1.2.1Super Roller Chain High performance: General uses
Application Example Super Roller Chains are generally used in compact drives because they have high maximum allowable tension. (See Figure 1.3.)
Figure 1.3 Super Roller Chain
Construction and Features Super Roller Chains are constructed for added fatigue strength (Table 1.2). In addition, there are several characteristics that distinguish Super Roller Chains. (1) Appearance • The plate shape is almost flat. • Quad-staked riveting on the pin helps hold the link plate. • The roller is seamless, not curled. (2) Construction • The pins are made of through hardened steel, which provides toughness rather than surface hardness. • The link plate holes are ball drifted. This process involves pressing a steel ball through the hole of the link plate. The steel ball is slightly larger than the diameter of the hole, which creates residual compressive stress.
