How the 1726209-B-2RS1-VP274 model number is decoded

Listed in SKF 17000 chapter 2, 1726209B-2RS1/VP274 is a insert bearing with a standard (non-extended) inner ring, 45x85x19 mm overall, whose convex spherical outer ring pivots in the spherical bore of a Y-pillow, Y-flange or take-up housing. Construction is the 172-family compromise: 63-series ball geometry and standard inner ring width, contact-sealed both sides, with the convex spherical OD that makes it an insert. 1726209 belongs to the 172 family: deep-groove ball geometry to the ISO 15 03 envelope, but the outer ring OD is sphered rather than cylindrical so it pivots inside the matching housing bore. the final two digits 09 follow the standard bore-code rule (03 = 17 mm, then x5), giving a 45 mm (code 09 x 5) bore. VP274 supplies two-side NBR contact sealing for the B (lubrication-hole) execution; the holes let fresh grease reach the sphered-OD seat during servicing. Envelope 45x85x19 mm (1.772x3.346x0.748 in), outer ring 19 mm wide, C 33.2 kN, C0 21.6 kN, Pu 0.915 kN. The catalogue publishes a single speed ceiling, the limiting speed: 4,300 r/min; mass 390 g. Rating split for the maintenance file: dynamic 33.2 kN (L10), static 21.6 kN (s0 shock check), fatigue 0.915 kN (adjusted life) — three separate uses for 1726209B-2RS1/VP274, none interchangeable with another. Spherical-seat note in numbers: the 85 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 65 = 204.204 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Pitch-diameter arithmetic: dm = (45+85)/2 = 65 mm; at the 4,300 r/min limiting speed the ball set runs at dn approx 2.79x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. Mounting verification on 1726209-B-2RS1-VP274 uses the printed catalogue procedure rather than torque guessing. At the printed limiting speed of 4,300 r/min the mean diameter dm = 65 mm implies dn about 2.79x10^5 mm.r/min — the speed-demand figure used when comparing this insert with open deep-groove sizes of the same bore. Lubrication-hole note: the B execution carries outer-ring lubrication holes feeding the sphered outside surface; align the hole with the housing groove before clamping the cap, because a hole sealed off by a misaligned housing traps old grease and starves the spherical seat during re-lubrication. Fit note for 1726209-B-2RS1-VP274: because no locking device exists, shaft and housing fits do the locating work; treat the fit recommendations for sealed deep-groove bearings, and let the spherical OD pivot in the housing rather than forcing axial alignment.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• No locking device means shaft preparation is everything for 1726209-B-2RS1-VP274: observe the fit, abutment and circlip recommendations rather than expecting screws or a collar to rescue a loose shaft.
• The 45x85 mm envelope matching a 63-series bearing tempts substitution into a cylindrical housing — do not: the sphered OD only works in the mating spherical Y-housing bore.
• When ordering a like-for-like replacement, note whether the old part carried the B lubrication-hole execution: housing grooves aligned to B holes leave the non-B seal-only variant without its re-greasing path.
• The 33.2/21.6 kN figures belong specifically to 1726209B-2RS1/VP274; 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.
