ROLL-FORMING GUIDE ussteel

Two basic types of roll-forming systems are utilized: a precut line and a postcut line. A precut line shears the incoming material to a specific length prior to roll-forming. During postcut line operation, the roll formed panel runs continuously and is sheared to the required length after roll-forming.

Ball and Roller Bearings Welcome to NTN Bearing

Rolling elements classify in two types: balls and rollers. Rollers come in four types: cylindrical, needle, tapered, and spherical. Balls geometrically contact with the raceway surfaces of the inner and outer rings at "points", while the contact surface of rollers is a "line" contact. Theoretically, rolling bearings are so constructed as to
