Overview of SS20B-U1 Stainless Steel Roller Chain with U Type Attachment
The SS20B-U1 Stainless Steel Roller Chain with U Type Attachment is a high-strength chain designed for heavy duty applications. This chain is made of durable stainless steel, ensuring longevity and corrosion resistance. The standard pitch of the roller chain is 1.5 inches, and the width is 0.5 inches; the U-joint is 1 inch wide and 1.5 inches high.
This roller chain with U-joint is commonly used in conveyor systems, packaging machinery, and other industrial applications requiring reliable and durable chains. Its stainless steel construction makes it suitable for harsh environments such as the food and beverage industry, chemical plants, and outdoor applications.
With its high strength and durability, the SS20B-U1 Stainless Steel Roller Chain with U Type Attachment is an excellent choice for heavy-duty applications.
Structure of SS20B-U1 Stainless Steel Roller Chain with U Type Attachment
The chain section of SS20B-U1 Stainless Steel Roller Chain with U Type Attachment is an improved version of the standard roller chain, ensuring basic transmission function and strength. It is typically made of 304 or 316 stainless steel, with stainless steel pins, bushings, and gaskets between the chain links to ensure corrosion resistance. The U-shaped cover, also made of stainless steel, is fixed to the chain pins or gaskets. It provides a flat bearing or conveying surface for the chain, helping to stabilize the material transport. The U-shaped structure better encloses and stabilizes the transported material.
