How the 1726212-2RS1 model number is decoded
The 17262 series order number 1726212-2RS1 is a SKF insert bearing (Y-bearing) for a 60 mm shaft: insert bearing with a standard (non-extended) inner ring, built to the ISO 15 diameter-series envelope with a sphered OD of 110 mm. The unit is a capped deep-groove ball bearing to the ISO 15 03 envelope whose outer surface is sphered instead of cylindrical, so it combines a standard fit with Y-housing alignment. reading 1726xx: 172 = insert bearing with a standard-width inner ring, 6 = ISO 15 dimension series 03 with a spherically shaped outside surface for self-aligning in a Y-housing. the final two digits 12 follow the standard bore-code rule (03 = 17 mm, then x5), giving a 60 mm (code 12 x 5) bore. the -2RS1 suffix is the classic contact NBR seal on each side without add-on flingers — grease retention for life inside the sphered-OD ISO 15 envelope. Envelope 60x110x22 mm (2.362x4.331x0.866 in), outer ring 22 mm wide, C 52.7 kN, C0 36 kN, Pu 1.53 kN. The catalogue publishes a single speed ceiling, the limiting speed: 4,000 r/min; mass 770 g. Capacity density: 52.7 kN from 0.770 kg of bearing steel is about 68.442 kN per kilogram, and per width millimetre the 22 mm unit carries 2.395 kN of dynamic capacity. Static-first planning: the 1.636 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 60 mm shaft, not the 52.7 kN L10 value. Mounting verification on 1726212-2RS1 uses the printed catalogue procedure rather than torque guessing. Spherical-seat note in numbers: the 110 mm OD is ground spherical, so the self-aligning pivot happens on a circle roughly pi x 85 = 267.035 mm in mean circumference — keep that interface greased, because corrosion locking turns the pivot into a fixed misaligned mount. Fatigue-limit check: Pu 1.53 kN is the equivalent-load threshold under which the SKF adjusted-rating model credits very long life for 1726212-2RS1 — most belt-driven mounted-unit loads sit comfortably under 2.903 % of C. Standard-inner-ring note: unlike YAR/YEL/YSP inserts this 172 execution has NO shaft locking device and NO extended ring — it locates by fits like a normal sealed deep-groove ball bearing, while the sphered outside surface still provides static self-alignment inside the Y-housing. Fit note for 1726212-2RS1: 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
Common applications
- process positions where the spherical seat and a normal fit are both required
- heavy Y-housed conveyor and fan shafts
Known failure patterns
- VP274/B lubrication holes blocked by a misaligned housing groove starve the spherical seat during re-greasing
- treated as a normal cylindrical-OD bearing and pressed into a plain bore: the sphered outer surface cannot locate radially without the matching spherical housing seat
- two bearings of the same size but different locking styles swapped during overhaul — shaft preparation (dimples, collar space, sleeve seat) no longer matches
- 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
Selection pitfalls — read before you substitute
- 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.
- No locking device means shaft preparation is everything for 1726212-2RS1: observe the fit, abutment and circlip recommendations rather than expecting screws or a collar to rescue a loose shaft.
- The 60x110 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.
- Ordering discipline for the 60 mm size: the chapter lists several executions side by side (17262 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 1726212-2RS1?
Boundary dimensions: bore 60 mm, sphered OD 110 mm, overall width 22 mm; weight 770 g. Loads: dynamic 52.7 kN, static 36 kN, fatigue 1.53 kN; the only published speed is the 4,000 r/min limiting value.
What does the designation 1726212-2RS1 mean?
reading 1726xx: 172 = insert bearing with a standard-width inner ring, 6 = ISO 15 dimension series 03 with a spherically shaped outside surface for self-aligning in a Y-housing. the final two digits 12 follow the standard bore-code rule (03 = 17 mm, then x5), giving a 60 mm (code 12 x 5) bore. the -2RS1 suffix is the classic contact NBR seal on each side without add-on flingers — grease retention for life inside the sphered-OD ISO 15 envelope.
What do B and VP274 mean?
B denotes lubrication holes in the outer ring (only on standard-inner-ring executions); VP274 is the NBR contact-seal package on both sides. The B-2RS1/VP274 article is therefore sealed yet re-lubricatable through the housing.
Is 1726212-2RS1 the same as a 6312 sealed deep-groove bearing?
The 60x110x22 mm envelope and ratings follow the 63-series plan, but the OUTER surface is spherically ground for a Y-housing; pressing it into a normal cylindrical bore defeats its design. Treat it as an insert, not a drop-in 63-bearing.
