Product Introduction

Printing press bearings are mechanical components that support the rotating parts of a printing press, and are used to reduce friction and ensure the smooth operation of the printing press.

 

 

Product Features

High Wear Resistance: Printing press bearings are forged from GCr15SiMn steel with a PVD coating and nitriding treatment, resulting in a 40% longer wear life than ordinary bearings and minimal wear even after 8000 hours of continuous operation.

 

Corrosion Resistance: Resistant to ink and solvent corrosion, they will not rust even after prolonged contact with wet ink.

 

Sealed Design: Printing press bearings are equipped with double-lip fluororubber and stainless steel covers, achieving an IP66 protection rating, effectively isolating ink and dust.

 

Customizable: Bearings and surface coatings can be customized according to drawings, samples, or equipment dimensions.

 

Wide Applicability: Compatible with Heidelberg, Roland, and various high-speed roll and flatbed printing presses, meeting the needs of various printing materials and operating conditions.
