Description
Drive roller chains have a wide variety of sizes, which start with a pitch of 8 mm and end with a pitch of 63.5 mm. These chains are designed to drive the gears and gears. The rollers that are on the rollers provide a reduction in friction in the nodes of the connection units.
These chains are specially marked, which includes a designation of the type of chain, its pitch, maximum load that will destroy the chain (tension) and marking of the type of execution.
Type of chain – PR. This parameter indicates that the circuit is drive. A step can consist of either an integer or a fraction. The load of destruction is indicated in kilonewtons. Execution is a parameter that may not be in the circuit designation. It defines the coating of the chain with various metals and the method of finishing the chain.
