Applications

Steel Rolling Mill Motors
For compatible DC drives in rolling stands and related material-handling equipment, replacement brushes must match the motor's specified grade and dimensions. Inspect the brush holders and commutator during maintenance.

Crane and Hoisting Motors
D374N brushes may be considered for brushed DC motors used in compatible crane, lifting and hoisting systems. Confirm the original brush specification and connection details before replacement.

Industrial DC Generators
DC generators use brush-and-commutator assemblies for electrical current transfer. Replacement work should include checking brush dimensions, specified grade and commutator condition.

Cement Plants and Power Stations
Maintenance teams may require brushes for compatible DC motors or generators in auxiliary drive systems. Identify the actual motor model and original brush specification before confirming suitability.

Motor Repair and Spare-Parts Supply
Repair workshops and distributors can use the listed sizes as a starting point for identifying replacement parts. Original markings, drawings or physical samples help reduce specification errors.

OEM Supply and Replacement Matching

PUTAI supplies motor-related products and supports OEM manufacturing and customized industrial requirements. For D374N carbon brushes, the supply process should begin with confirming the required product specification and the intended application.

For Motor OEMs and Equipment Manufacturers
OEM buyers may require brush specifications to be aligned with a motor design, production drawing or approved bill of materials. Relevant information includes:
Motor model and design documentation.
Required brush grade and material specification.
Confirmed dimensions and tolerances.
Lead, terminal or connection details, where applicable.
Required quantity and delivery configuration.
Inspection or documentation requirements defined for the order.
Production or project-specific requirements should be reviewed against the approved technical documentation and actual manufacturing capabilities before acceptance.

For Industrial Distributors and Spare-Parts Suppliers
Distributors serving motor repair shops, industrial plants and maintenance contractors may need repeat orders across several brush sizes. To reduce part-identification errors, provide the original part number, brush marking, confirmed dimensions and any available drawing or photograph.
For recurring orders, keeping a consistent specification and part reference helps align subsequent purchases with the previously approved item. Stocking arrangements, minimum order quantities, packaging and lead times must be confirmed for the specific order rather than assumed.

For Maintenance Teams and Repair Workshops
When replacing worn brushes, provide the motor manufacturer and model, nameplate details where available, and the marking or part number on the original brush. If documentation is missing, clear photographs and a physical sample can help establish the required configuration.
Measurements should be taken from the original part where possible. If the brush is severely worn, its original dimensions may not be recoverable from the worn surface alone; an approved drawing or spare reference is preferable.

Manufacturing Capability

PUTAI's published company profile lists a 200,000 m² factory area, more than 120 employees, 18 technical engineers, RMB 80 million in fixed assets and over 25 years of motor-industry experience. These figures describe the company's overall manufacturing resources, not a dedicated D374N carbon-brush production line.

Quality Documentation and Inspection

Depending on actual availability and order requirements, relevant documents may include technical drawings, material records and dimensional inspection results. Confirm the applicable documents before ordering; company-level certificates do not automatically verify a specific carbon-brush grade or batch.
