Description
Ensure smooth mechanical clearance adjustment and prevent internal air leakage within your heavy commercial vehicle braking system with the genuine FAG Air Disc Brake Adjuster Bearing & Flange Assembly. Engineered specifically for high-stress air disc brake calipers, this precision-machined assembly combines a high-load needle/thrust bearing with a robust mounting flange. Worn adjuster bearings cause binding internal mechanisms, erratic clearance adjustment, and dangerous brake fade, while cracked flanges lead to pneumatic pressure loss. This professional-grade FAG assembly solves those failures directly. It utilizes high-purity bearing steel, precision aluminum-alloy or reinforced steel flanges, and advanced sealing interfaces to deliver rigid shaft alignment, frictionless rotational support, and long-lasting durability in demanding transport fleets.
Technical Parameters
| Category | Specifications & Technical Details |
| High-Rigidity Precision Adjuster Bearing Support | We integrate deeply heat-treated high-purity needle and thrust bearings inside the adjuster. As a result, they withstand combined axial and radial loads during high-frequency brake adjustment. Moreover, they eliminate internal shaft wobble. |
| High-Strength Corrosion-Resistant Mounting Flange | We manufacture the flange from high-pressure forged aluminum alloy or heavy-duty steel. Consequently, it fits tightly against the caliper housing. Notably, it never deforms under +200°C high temperature. |
| Integrated Airtight Sealing & O-Ring Interface | We equip the assembly with specialty high-pressure, oil-resistant rubber seals and O-ring grooves. Therefore, they completely block external moisture, mud, and brake dust from entering the internal transmission mechanism. |
| Micron-Level Concentricity & Shaft Alignment Tolerance | We follow strict Schaeffler manufacturing standards. As a result, the adjuster shaft and internal transmission gears achieve perfect concentric fit. Meanwhile, this eliminates mechanical binding. |
| Industrial Moisture-Resistant Protective Packaging | We apply long-life anti-rust oil and individual vacuum sealing before shipment. Consequently, this ensures zero corrosion and zero contamination during international bulk wholesale, warehousing, and transport. |
Applicable Car Brands & Models
Common warning symptoms include:
Stuck or Inoperative Adjuster Mechanism: The internal clearance fails to adjust automatically, resulting in excessive pedal travel or dragging brakes.
Air Leaks Around the Flange: Audible hissing or bubbling near the adjuster mounting plate during brake application.
Visible Grease Seepage or Corrosion: Heavy rust buildup or oil leaking from the flange mating surface due to compromised seals.
The bearing and flange are factory-machined as a matched unit to ensure exact shaft alignment and airtight sealing. Replacing them as an integrated assembly prevents misalignment, premature bearing wear, and dangerous pneumatic leaks.
Yes. Professional installation requires clean workshop conditions, precision press tools, and torque wrenches to secure the flange mounting bolts according to the axle manufacturer’s exact specifications.
Each unit is treated with anti-corrosion oil, sealed in a heavy-duty moisture-proof protective bag, and packed inside a reinforced industrial corrugated box with custom inserts to guarantee safe global wholesale transit.
