Electrical Insulation Protection: Ceramic coating blocks shaft currents to prevent pitting, fluting, and premature bearing failure.
Extended Maintenance Intervals: Reduces vibration and noise while protecting lubricant from degradation caused by electrical discharge.
Direct Replacement Capability: Can replace non-insulated NU bearings without changing basic envelope dimensions or mounting.
Multiple Voltage Options: Available with standard (1,000V), enhanced (2,000V), or high-voltage (3,000V) DC insulation classes.
Flexible Insulation Configurations: Offers outer-ring or inner-ring insulation to suit specific current path and capacitance requirements.
High Radial Load Capacity: Single-row NU design supports high radial loads while allowing axial displacement for free-end positions.
Customization Options: Available for full customization, minor customization, and customization from samples or designs.
Diverse Cage Materials: Options include pressed steel, machined brass, or engineering polymer based on size and application.

Financial creditThe supplier has consistent financial data over the last three years, showing stable financial capacity.
R&D capabilityThe supplier does not have research and development capability with SDK availability.
Customization capabilityThe supplier offers full customization, including from samples and designs, indicating strong flexibility in product customization.
Product Q&A
Q:Does the ceramic coating change the bearing dimensions?
A:
The insulation layer is engineered so the finished bearing retains the nominal envelope dimensions of the corresponding standard NU bearing. Final tolerances must be confirmed for the selected coating and fit.
Q:Should I choose outer-ring or inner-ring insulation?
A:
Outer-ring insulation is commonly selected for housing-side isolation. Inner-ring insulation may be preferred for shaft-side isolation or when lower capacitance is required. The current path and mounting arrangement should be reviewed.
Q:Can an NU bearing carry axial load?
A:
The NU design is primarily a radial, non-locating bearing. It permits axial displacement in both directions and normally requires a separate locating bearing elsewhere in the arrangement.
Q:Can C3 or C4 clearance be supplied?
A:
Yes, subject to model availability and engineering confirmation. Motor temperature, interference fits and operating speed should be considered before selecting clearance.
Q:What information is required for a quotation?
A:
Required details include NU bearing base model, quantity, insulation position, operating voltage, minimum electrical resistance, radial clearance, preferred cage material, motor speed, radial load, operating temperature, shaft and housing fits, lubrication method, service environment, and required test reports.
