WI60L Wheel Assembly, 6.0″ 1.25 TRB


Light Weight 6 inch wheel with ‘I’ Series Internal Caliper for Fast Brake Reline.



Matco Aircraft Landing Systems proudly announces a new six inch wheel and internal caliper brake assembly designed for the LSA market –the WI60L.  This six inch wheel with a 1.25 tapered roller bearing was designed specifically for use where a narrow profile six inch wheel is required.  The WI62L is identical to the WI60L but uses 0.75 inch tapered roller bearings.


The WI60L is a six inch wheel with a 4.1 inch width with an additional 1.1 inch caliper spacing.  Bearing spacing is 2.43 inches and axle spacing is 1.2 inches.  The total weight of this wheel and brake assembly is 5.8 pounds.  The bearing axle diameter is 1.25 inches.  A 1.0 inch spacer is available (model FI600L) to provide additional bead seat spacing when required.  The WI62L wheel & brake is identical but uses a 0.75 inch diameter axle.  This wheel requires a tube with a 90 degree valve stem. (see below)


The WI60L is centrifugally 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 WI62L has a 1.25 tapered roller bearing which is rigorously tested and designed to resist bearing fatigue providing a long bearing life. (specify the WI62L where 0.75 bearings are required)  This wheel features our new five inch I Series single piston brake assembly for excellent braking dynamics and easy brake maintenance allowing a brake reline to be done in a few minutes.  This wheel is designed to use the increasingly popular 4.00-6 tire and tube but wider tires can also be used.  The WI60L can uses the WHLA3 flange mount axle assembly.
