How the YSA-210-2FK-H-2310 model number is decoded

The YSA2 series order number YSA 210-2FK H 2310 is a SKF insert bearing (Y-bearing) for a 45 mm shaft: tapered-bore (1:12) insert bearing supplied on its H 2310 adapter sleeve, built to the ISO 15 diameter-series envelope with a sphered OD of 90 mm. Inside is a sealed, symmetrically extended ball insert with a tapered bore, the adapter sleeve converting a plain commercial shaft into a precision seat without shoulders, screw points or collars. reading YSA: the inner-ring bore is tapered 1:12 and the bearing ships/specifies with its H 2310 adapter sleeve; driving the sleeve home locks the plain shaft without shoulders or screw points. read the 45 mm bore from the H 2310 sleeve designation — the YSA code marks the bearing seat size and the sleeve series is offset by one (sleeve code 310 clamps the 45 mm shaft). the -2F external design pairs a nitrile contact seal with a plain sheet-steel thrower on both sides — a two-stage exclusion chain of flinger first, sealing lip second, typical of farm and conveyor duty. Envelope 45x90x37 mm (1.772x3.543x1.457 in), outer ring 22 mm wide, C 35.1 kN, C0 23.2 kN, Pu 0.98 kN. Mounted width B1 55 mm includes the adapter sleeve. Supplied/specified with H 2310. The catalogue publishes a single speed ceiling, the limiting speed: 4,000 r/min; mass 970 g. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 62.5 mm, d3 70 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the plain flinger. 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. Pitch-diameter arithmetic: dm = (45+90)/2 = 67.5 mm; at the 4,000 r/min limiting speed the ball set runs at dn approx 2.70x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. The s1 31.1 mm dimension is printed for the locking zone — the distance before the adapter sleeve is driven up the taper — and it is verified at mounting, not recoverable from d/D/B alone. 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 YSA 210-2FK H 2310, 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. Mounting sequence for YSA-210-2FK-H-2310: slide H 2310 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 31.1 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-210-2FK-H-2310 specifies the H 2310 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 45 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.
