The Bendix ADB22X, an air disc brake on Class 6 to 8 commercial vehicle wheel-ends, now includes next generation improvements designed to increase uptime and lower operating costs, according to the company.
"Thanks to a new adjustment mechanism that's engineered for increased vibration robustness while improving the running clearance between the friction and rotor, the new ADB22X improves pad life and reduces residual brake drag, which results in extended service life," said Keith McComsey, director of marketing and customer solutions, Wheel-End, at Bendix Spicer Foundation Brake LLC. "The adjustment mechanism is a proven piece of technology that we originally implemented with the trailer-specific Bendix ADB22X-LT, and its success, combined with positive feedback from fleets using the trailer air disc brake, made it an obvious choice for building on the success of the ADB22X family."
The ADB22X is also now coupled with Bendix’s longest-life air disc brake (ADB) friction – the Bendix BX276 air disc brake pad – without sacrificing any performance, according to the company. The BX276 model, which includes an additional two millimeters of thickness compared with its predecessor (the BX275), delivers an 8 percent increase in wearable volume. In developing the BX276, Bendix also reformulated the friction to achieve an improved wear rate, resulting in a pad with up to 40 percent reduction in wear rate than its predecessor.
A number of North American truck manufacturers have already made the optimized brake available, while the remainder expect to do so by the end of 2019.
Since 2005, Bendix has produced nearly 3 million ADB22X units, accounting for approximately 85 percent of the air-disc-braked wheel-ends on North American commercial vehicles. The company’s production numbers reflect an ever-increasing demand for air disc brakes in the commercial vehicle industry. Worldwide, Bendix and its parent company, Knorr-Bremse, are the clear global leader in air disc brake production at over 40 million and counting.
