1899 Article Ball Bearing Surfaces Ole Lunde Elgin IL - ORIGINAL SCA2

This is an original 1899 one page article on ball bearings patented by Oley Lunde of Elgin, Illinois. These bearing surfaces are formed by two collars on the axle, one adjustable toward the other, and an intermediate ring. This ring has a pin which projects in to a recess or groove in the axle, whereby the ring is free to slide longitudinally along the axle but is made to rotate with the axle. The automatic adjustment of the sliding bearing ring on the axle and the series of separating balls are designed to prevent sliding friction and grinding and to distribute the load evenly on the two series of bearing balls.
