Frequently Asked Questions
Q: What does the BR A27327-121 brush set include and what is its material?
A: The BR A27327-121 is a set of 4 carbon-graphite brushes designed for Barrett electric lift truck drive motors. Carbon-graphite composition provides good electrical conductivity and moderate wear resistance for 24VDC motor systems.
Q: What voltage systems is the BR A27327-121 compatible with?
A: The BR A27327-121 brush set is compatible with 24VDC drive motor systems. Do not use this brush set on 36VDC or 48VDC systems as brush grade and wear rate differ across voltage classes. Verify your equipment voltage before ordering.
Q: Why is the BR A27327-121 sold as a complete set of 4 brushes?
A: Replacing all 4 brushes simultaneously ensures even wear, balanced contact pressure, and optimal motor performance. Mixing old and new brushes causes uneven commutator wear, arcing, and reduced motor efficiency. Always replace brushes as a complete set.
Q: What is the typical replacement interval for BR A27327-121 brushes?
A: Carbon-graphite brushes typically last 1500 to 3000 operating hours in 24VDC lift truck motors. Heavy duty or continuous operation reduces life. Monitor commutator condition and brush length. Replace the set when brushes wear to one-quarter inch or if arcing develops.
