A grease seal, often called an oil or dirt seal, is a type of seal utilized to retain grease in a case or housing. Grease seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. Preventing harmful containments from entering machinery is another critical function of a grease seal. Oil and grease seals are available in numerous lip materials. Popular materials include felt, leather, urethane, nitrile, polyacrylate, ethylene-acrylic or polyacrylic, silicone, fluoro-elastomer, tetrafluoro-ethylene propylene and PTFE. Cleveland Grease Seals are intended for use in Cleveland Wheel Assemblies.

Although magnesium wheels and brakes are considerably lighter, magnesium is subject to corrosion and should not be used for amphibious operation. Only organic linings should be used on all brakes. All parts of the 500 x 5 size wheels and brakes for amphibians are constructed of anodized aluminum for water resistance (199-105). Their use is suggested if bearings are kept well greased. A reasonable service can be expected, but earlier bearing replacement should be anticipated. Alternatively, the use of  wheels and brakes with chrome plated bearings and brake disc and water drainage holes (199-105C) is recommended for best results in amphibious use. However, they are too costly for use on homebuilt aircraft.

CLEVELAND 199-105C TSO'd Wheel and Brake Assembly includes wheels with matching hydraulic chrome brake disks. Wheels with chrome brake discs are FAA-TSO approved under the original model number. 

Wheels come complete with bearings and wheel covers. Brake assembly has linings installed. Sold in pairs only. Best suited for amphibious operations.

MICHELIN® Aircraft Tyres is internationally recognized as the No.1 tire manufacturer in the world. The company provides bias tires, radial tires, and tubes for aviation customers around the world, in a range of applications including commercial and regional airlines, general aviation and military aviation. 

MICHELIN® AIRSTOP® Aircraft Tire Inner Tubes provide long-lasting, dependable performance you can rely on in just about any operating condition. Made from exclusive Michelin butyl compound they offer  extended air retention and can sustain temperatures as low as -50°C.  In addition, they are formed without a circumferential splice, resulting in fewer joints and a more uniform tubewall thickness after inflation for optimized reliability at a minimal weight.  AIRSTOP tubes are manufactured to exacting balance tolerances (without correction), which meet or exceed all industry standards. This eliminates the need to further balance the wheel assembly in order to compensate for balance irregularities in the tube. Tube lubricant is factory applied to the tube exterior for easier installation and to help minimize foldover after installation and inflation. Comply with Aerospace Standard AS50141. Available in different sizes. Please also refer to the attached documentation.

Product Features:

Advanced Butyl Material

Exclusive Michelin® butyl compound offers excellent resistance to diffusion for extended air retention and dependable performance. Michelin® AIRSTOP® tubes help provide the same high quality seal found in Michelin® AIR X® radial tires.

Circular Extrusion Manufacturing Process

A Michelin® exclusive, Michelin® AIRSTOP® tubes are formed without a circumferential splice, resulting in fewer joints and a more uniform tubewall thickness after inflation. This helps provide optimized reliability at a minimal weight.

Built-In Balance

All Michelin® AIRSTOP® tubes are manufactured to exacting balance tolerances (without correction), which meet or exceed all industry standards. This eliminates the need to further balance the wheel assembly in order to compensate for balance irregularities in the tube.

Easy Installation

Tube lubricant is factory applied to the tube exterior for easier installation and to help minimize foldover after installation and inflation. In addition, molded vent ridges help channel trapped air back to the valve stem for easy release.

Low Temperature Performance

Michelin® AIRSTOP® tubes are designed to perform in the extreme low operating temperature of minus 50o C, so you can confidently fly in cold weather with consistent, reliable performance.

High Quality Complies with Aerospace Standard AS50141.

AIRFRAMES ALASKA designs and manufactures ALASKAN BUSHWHEEL (ABI) wheels & brakes and tires made for flying and landing off-field in the most rugged backcountry conditions. ABI tires absorb the energy of rough landings, taking the brunt of the impact off the pilots, wheels, gear, and airframe. Unlike your standard aircraft tires, Bushwheels are tubeless. This distinctive design eliminates the problem of tire slippage and stem shearing and makes it possible to run these tires at very low PSI. Different models are offered to suit needs of aircraft operating conditions. ABI tires are FAA TSO C62d approved. Models are available in the following versions and fit standard 6" wheels unless otherwise mentioned:

Standard thread: 3/16"

Heavy thread: 1/4". Heavy tread 26" ABI tires are constructed with a thicker tread layer. Suitable for pilots operating their aircraft on pavement between backcountry flights.

The 26" ABI tires are designed and handcrafted for use on lighter aircraft such as Cessna 182 & Cessna 206. They're also the ideal "entry level" bush tires for pilots upgrading from standard tube type aviation tires for the first time.

A step up in terms of size, 29" ABI tires have a slighter profile and create less drag than larger Bushwheels. This places these bush tires in size/weight sweet spot for heavier aircraft like Cessna and Maule while still providing the footprint and energy absorption critical in bush landings. 

The 31" ABI tires are handcrafted featuring an impressive ratio of weight to size. Their solid footprint makes these bush tires the de facto standard for bush pilots.

The 35" ABI tires are designed for the most rugged off-airport operations. They require ABI 10650 10" wheels.

The 35" Beaver ABI tires stand up to the heavier load of de Havilland Beaver and Pilatus aircraft with a gross weight up to 5600 lbs (2800 static load rating per tire).
