094-10300 - Cleveland OEM Brake Nut

094-10300 – Cleveland OEM Brake Nut

Available now on the Airparts.aero Marketplace.

Overview

The Cleveland 094-10300 is a genuine Original Equipment Manufacturer (OEM), self-locking hexagon nut, engineered specifically for securing components in Cleveland's world-renowned aircraft wheel and brake assemblies. This nut is a prevailing torque type, utilizing a nylon insert to provide a reliable locking action that resists loosening under the severe vibration and stress experienced during ground operations, taxiing, and braking. As the OEM-specified part, it is manufactured to the exact standards required by Cleveland for maintaining the integrity and safety of their certified braking systems.

Key Features

• Vibration-Resistant Locking: Features a captive nylon (polyamide) locking collar. As a bolt is threaded through, the nylon insert is elastically deformed, creating a powerful frictional grip on the threads that provides prevailing torque and prevents loosening without the need for secondary locking devices.
• OEM Specification: As the genuine part specified by Cleveland Wheels & Brakes (a division of Parker Hannifin), it guarantees the correct material strength, thread class, and locking performance required for their brake assemblies.
• Durable Steel Construction: Fabricated from a high-quality carbon steel alloy, providing the necessary tensile strength to achieve proper clamping force on critical brake components like caliper bolts and torque plate fasteners.
• Corrosion-Resistant Plating: Plated with a durable cadmium finish to provide robust protection against corrosion from moisture, de-icing fluids, and other environmental factors.
• Direct Interchangeability: This nut is dimensionally and functionally equivalent to the military standard MS21044N4, making it a familiar and standardized component for maintenance professionals.

Aircraft Compatibility

The Cleveland 094-10300 is the specified locknut for thousands of aircraft across the general aviation fleet that utilize Cleveland wheels and brakes. Its use is determined by the specific brake assembly part number.

• Common Aircraft Manufacturers:
  • Cessna
  • Piper
  • Beechcraft
  • Mooney
  • Cirrus
  • And countless other certified and experimental aircraft.
• Common Applications:
  • Securing brake caliper halves.
  • Fastening the brake torque plate to the landing gear axle flange.
  • Mounting other components within the wheel and brake assembly.

Applications

The 094-10300 is a flight-critical fastener for ensuring brake system integrity:

• Brake Assembly & Overhaul: The specified nut for assembling and overhauling Cleveland brake calipers and mounting the torque plate.
• Vibration-Proof Fastening: Provides a secure joint that will not loosen, ensuring that brake pads remain aligned and that the caliper maintains its correct position relative to the brake disc.

Why Choose 094-10300?

The aircraft braking system is subjected to immense force, vibration, and temperature changes. The failure of a fastener within this system can lead to a complete loss of braking authority. The Cleveland 094-10300 is the nut specified and certified by the brake system manufacturer to handle these specific loads. Using the genuine OEM part ensures you are installing a fastener with a known quality, certified locking performance, and the correct material properties, which is essential for a safe and airworthy repair.

The 094-10300 nut's prevailing torque feature is a critical safety aspect. The nylon collar's inner diameter is intentionally smaller than the major diameter of the bolt's threads. As the nut is tightened, the bolt must cut or form its own thread into the nylon. This tight interference creates a 360-degree frictional grip that is independent of the seating torque. This means the nut resists rotation even if the initial clamping force is slightly reduced due to component settling or thermal cycling, providing a stable and secure connection that a simple nut and lock washer cannot replicate in the high-vibration environment of a landing gear assembly.

Note: This is a flight-critical component. It must be tightened using a calibrated torque wrench to the value specified in the applicable aircraft or component maintenance manual. While reusable, the nut must be discarded if its prevailing torque falls below the minimum specified value (i.e., if it can be run down the bolt threads by hand), as this indicates the nylon locking element has worn out.
