MATCO mfg produces a superior 6 inch wheel and brake assembly for use with aircraft requiring less than 660 lbs per wheel. This model uses 0.625 inch BALL bearings.


The MH6B is a 6 inch wheel with 5.375 inch width with an additional 1.24 inch caliper spacing. Bearing spacing is 2 inches and axle spacing is 2 inches. The total weight of this wheel and brake assembly is 4.4 pounds. The bearing axle diameter is 0.625 inches.


The NEW MH6B is now produced as a CNC spun wheel with a Tenzalloy hub center and a NEW higher torque caliper. The CNC spun wheel ensures the highest accuracy and repeatability without the problems associated with stamping wheels from aluminum. These wheels have a specially designed shoulder to ensure better seal and support of the tire bead seat and the material thickness is 30% greater than the older stamped wheel. The MH6B and MH6B.75 have a precision sealed ball bearing which is rigorously tested and designed to resist bearing fatigue. This wheel features an upgraded four inch brake assembly using the new PH-4XT caliper housing. (The four inch brake is available in three configurations for excellent braking performance to match the aircraft needs) All braking systems now available on the MH6B utilize caliper machined from bar stock instead of the older cast housings! When ordering parts for MH wheels using the new caliper, be sure to use the WHLB4XT parts listed in compatible products. For the old caliper, use the WHLB4.

Tire/Tube Because the MH6B uses an internal caliper, almost any six inch tire and tube combination can be used with this assembLy. Some of the most popular combinations are 15X600X6 2 ply or four ply tubeless for light use on paved surfaces; the 800X6 for rough and soft field landings; or a 600X6 aircraft tire for a higher profile and clearance.
Performance The MH6B is designed for the following standards:
Static Capacity: 660 LBS
Load Limit: 2000 LBS
Maximum Accelerate/Stop Kinetic Energy: 93441 ft-lb
Torque Rating (@450 PSI): 1540 in-lb
