PTH insulation coated bearings are produced by precisely coating the outer ring and side of the bearing with polymer resin with excellent insulation effect several times. Insulation-coated bearings prevent electrical erosion of bearings caused by motor axial current, increasing bearing life and reducing maintenance costs for customers.
1. Specifications of supplied products
• N210-E-M1-C3-J20A ~ N220-E-M1-C3-J20A
• NU1008-M1-C3-J20A ~ NU1038-M1-C3-J20A
• NU208-E-M1-C3-J20A ~ NU234-E-M1-C3-J20A
• NU308-E-M1-C3-J20A ~ NU330-E-M1-C3-J20A
2. Characteristics of bearings
• A bearing with multiple rollers inserted between the inner and outer rings of the
bearing.
• It has a wider contact area than ball bearings, so it has high radial load carrying
capacity.
3. Excellence of Insulation Coating
• Stable withstand voltage of 1000v
• Excellent abrasion resistance with 4H surface hardness
• Provides slimness to the coating surface to prevent deposition of impurities
4. Perfect compatibility
• Insulated bearings have the same dimensions and load capacity as non-insulated
bearings, so they have perfect compatibility.
5. Application
• Electric motors and generator motors
• Variable frequency motor
• Traction motor
• Wind power motors
• Industrial pumps
