Product Description

Raydafon “H” Class Mill Chain is a robust, serviceable chain designed initially for heavy drives and transfers conveyor purposes in sawmills and the paper and pulp industry. “H” Class Chain has proven itself for numerous other industrial applications, especially for medium-duty in abrasive atmospheres where the heavy, rugged chain is required. The sidebars of the “H” Class links are reinforced with wearing shoes which strengthen and stiffen the links when it is operated in troughs or over floors and runways.

Pinholes are precision cored to assure accurate pitch sizes, ranging from 2.308 to 4.000 inches. “H” Class Chain is available in both riveted and cottered construction. T-head pins engage two lugs cast on the links’ sidebars. This configuration prohibits pin rotation during chain operation, eliminating abrasive wear and pitch elongation.

Raydafon “H” Class Mill Chain conforms to the manufacturer’s standards and is completely in- interchangeable with chains of other manufacturers. “H” Class Chain is available in Allied-Locke Promal with tensile ranges of 9,450 to 40,500 pounds.

“H” Class Chain may operate in two directions. As a drive chain, it travels in the direction of the closed barrel; for elevator or conveyor applications, it should travel toward the open ends of the links.

Brutal or cast steel sprockets are available to accommodate every “H” Class pitch size. A wide assortment of attachments is also available for varied chain applications.

Chains and Sprockets

Chains and sprockets are mainly used in all applications such as transportation, machinery and other motor applications.
Chain and sprockets are maintained with grease and oil spray to provide smoother and better operation.
It makes the wheels run as the motor rotates and is considered as Rotation Per Minute (RPM).

Chains and sprockets are mainly used in the transport industry and machine building industry to rotate wheels by means of motors or engines. These chains and sprockets both help the wheelbase to run fast according to the engine speed. The chain hangs between the motor and the sprocket, the motor turns the sprocket and the chain is connected to the sprocket teeth, which can turn simultaneously with the motor wheel, thus making the vehicle or machine run smoothly. Raydafon is one of the leading manufacturers and suppliers in China. We can offer various high-quality chains and sprockets for sale.
