.562 mm shaft with a locknut, giving the concentricity and easy mounting of adapter-sleeve bearings. the shaft diameter is set by the HA 2313 adapter sleeve, not by the bearing code: the sleeve seats a 55.562 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.

What shaft preparation is needed?

A plain commercial shaft in the recommended tolerance, clean and free of burrs, with a light abutment for the sleeve face. No shoulders, dimples or collar space are required — that is the main advantage of adapter mounting.

How tight should the adapter sleeve be?

Drive-up is controlled by the printed axial procedure using the s1 starting distance (35.3 mm for this size). Too loose creeps; too tight removes internal clearance and overheats the ball set. Secure the locknut when finished.
