8-Hole Brake Drum with 6.5" Bolt Circle for Secure Wheel Fitment
To keep the wheel securely in place, this semi trailer brake drum features an 8-hole design with a 6.5-inch bolt circle. The bolt pattern helps keep the wheel centered during installation and matches typical trailer axle configurations. Accurate alignment minimizes errors and facilitates installation.
Gray Cast Iron Brake Drum Construction for Heat Resistance and Stable Braking
The gray cast iron used to make this brake drum is known for its good heat dissipation. Friction causes heat to accumulate inside the drum during braking. This heat is dispersed uniformly and released more quickly by gray cast iron. It reduces the risk of brake fade, which occurs when the brakes lose effectiveness after prolonged use. Stable temperature regulation ensures dependable, powerful braking.
Pre-Assembled Brake Hub Drum with 7/16-20 UNF Studs for Easy Installation
This semi trailer brake drum comes pre-assembled with essential parts already in place. This design minimizes installation work and saves time. Installing internal components individually is not necessary for users. The 7/16-20 UNF wheel studs provide a sturdy, secure mounting point. These studs reduce the risk of loose fittings and encourage proper tightening.
Strong Electric Brake Drum Designed for Long Service Life Over 30000 km
Designed for forever use, this brake drum has a service life of more than 30,000 kilometers. The sturdy construction withstands heavy loads, road impacts, and frequent braking without obvious damage. Solid construction and sturdy materials contribute to the drum’s long-term dependability. As a result, fewer part replacements are required.
