INTRODUCTION

The offset url chain is developed with higher abrasion, effect, and corrosion resistance to satisfy the application needs in sugar generating business. Its facet plates are bended but with paralleled finishes. Each hot bending and cold bending strategies can be applied for facet plate processing. The adoption of sophisticated bending die, coupled with improved top quality inspection, tends to make positive the bending of facet plates will come with no cracks. Therefore, the offset sidebar chain will not split effortlessly below heavy load conditions.
Manufactured making use of stainless steel and alloy steel components, our offset hyperlink chain for sugar industry delivers minimum tensile energy possibilities among 250 and 900KN, and rated doing work load alternatives from18 to 85KN.
