Brush carbon brush 55 5x8x20 No name model Czę001173

Carbon brush 55 5x8x20 is a rectangular replacement electrode intended for use in electric motors and power tools that require a brush with dimensions 5 x 8 x 20 mm and the designation "55". Supplied under the No name brand, this carbon brush is designed for routine maintenance and repair of compatible rotating electrical machines where a compact, rectangular carbon contact is required. The product is intended to restore electrical contact between the commutator or slip ring and the stationary conductor assembly.

Advantages

This carbon brush offers a compact rectangular shape and standardized dimensions that simplify replacement in devices designed for 5 x 8 x 20 mm brushes. The graphite composition provides reliable electrical conductivity and helps reduce wear on the commutator when properly matched to the motor. The standardized form factor supports straightforward installation and predictable contact performance during normal operating conditions.

Suitable for

• Replacement in small electric motors and power tools that accept 5 x 8 x 20 mm rectangular brushes
• Maintenance and repair tasks on portable power equipment and household appliances with compatible brush holders
• Service workshops performing routine brush inspection and swap-outs to maintain motor performance

Key specifications

• Brush dimensions: 5 x 8 x 20 mm (rectangular)
• Designation: "55" style carbon brush
• Material: carbon/graphite contact material suitable for commutator use
• Form factor: rectangular block designed for brush holders that accept 5x8x20 mm brushes
• Typical applications: commutator and slip-ring contacts in small motors and power tools

How to use

Turn off and disconnect the device from power before attempting replacement. Access the brush holder according to the equipment manufacturer's instructions, remove the worn brush and inspect the holder and commutator for excessive wear or contamination. Insert the new 5x8x20 carbon brush into the holder ensuring correct orientation and secure any retaining hardware or springs. Reassemble the device, reconnect power, and run the motor briefly under no-load conditions to verify stable contact and absence of abnormal noise or sparking.

Usage recommendations

Use this carbon brush only in compatible motors and tools that accept 5 x 8 x 20 mm rectangular brushes and the same brush style designation. Replace brushes in matched pairs when applicable, inspect commutator surfaces for grooves or heavy deposits, and clean or service the commutator if necessary to ensure even wear and optimal electrical contact.
