How the YAR-207-2RFGR-HV model number is decoded
YAR 207-2RFGR/HV is SKF's 35 mm-bore grub-screw insert bearing with the inner ring extended on both sides in the YAR2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 35x72x42.9 mm. Wide-inner-ring deep-groove ball geometry carries the load: the extended inner ring gives the shaft grip and the seal lands, while the outer ring stays narrow and spherically ground on its outside surface. the YAR prefix names SKF grub-screw Y-bearings: two set screws in the extended inner ring lock the shaft at a 120 deg angle, and the inner ring extends symmetrically on both sides. the size code 207 carries the usual bore arithmetic — 35 mm (code 07 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. /HV identifies the stainless-steel, food-industry execution: stainless bearing components, food-compatible rubber in the seal/flinger set and food-grade grease fill — the catalogue ratings are correspondingly below the standard steel version, and the GR marking adds the lubrication groove in the sphered outside surface on the locking side. Envelope 35x72x42.9 mm (1.378x2.835x1.689 in), outer ring 19 mm wide, C 21.6 kN, C0 15.3 kN, Pu 0.655 kN. The catalogue publishes a single speed ceiling, the limiting speed: 3,200 r/min; mass 450 g. Static-first planning: the 0.357 kN of C0 per overall-width millimetre is the figure for belt tension peaks and rotor imbalance standstill loads on the 35 mm shaft, not the 21.6 kN L10 value. Grease-life arithmetic is dominated by speed: at dn approx 1.71x10^5 the sealed-for-life fill is planned for the catalogue's grease-life regime, which is why the limiting speed and the relubrication interval move together, and high-temperature mounts shorten both even when load is light. Pitch-diameter arithmetic: dm = (35+72)/2 = 53.5 mm; at the 3,200 r/min limiting speed the ball set runs at dn approx 1.71x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. Bore-to-OD planning: OD 72 over bore 35 is a 2.057x step, while bore/overall-width gives 0.816; the spherical seat in the matching Y-housing must be specified to the 72 mm OD, not to a cylindrical housing bore. Selection figures for YAR 207-2RFGR/HV: C0/C is 0.708, Pu 0.655 kN is 3.032 % of the 21.6 kN dynamic rating, and the 450 g catalogue mass works out to roughly 12.857 g per millimetre of the 35 mm bore. Stainless food-range note: HV parts trade some capacity for corrosion resistance and food-compatible lubrication, and the printed limiting speed is set for that fill; do not top up with ordinary mineral grease in service — mixing greases can harden the food-grade fill and seize the seals. Service tip for YAR-207-2RFGR-HV: dimpled or drilled shaft spots under the screw points are sometimes specified on shock duty, but the standard mounting relies on point indentation alone — never substitute longer screws that reach the 18.5 mm radial section.
Typical equipment & failure modes
Common applications
- garden and groundcare equipment
- head- and tail-shaft pillow blocks in unit handling
- trough conveyor idler drives
Known failure patterns
- over-tightened screw points dimple the shaft so deeply that the bearing cannot be removed without machining
- hammering the bearing onto a tight shaft through the outer ring brinells the ball tracks before first start-up
- 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
- pressure-greasing through the housing fitting at excessive pressure balloons the NBR seals out of their grooves
Selection pitfalls — read before you substitute
- Replacement discipline: a YAR insert is not interchangeable with an eccentric-collar unit of the same envelope — the shaft may need spot-facing or collar space that does not exist.
- Do not specify the 35 mm grub-screw insert for a shaft harder than about 45 HRC without dimples: the screw points skate on hard surfaces and the unit creeps regardless of tightening torque.
- The 25.4 mm s1 dimension is the screw seating geometry inside the 23.9 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
- Ordering discipline for the 35 mm size: the chapter lists several executions side by side (YAR2 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 YAR-207-2RFGR-HV?
YAR 207-2RFGR/HV measures 35 mm bore x 72 mm OD x 42.9 mm overall width (outer ring 19 mm wide), 1.378 x 2.835 x 1.689 in; mass about 450 g. SKF 17000 ratings: C 21.6 kN, C0 15.3 kN, Pu 0.655 kN, limiting speed 3,200 r/min.
What does the designation YAR 207-2RFGR/HV mean?
the YAR prefix names SKF grub-screw Y-bearings: two set screws in the extended inner ring lock the shaft at a 120 deg angle, and the inner ring extends symmetrically on both sides. the size code 207 carries the usual bore arithmetic — 35 mm (code 07 x 5) — while the leading 2 marks the ISO 15 diameter series 2 sphered-OD envelope. /HV identifies the stainless-steel, food-industry execution: stainless bearing components, food-compatible rubber in the seal/flinger set and food-grade grease fill — the catalogue ratings are correspondingly below the standard steel version, and the GR marking adds the lubrication groove in the sphered outside surface on the locking side.
What is the difference between YAT and YAR?
YAT has the inner ring extended on ONE side (and in this chapter is the open execution); YAR extends the inner ring symmetrically on BOTH sides and is delivered with seal/flinger packages such as -2F or -2RF. Bore, OD and ball set are shared; overall width and sealing differ.
Can a grub-screw insert replace an eccentric-collar one?
Not without checking shaft and housing preparation: collar units need axial space for the collar and rely on rotation-direction self-tightening, while grub screws need clean shaft spots under the points. Same envelope does not mean same mounting.
