The 6805 plastic deep groove ball bearing is made of high-performance engineering polymers such as POM or PEEK, featuring complete rust resistance and excellent chemical resistance. It is lightweight, electrically insulating, capable of operating dry or with minimal lubrication, and is an ideal choice for food processing, chemical treatment, medical equipment and humid environments.
Product Specifications & Design Details
Bearing Type: Single-row, deep groove ball bearing, designed to radial and light axial loads.
Dimensiones (Metric Standard):
Bore Diameter (d): 25 milímetros
Outer Diameter (D): 37 milímetros
Width (B): 7 milímetros
Total Corrosion & Chemical Resistance
This is the primary advantage. The 6805 plastic bearing is completely impervious to rust and highly resistant to a wide range of aggressive chemicals, salts, solvents, and alkalis that would rapidly destroy steel bearings. It is ideal for constant washdowns or exposure to corrosive fluids.
Ligero & Electrically Insulating
Significantly lighter than metal, reducing inertial mass in rotating assemblies. Its non-conductive nature makes it perfect for applications requiring electrical isolation to prevent stray currents or arcing damage.
Clean, Low-Maintenance Operation
Non-magnetic and non-porous, it resists debris adhesion and is easy to clean. It operates quietly with low friction and can run without oil or grease, making it indispensable in food, pharmaceutical, and cleanroom settings where contamination is unacceptable.
Excellent Performance in Wet Environments
Unlike steel, polymers do not corrode when exposed to water, steam, or high humidity. This ensures reliable performance in marine applications, water treatment plants, and food processing machinery.
Food & Beverage Processing
Conveyor rollers, bottling line guides, mixer bearings, and packaging equipment subject to frequent high-pressure washdowns with cleaning agents.
Chemical & Pharmaceutical Manufacturing
Pumps, agitators, and valve linkages exposed to corrosive chemicals or where product purity is critical.
Medical & Laboratory Equipment
Imaging devices, fluid handling pumps, and diagnostic equipment where cleanliness, quiet operation, and non-magnetic properties are required.
Water Treatment & Marine
Submerged or splash-zone applications in pumps, filters, and control mechanisms.
Electrical & Semiconductor
Applications requiring electrical insulation, such as in motor housings or material handling in PCB production.
