YDTech® manufacturer of logarithm profile barrel rolling elements for precision cylindrical roller bearings! supplier of overall logarithmic curve profile barrel rollers or correction line rollers in china.

what's semi-convex rollers? what's whole convex rollers? what's logarithmic curve rollers?

semi-convex, the whole convex roller refers to the roller in the plane of the plane, the outer surface of a continuous or discontinuous micro-convex arc of the basic cylindrical rollers or conical rollers, the purpose is to prevent the rollers and raceway contact stress concentration occurs at the ends. this rollers are generally defined as a convex rollers or crowned rollers.

the crown rollers is a basic cylindrical rollers and the conical roller with a continuous convexity in the plane including the roller axis and the outer surface. the logarithmic curve roller is also a convex rollers and belongs to a fully convex rollers,

the trim roller refers to a roller whose stress is concentrated to prevent the roller from contacting the raceway, and the diameter of the outer surface is slightly modified. , is a semi-convex rollers;

the whole convex rollers include: logarithmic busbar cylindrical rollers, logarithmic profile tapered rollers; the semi-convex rollers include:crowned end needle rollers, correction line needle rollers, crowned end cylindrical rollers.
