  • These ball rollers can be used in downward and sideward applications such as with casters of push carts for transport.
  • The dustproof seal prevents the ingress of dirt and dust.
  • The body, main ball, and sub-balls are made of steel. These rollers have excellent durability.
  • Because they are fixed using screw holes in the body section, they can be attached to thin plates.
