NTB-50-4 固體鑲嵌潤滑軸承 / Solid-lubricant-Embedded
NTB-50-4 Series
Substrate characteristics
NTB-50-4 inlaid solid lubricating bearings with cast iron as the base material, according to the use conditions by a certain percentage of its working surface and fill cavities machined solid lubricant, cast iron alloy provides a high load carrying capacity and the solid lubricant can form a low friction, showing a low speed under high load conditions its excellent self-lubricating properties.
Technical Parameters

NTB-50-4 self-lubricating material provides a solution that combines abrasion resistance and mechanical strength and self-lubricating properties of cast iron solid lubricant, so that in the process without the use of oil or less maintenance; particularly suitable for high load so if the car at low speed and intermittent swing working conditions covering die, metal stamping dies, injection molding machinery and metallurgical equipment.
