How the 1726207-2RS1 model number is decoded

1726207-2RS1 is SKF's 35 mm-bore insert bearing with a standard (non-extended) inner ring in the 17262 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 35x72x17 mm. Unlike the extended-ring Y executions this is a standard-width sealed deep-groove ball insert: normal-width inner ring, spherically ground outer ring, static self-alignment only through the housing seat. the 172 prefix identifies insert bearings with a STANDARD (non-extended) inner ring; 62 after it gives the sphered-OD ISO 15 dimension series 02 and 63 the series 03, so 1726207 follows the 63-series deep-groove ball envelope with a spherically ground outside surface. the final two digits 07 follow the standard bore-code rule (03 = 17 mm, then x5), giving a 35 mm (code 07 x 5) bore. -2RS1 denotes nitrile contact seals moulded directly into the outer-ring recess on both sides; there is no separate flinger, which suits the standard-inner-ring 172-execution mounted inside a sealed Y-housing. Envelope 35x72x17 mm (1.378x2.835x0.669 in), outer ring 17 mm wide, C 25.5 kN, C0 15.3 kN, Pu 0.655 kN. The catalogue publishes a single speed ceiling, the limiting speed: 6,300 r/min; mass 280 g. Mass-to-load ratio for 1726207-2RS1: 10.98 g of catalogue mass per rated kN of C, and 8 g per millimetre of bore — useful when comparing executions of the same 35x72 mm envelope on the drawing. Width accounting on this execution: 17 mm overall and 17 mm outer-ring width leave the housing designer 0 mm of inner-ring projection to accommodate the locking arrangement. Envelope arithmetic: the radial section from 35 mm bore to 72 mm OD is 18.5 mm; dividing C 25.5 kN by that section gives 1.378 kN per section millimetre, and the 17 mm overall width is 0.919x the section. Load balance for documentation: C0 15.3 kN against C 25.5 kN gives a 0.6 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. Rating split for the maintenance file: dynamic 25.5 kN (L10), static 15.3 kN (s0 shock check), fatigue 0.655 kN (adjusted life) — three separate uses for 1726207-2RS1, none interchangeable with another. 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. Geometry note: with the standard inner ring the 17 mm width and 35x72 mm bore/OD match the 63-series deep-groove ball envelope, while only the sphered outer surface identifies it as a Y-insert.

Typical equipment & failure modes

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.
• The 35x72 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.
• No locking device means shaft preparation is everything for 1726207-2RS1: observe the fit, abutment and circlip recommendations rather than expecting screws or a collar to rescue a loose shaft.
• Ordering discipline for the 35 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.
