Frequently Asked Questions
Q: What are the dimensions and specifications of the CR 20252-001 motor brush?
A: The CR 20252-001 is a Grade A carbon-graphite motor brush with dimensions of 16 mm x 25 mm. It is constructed to ASTM C587 specification and rated for 48VDC insulation, matching Crown electric lift truck motor system voltage. The brush is engineered for continuous duty cycle operation at 100% rated capacity in motor applications.
Q: What Crown electric lift truck models use the CR 20252-001 brush?
A: The CR 20252-001 is compatible with selected Crown electric lift truck motor assemblies. Verify that the 16 mm x 25 mm dimensions match your equipment motor bore and brush holder before ordering. Cross-reference part numbers 020252-001 and 20252-1 indicate equivalent OEM fitment.
Q: How does the Grade A carbon-graphite material affect brush performance?
A: Grade A carbon-graphite construction provides optimal commutator contact, electrical conductivity, and wear resistance in continuous duty motor applications. This material composition minimizes arcing and brush noise while delivering consistent performance under sustained 48VDC load cycles typical of lift truck motors.
Q: What cross-reference part numbers are equivalent to CR 20252-001?
A: The CR 20252-001 cross-references to 020252-001 and 20252-1. These are OEM equivalent part numbers for the same carbon-graphite motor brush assembly. Verify compatibility with your specific motor assembly before ordering.
Q: What is the typical service life of this motor brush in lift truck applications?
A: Service life depends on duty cycle intensity, commutator condition, and brush holder wear. Grade A carbon-graphite brushes in continuous duty applications typically perform for 1,000 to 2,000 operating hours before replacement becomes necessary. Inspect periodically for wear and replace when brush length approaches minimum specification.
