Gear Racks made of plastic - die cast
Application area
Model making, laboratory technology, mechanical engineering, high-precision mechanics
Product specification
Low-price gear racks for low to medium load, if low weight and/or high chemical resistance is required.
Square gear racks made of plastic.
Module 0.5 / 0.7 / 1.0 / 1.5 / 2.0 (module teeth according to DIN 867).
Good mechanical strength properties.
Good coefficient of sliding friction.
High stiffness and hardness.
Good temperature resistance.
Not fire-proof and hydrolysis-resistant.
With high hardness and low friction coefficient they can be used in various set-ups, even under water.
Because of the material used, these gear racks are slightly arc-shaped. The gear rack has to be straightened by corresponding fastening material when mounting.
Chemically resistant to dilute alkalis, hydrocarbons, saturated oils, fats and aromatic compounds. Limited resistance to ketones, esters and hot water / suds.
