WE51L, 5″ Wheel, External Caliper Brake





Matco Aircraft Landing Systems produces a superior 5″ inch wheel and brake assembly for use with aircraft requiring less than 1200 lbs per wheel. This model uses 1.25 inch TAPER/ROLL bearings. (Check the product comparison table for other bearing and caliper configurations).

DIMENSIONS – The WE51L is a 5″ inch wheel with 4.95 inch width with an additional 1.10 inch caliper spacing. Bearing spacing is 2.83 inches and axle spacing is 1.39 inches. The total weight of this wheel and brake assembly is 6.5 pounds. The bearing axle diameter is 1.25 inches.

FEATURES – The WE51L is cast utilizing a 535.2 aluminum alloy for superior strength and corrosion resistance. This alloy provides a light weight wheel and affords many years of efficient performance. The WE51L has a 1.25 tapered roller bearing which is rigorously tested and designed to resist bearing fatigue providing a long bearing life. This wheel features our ‘E’ series disc and single piston brake assembly. All ‘E’ series wheels utilize an external caliper for easy maintenance. Brake shoe removal can be accomplished by simply removing two bolts to release the caliper. Al-Ni-Brz bushings are used on ‘E’ series wheels to ensure smooth caliper travel.
Machining on this wheel optimizes its effectiveness when using a variety of manufacturer’s tires including Goodyear, McCreary, Michelin, and others. The WE51L can be used in conjunction with a bolt on axle, the A1A axle, for ease of installation. The A1A axle is manufactured using a black anodized 2024-T351 alloy and has a bolt hole diameter of 1.94. A straight 1.25 inch diameter axle may be used with 1.39 inch spacing between bearing and axle flange. For simplicity of installation, specify the WHLA1A axle or WHLAXLE1A axle assembly as the bearing stops are machined into the axle for correct caliper spacing.

TIRE/TUBE – Any 500X5 tire and tube combination can be used with this tire. Matco Aircraft Landing Systems recommends the Michelin Condor 500X5 6 ply.
