Lambda Lube-Free Chains

All of our Lambda Lube-Free chains can be divided into four different groups as well: Nickel-Plated Drive Lambda Lube Free Chains, RS Drive Lambda Lube-Free Chains, BS/DIN Drive Lambda Chains and conveyor Lambda chains. Nickel Plated single strand drive lambda chains and double strand drive lambda chains are great for applications that have a very high heat along with mildly corrosive environments.

Anti-Corrosive/Heat Resistant Chains

UST also supplies a wide range of anti-corrosive/heat resistant chains that are great for a number of different applications. These chains can be divided into Neptune brand chains, Nickel-Plated chains, stainless steel chain and poly-steel chains. Neptune chains are resistant to corrosion when they are exposed to harsh outdoor environment such as seawater. While stainless steel chains are great for applications where corrosion resistance is needed in addition to being able to support a large load capacity.

Theses specialty chains are designed with specific applications in mind which range from energy series chains, ultra-miniature chains, bearing bush chains, automatic tool changers chains, free flow chains, top chains, cableveyors, FX chain, Rollerless chain, Wrench Chain, Laminated Block chain and agriculture chains.

There are seven different styles of standard attachment chains: Single pitch attachment chains, Double Pitch Attachment Chain, Hollow Pin chain, Lambda Lube-Free Attachment chains, Curved Attachment Chains, Plastic Sleeve chains, BS/DIN Chain Series. On the other side of things, specialty attachment chains are divided into four categories: Crossrod Conveyor Chain, Live Tublar Roller Chain, Agriculture Attachment Chain, and Stock Specialty Attachment Chain.
