WHEEL & BRAKE ASSY 6”, 0.75 TRB, ”I” Series BI5-4 Caliper BPAE1.38CT


Light Weight 6 inch wheel For CT 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 WI62L-4.  This six inch wheel with a 0.75 tapered roller bearing was designed specifically for use where a narrow profile six inch wheel is required.  The WI62L-4 is identical to the WI62L but specific parts for the production version of the Flight Design CT.


The WI62L-4 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 0.75 inches.  A 1.0 inch spacer is available (model FI602L) to provide additional bead seat spacing when required.  The WI60L wheel & brake is identical but uses a 1.25 inch diameter axle.  This wheel requires a tube with a 90 degree valve stem. (see below)


The WI62L-4 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-4 has a 0.75 tapered roller bearing which is rigorously tested and designed to resist bearing fatigue providing a long bearing life. (specify the WI60L where 1.25 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 WI62L can use the WHLA8 tubular axle assembly for socket type installation or with the optional WHLA8BASE to allow flange mounting.


The WI62L-4 is designed for the following standards:

Static Capacity 1185 LBS
Load Limit 3555 LBS
Maximum Accelerate/Stop Kinetic Energy 105000 ft-lb
Torque Rating (@450 PSI ) 1980 in-lb
