How the 1726206-2RS1 model number is decoded

1726206-2RS1 is SKF's 30 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 30x62x16 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 1726206 follows the 63-series deep-groove ball envelope with a spherically ground outside surface. the final two digits 06 follow the standard bore-code rule (03 = 17 mm, then x5), giving a 30 mm (code 06 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 30x62x16 mm (1.181x2.441x0.63 in), outer ring 16 mm wide, C 19.5 kN, C0 11.2 kN, Pu 0.475 kN. The catalogue publishes a single speed ceiling, the limiting speed: 7,500 r/min; mass 190 g. Bore-to-OD planning: OD 62 over bore 30 is a 2.067x step, while bore/overall-width gives 1.875; the spherical seat in the matching Y-housing must be specified to the 62 mm OD, not to a cylindrical housing bore. Rating split for the maintenance file: dynamic 19.5 kN (L10), static 11.2 kN (s0 shock check), fatigue 0.475 kN (adjusted life) — three separate uses for 1726206-2RS1, none interchangeable with another. Imperial procurement cross-check: 1.181 in bore, 2.441 in OD, 0.63 in overall width; the 190 g mass converts to 0.190 kg (6.7 oz) for the bill of materials. Fillet discipline: the printed r_min 1 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 30x62 mm insert on its chamfer tilts the whole spherical seat. Selection figures for 1726206-2RS1: C0/C is 0.574, Pu 0.475 kN is 2.436 % of the 19.5 kN dynamic rating, and the 190 g catalogue mass works out to roughly 6.333 g per millimetre of the 30 mm bore. 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 1726206-2RS1: 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

Selection pitfalls — read before you substitute

• The 30x62 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.
• No locking device means shaft preparation is everything for 1726206-2RS1: observe the fit, abutment and circlip recommendations rather than expecting screws or a collar to rescue a loose shaft.
• Catalogue ratings belong to 1726206-2RS1 as the standard std rs1 execution; other order numbers of the 1726206 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.
