                        LEONARDO DA VINCI - Various types of axle supports - Nested axle supports, each rotating independently
                        LEONARDO DA VINCI - Various types of axle supports - Universal support, enabling the axle to move in any direction
                        LEONARDO DA VINCI - Various types of axle supports - Support for axle with two different motions
                        LEONARDO DA VINCI - Various types of axle supports - Support for axle with multiple motions
                        LEONARDO DA VINCI - Various types of axle supports - Support for axle with two transverse and two rotary motions
                        LEONARDO DA VINCI - Wear on axles and supports - Lines of wear
                        LEONARDO DA VINCI - Wear on axles and supports - Axle wear
                        LEONARDO DA VINCI - Wear on axles and supports - Support wear
                        LEONARDO DA VINCI - Systems to reduce friction on rotating axles - Lubrication
                        LEONARDO DA VINCI - Systems to reduce friction on rotating axles - Adjustable bearings
                        LEONARDO DA VINCI - Disk and roller bearings for horizontal axles - Bearings with multiple vertical disks to reduce friction on a horizontal rotating axle. Leonardo doubted the efficiency of this solution
                        LEONARDO DA VINCI - Disk and roller bearings for horizontal axles - Here, the horizontal axle rests on a single roller disk. This system offers no resistance to side-thrust
                        LEONARDO DA VINCI - Disk and roller bearings for horizontal axles - The axle rests on three disks or rollers (one under the axle, the other two on the sides). Leonardo describes this as the best solution for a fully revolving axle
                        LEONARDO DA VINCI - Disk and roller bearings for horizontal axles - Three disk sections support the axle. For Leonardo, this is the best solution for axles that does not perform complete rotations, such as bell shafts
                        LEONARDO DA VINCI - Roller and ball bearings for cone-tipped vertical axles - Bearing with mobile rollers shaped in the form of truncated cones
                        LEONARDO DA VINCI - Roller and ball bearings for cone-tipped vertical axles - Ball bearing
                        Ball bearing for cone-tipped vertical axle
                        LEONARDO DA VINCI - Pressure-resistant ball bearing
                        Pressure-resistant ball bearing
