      ALL BALLS offers this swingarm bearing kit for YAMAHA WR 250, WR 500, YZ 250, YZ 490 1988-1993. 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 ALL BALLS?

      Complete All Balls kits: low-friction bearings and steel-spring nitrile seals, everything you need in one box.

      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.
