How the YSA-210-2FK-HA-2310 model number is decoded
Listed in SKF 17000 chapter 2, YSA 210-2FK HA 2310 is a tapered-bore (1:12) insert bearing supplied on its HA 2310 adapter sleeve, 42.862x90x37 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction combines capped deep-groove geometry, a tapered inner-ring bore and the supplied adapter sleeve with locknut seating — factory-grade concentricity on plain drawn shafting. YSA is the adapter-sleeve member of the Y range — tapered bore plus the HA 2310 sleeve converts a plain commercial shaft into a precisely located, demountable seat at 42.862 mm. adapter mounting means the effective bore is the sleeve bore: HA 2310 gives the 42.862 mm shaft fit with no machined shoulder required. -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 42.862x90x37 mm (1.687x3.543x1.457 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 HA 2310. The catalogue publishes a single speed ceiling, the limiting speed: 4,000 r/min; mass 1050 g. Mass-to-load ratio for YSA-210-2FK-HA-2310: 29.915 g of catalogue mass per rated kN of C, and 24.497 g per millimetre of bore — useful when comparing executions of the same 42.862x90 mm envelope on the drawing. 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 HA 2310, none interchangeable with another. 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. Bore-to-OD planning: OD 90 over bore 42.862 is a 2.1x step, while bore/overall-width gives 1.158; the spherical seat in the matching Y-housing must be specified to the 90 mm OD, not to a cylindrical housing bore. Width accounting: B1 55 mm covers the bearing WITH its adapter-sleeve hardware against 37 mm for the bearing itself and 22 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-210-2FK-HA-2310: slide HA 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
Common applications
- ventilation equipment with long through-shafts
- conveyor positions needing easy removal without shaft damage
- fan and blower shafts of plain commercial steel
Known failure patterns
- sleeve over-tightened: internal clearance vanishes and the bearing runs hot from the first hours
- sleeve under-tightened: the tapered inner ring creeps on the sleeve and polishes the taper bright
- relubricated with incompatible grease that hardens the factory fill and drags the seals
- sphered OD and spherical housing bore left dry or painted over: the static self-aligning feature freezes solid with corrosion
- pressure-greasing through the housing fitting at excessive pressure balloons the NBR seals out of their grooves
Selection pitfalls — read before you substitute
- The order number is incomplete without the sleeve: YSA-210-2FK-HA-2310 specifies the HA 2310 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 31.1 mm starting distance, not a torque value guessed from locknut size; re-measure the residual gap after tightening rather than trusting feel.
- 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.
- Catalogue ratings belong to YSA 210-2FK HA 2310 as the adapter two f execution; other order numbers of the YSA 210-2FK 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.
Frequently asked questions
What are the dimensions and catalogue data of YSA-210-2FK-HA-2310?
The catalogue envelope is 42.862x90x37 mm with a spherical outside surface; mass 1050 g. Ratings C 35.1/23.2 kN, Pu 0.98 kN, limiting speed 4,000 r/min.
What does the designation YSA 210-2FK HA 2310 mean?
YSA is the adapter-sleeve member of the Y range — tapered bore plus the HA 2310 sleeve converts a plain commercial shaft into a precisely located, demountable seat at 42.862 mm. adapter mounting means the effective bore is the sleeve bore: HA 2310 gives the 42.862 mm shaft fit with no machined shoulder required. -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.
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 (31.1 mm for this size). Too loose creeps; too tight removes internal clearance and overheats the ball set. Secure the locknut when finished.
