The bearings that let the swingarm pivot freely so the rear suspension works properly.
PIVOT WORKS offers this swingarm bearing kit for YAMAHA YZ 250, YZ 490 1986-1987. The swingarm pivots on needle bearings protected by seals. Water and mud make them seize: the suspension gets stiff and play appears.
What is this bearing made of?
Races and balls in hardened chrome steel, 100Cr6 type, very hard and fatigue-resistant, protected by rubber seals.
- Double seal (2RS): a seal on each side, very well sealed against water and mud, essential off-road.
- Limit: slightly more drag than a metal-shielded bearing (ZZ), which spins more freely but seals far less well.
- Fitting: press or drift it in on the outer race, never hammer on the seal; keep the pressure washer away from the hubs.
Why choose PIVOT WORKS?
Pivot Works kits, sold by the American All Balls Racing group, use hardened NTN, NSK or Koyo bearings from original-equipment bearing suppliers, supplied pre-greased with their seals; every kit carries the Pivot Works limited lifetime warranty.
When should you replace this part?
Side play when you rock the swingarm with the rear wheel removed, or a notchy movement: the bearings need changing.
