摘要：An improved skateboard or roller-skate truck and wheel bearing assembly is disclosed containing an axle bearing yoke, base, grommet, and wheel and bearing combination which delivers improved steering precision, steering control, and wheel alignment. A grommet in the truck includes a bearing surface on a face which engages a bearing member in the yoke and restricts arcuate movements of the yoke and wheels. The contours of the grommet are also unique and contribute to steering control. The wheel and bearing combination incorporates paired bearing casings with bell-shaped members in their ends which meet each other inside a wheel of the board or skate and self-adjust to accommodate imperfections in the bearing seat levelness, bearing seat spacing, axle diameter and axle straightness.

主权项：1. A skateboard or roller-skate truck comprising a base plate, a yoke including a body portion moveable in arcuate paths about the base plate,a first aperture formed in the body portion, anda bearing member adjacent the first aperture, a post extending from the base plate through the first aperture adjacent the bearing member, and a resilient first grommet engaged on the post and the bearing member adjacent the first aperture adapted to restrict arcuate movements of the yoke and having a cylindrical first face configured for complementary engagement with a cylindrical surface on the bearing member.
