BIRS Machine & Supply – Your Source for Creepage Bands / Transband
Need reliable creepage protection for electric motors?
BIRS Machine & Supply supplies high-quality PTFE creepage bands (including Transband-style seamless bands) for motor repair and rebuild work.
What is a Creepage Band?
A seamless PTFE (Teflon) insulating band applied to the outer end of the commutator on a motor rotor/armature. It blocks surface current tracking (creepage) between the live commutator bars and the grounded rotor core or shaft.
Common Applications:
• DC motors & generators
• Traction motors (mining, rail, industrial)
• Large industrial motors
• Commutator end insulation during armature rewinds
• High-voltage / high-temperature motor environments
• Anywhere tracking resistance and dielectric strength are critical
PTFE creepage bands offer excellent dielectric strength, chemical resistance, low friction, and high-temperature performance — exactly what motor shops need for lasting repairs.
