PB8 Steering Shaft Uniball 8 mm
OTT PB8 is the uniball (spherical bearing) that carries the lower end of an 8 mm kart steering shaft. It is made to OEM standards and fitted by kart manufacturers: a zinc-plated carbon-steel housing, a hardened and ground GCr15 bearing-steel ball and a bronze bushing liner, machined to tight tolerances so the shaft articulates smoothly with very little free play. A worn or low-grade steering bearing develops play, roughness or binding that dulls steering feedback — a fresh PB8 restores precise, consistent response. Dimensions 8 mm ID × 22 mm OD × 12 mm height; sold individually, retaining clip not included.
