Transmission Chain

At Renold, we design and manufacture high performance transmission chain which offers outstanding levels of wear and fatigue resistance, ensuring maximum reliability in some of the most demanding industrial applications. With a Renold chain you can be confident of reducing downtime and increasing productivity. 

We offer two chain varieties: Standard Chain, which combines a wide-waisted plate shape for extra fatigue resistance with an end-softened, spin riveted pin for easy installation, and Solutions Chain, which has the same features but is designed to tackle the challenges of corrosion, abrasion and high shock load. 

We also offer several ‘specials’ for specific industries. These include:

• Small and large pitch (4mm up to 4 inch) chain
• Adapted Transmission Chain
• Hollow bearing pin chain
• Nickel Plated Chain
• Zinc Plated Chain
• Extended pitch chain  
• Sidebow chain
• Cranked link chain
• Bush chain
• Oilfield Chain

Conveyor Chain

Extensive design experience and flexible manufacturing techniques enable Renold to produce conveyors chains for a wide range of applications across many different industries. In fact, we can adapt our chain to meet the most demanding requirements. Typical applications include:

• Bakery conveyors
• Crawler cranes
• Escalator steps
• Heavy duty conveying
• Oilfield applications
• Road pavers
• Sugar mill conveying
• Waste water treatment

All of our chains can be manufactured to various international standards, including BS and ISO. To find out more about how our chains are made, please visit our website or click on the image to the right. 

Leaf Chain

Used in a range of material handling applications and in many major civil engineering projects, Renold leaf chains offer exceptional fatigue strength, a high level of wear resistance and an extremely long service life. They feature link plates made from a special steel that can withstand shock loads, bearing pins that have excellent resistance to bending, and inner link plates that are manufactured to the closest tolerances in order to minimise friction and maximise efficiency.

Smartlink

Smartlink™ is a system that allows you to monitor chain performance as it travels through your machine. A tiny microprocessor is attached to the side plate of a chain link and sends stress load information to a handheld receiver. If the stress-load conditions exceed the pre-determined limit values, the receiver will warn the operator so that an inspection can be made. More advanced chain data can also be transferred from the receiver to a Windows-based PC for in-depth analysis. Find out more about Smartlink™ and its safety benefits by visiting Renold online.

Sprag Clutch Freewheels

A sprag clutch is a freewheel device that has an inner race and an outer race, either of which can be the input or output member. The input member can be configured to drive the output member in the chosen direction whilst permitting the output member to over-run in the same direction. Generally speaking, a sprag clutch is able to transmit greater torque than other types of freewheel device (size for size). The three basic applications are:

• Overrunning
• Indexing
• Backstopping

Discover our range of standard sprag clutch freewheels by visiting Renold online. 

Trapped Roller Freewheels

A trapped roller freewheel consists of a cylindrical outer race, an inner race with ramps and individually sprung rollers. The springs ensure that the rollers are held in contact with the outer race and inner race ramp, enabling instantaneous torque transmission. Trapped roller freewheels have three basic applications:

• Overrunning
• Backstopping
• Indexing
