The invention relates to an eyebolt for releasably connecting a carrying, lashing or traction means with an object, comprising a threaded bolt (2) and an eyelet (3), wherein the threaded bolt (2) has an inner bearing part (10) and the eyelet (3) is connected to an outer bearing part (4) which with the incorporation of rolling elements (12a, 12b) is supported on the inner bearing part (10), wherein the rolling elements (12a, 12b) are disposed above one another in a ring around the inner bearing part (10) in at least two planes (E1, E2) extending spaced apart and parallel to one another, wherein: rolling elements (12a) disposed in a first plane (E1) have a radius and rolling elements (12b) disposed in a second plane (E2) have a radius. In this case the sum of the radius of one of the rolling elements (12a) disposed in the first plane (E1) and the radius of one of the rolling elements (12b) disposed in the second plane (E2) is greater than the spacing between the planes (E1, E2) extending parallel to one another.

An eyebolt for releasably connecting a carrying, lashing or traction member with an object, comprising:
The eyebolt of claim 17, wherein any two rolling bodies arranged immediately behind one another in one of the planes have a point contact with at least one of the rolling bodies in the other one of the planes.
The eyebolt of claim 17, wherein any two rolling bodies arranged immediately behind one another in one of the planes have a line contact with at least one of the rolling bodies in the other one of the planes.
The eyebolt of claim 17, wherein any three rolling bodies define an angle of 60° to less than 180° there between, with two of these rolling bodies being arranged jointly in one of the planes while the remaining rolling body lies in the other one of the planes.
The eyebolt of claim 17, wherein at least one of the outer bearing part and the inner bearing part has a roller groove arranged in each of the planes and having a rounded cross section.
The eyebolt of claim 17, wherein the inner bearing part is defined by a height extending in a longitudinal direction of the inner bearing part, and the outer bearing part is defined by a height extending in the longitudinal direction and embracing the inner bearing part, said height of the inner bearing part corresponding at a maximum to the height of the outer bearing part.
The eyebolt of claim 17, wherein the outer bearing part has a conical outer surface.
The eyebolt of claim 17, wherein the threaded bolt is formed in one piece with the inner bearing part.
The eyebolt of claim 17, wherein the inner bearing part has a tool engagement contour at an end face distal to the threaded bolt.
The eyebolt of claim 17, wherein the eyelet is formed in one piece with the outer bearing part.
The eyebolt of claim 17, wherein the first and second pluralities of the rolling bodies in the planes are identical.
The eyebolt of claim 17, wherein the first and second pluralities of the rolling bodies arranged in the planes are oriented above one another in parallel relation or at an angle in relation to a longitudinal direction of the inner bearing part.
The eyebolt of claim 17, wherein the rolling bodies are formed as ball, cylinder, or truncated cone.
The eyebolt of claim 17, wherein the first and second pluralities of the rolling bodies arranged in the planes have identical dimensions.
