German AL20 coupling AL20 model AL20 price

AL20 coupling is a widely used coupling, also known as a jaw coupling, consisting of two metal jaw hubs and an elastomer. The two metal jaw hubs are generally made of 45 steel, but aluminum alloy is also used when load sensitivity is required. AL20 coupling manufacturing process: The spider coupling is machined by turning, milling, and broaching, followed by overall heat treatment to ensure sufficient mechanical strength. There is also a type of jaw hub on the market that is cast, allowing for mass production and eliminating machining losses. Therefore, in terms of price, it is lower than machined
