Inverted tooth chain RENOLD HDL 585 - 3/4" x 85 mm - 108 links

The HDL 585 inverted tooth chain is a special type of chain designed for heavy loads (HDL = Heavy Duty Link). It has a pitch of p=3/4" (19.05 mm) and a nominal width of bn=85 mm.

Unlike standard roller chains, which engage the sprocket via rollers, inverted tooth chains feature precise teeth on the underside of the link that mesh with the corresponding profile on the sprockets, ensuring precise torque transmission without slippage.

Compared to standard roller chains, HDL inverted tooth chains exhibit significantly higher strength and wear resistance, making them primarily suitable for applications where operational reliability is required.

Due to their design, HDL chains feature lower noise levels and are more compact, making them advantageous for use where equipment noise is undesirable or for smaller installation spaces.

Most commonly, these chains find applications in the automotive industry, e.g., as timing mechanisms, as well as in mechanical engineering on machine tools or presses, or in power generation equipment.
