Main wheels are designed to support the larger portion of the load requirements for the aircraft along with the nose wheels. The main wheels transmit stopping forces from the brake to the ground.&nbsp;Wheels are made from either aluminum or magnesium castings, or aluminum forgings. Cleveland’s wheels are the divided type, incorporating an inner and outer wheel half, plus a disc, which are fastened together with tie bolts, washers, and nuts. The wheel rotates on two tapered roller bearings which seat in bearing cups, shrink fitted into the hubs. Molded grease seals provide protection and lubricant retention for the bearings. Hubcaps, when used, are secured to the outboard wheel half by a snap ring and screws.&nbsp;&nbsp;APPLICATIONS&nbsp;General and business aviation, turboprop passenger, and helicopter&nbsp;FEATURES AND ATTRIBUTES&nbsp;<ul><li>Low maintenance for tubeless or tube-type</li><li>Tapered roller bearings for dimensional stability and long life</li><li>Molded grease seals for superior bearing bore sealing properties</li><li>Split-rim design to allow ease of tire mounting</li><li>High-strength through-bolts</li><li>Sand castings and forgings</li><li>Worldwide distributor network for quick parts availability</li><li>&nbsp;</li></ul>OPTIONAL FEATURESDesigned to meet aircraft specifications and brake assembly interface
