Original Press Release:
Bigger Cam Follower Sizes for Greater Load and Life Capabilities with a Repeatability of 30 Arc Seconds is Now Available from Sankyo America
Sankyo America's Alpha Series is a low profile indexing drive with input and output characteristics that meet, or exceed most common indexing requirements. The Alpha Series has the widest range of standard index periods, # of stops, and sizes available today. The oversized cam followers are custom manufactured to fit our cam, which offers extremely rigid, smooth and accurate indexing. Standard accuracy on any Alpha Series is ±30 arc seconds with higher accuracies available upon request. The double row of tapered roller bearings supports our turret, while the cast iron housing offers a solid and accurate system over greater temperature ranges. The custom made seals has 5-8 times more surface area, which means the oil stays in and contaminants stay out. The standard machined through hole and stationary center post offers the assembler more options when considering tooling and wiring. A full line of "easy to use" torque limiters are available to protect your investment. The Alpha Series has been designed to meet the most rigorous cycle on demand applications. The extra large cam followers offer greater load and life capabilities. This precision indexer (±30 arc seconds) has the widest range of sizes, stops and index periods available today. Our enhanced sealing system keeps the oil in and contaminants out!
