Material Specifications

The document specifies the materials used for the components of the HS-820 series plastic chains. Plate materials include POM-DP and POM-F, while pins are made from cold rolled austenitic stainless steel. These materials ensure durability and corrosion resistance suitable for various industrial applications.

Dimensions and Physical Parameters

The chains come in various sizes with key dimensions provided in millimeters and inches. For example, the radius and reverse radius are consistently 50 mm (1.97 inches) across several models. Weight varies by model, ranging from approximately 0.46 kg/m to 1.47 kg/m, indicating different chain sizes and strengths.

HS-820 Series Variants

The HS-820 series includes multiple variants such as K250, K325, K350, K400, K450, K600, and K750, as well as mini versions like HS-820 mini-K118 and mini-K126. These variants differ in dimensions such as width (W), pitch (P), and height (H), accommodating different load requirements and sprocket sizes.

Load Capacities and Working Loads

Working loads are specified at 21℃, with values typically around 1230 N (approximately 276 lbs) for many models. This indicates the maximum tensile load the chains can safely handle under standard temperature conditions.

Dimensional Details

Key dimensions include pitch (P), module (M), width (W), height (H), thickness (T), length (L), and other parameters such as E and RD, which relate to chain geometry and fit with sprockets. For example, pitch values are around 38.1 mm for mini series and up to 44.5 mm for larger chains.

Applications and Compatibility

The chains are designed for straight running applications and are compatible with specific sprockets such as HS-820 K250 through K750. The document implies suitability for various industrial conveyor and transmission systems requiring plastic chains with stainless steel pins.
