Complete ZM-120U Pneumatic Rear Travel Wheel Assembly (with Mounting Flange)

Complete ZM-120U Pneumatic Rear Travel Wheel Assembly (with Mounting Flange)

The complete pneumatic rear travel wheel assembly is a ready-to-install unit designed to ensure mobility, maneuverability, and smooth travel for ZM-120U grain throwers (as well as compatible soft-ride modifications ZM-60U and ZM-90U). It is supplied fully assembled and ready for installation, enabling quick replacement or upgrading of the rear travel system without requiring additional workshop fitting.

The design of the assembly combines a sturdy stamped steel R13 rim, a 155/70 R13 pneumatic tire, and a specialized rim mounting flange. This flange bolts directly to the metal rim and features a precise central mounting bore where the cylindrical hub protrusion (mounting flange) of the running axle snugly fits during installation, ensuring reliable centering and torque transmission.

Assembly Composition and Technical Specifications

• Assembly Name - Pneumatic Wheel with Flange ZP120 06.000.100
• Application - rear running gear of ZM-120U / ZMB-120U grain throwers (+ soft-ride ZM-60U, ZM-90U, ZMB-90U).
• Complete Unit Composition - stamped steel R13 rim, 155/70 R13 pneumatic tire (equipped with an internal R13 automotive inner tube or in a tubeless configuration), and a transitional (mounting) flange secured to the rim featuring a central mounting bore for the shaft hub protrusion.
• Connection Method - the flange is securely fixed inside the rim via standard bolts through factory holes, ensuring strict coaxiality and the absence of radial runout during rotation.
• Country of manufacture - Ukraine

Design Advantages of the Assembled Pneumatic Wheel with Flange for ZM-120

The use of a specialized rim mounting flange provides exceptional centering precision and high reliability for the entire running gear assembly. Thanks to a well-tolerated internal bore that precisely matches the hub protrusion on the shaft, the flange mounts securely onto the rim while maintaining perfect coaxiality-eliminating installation misalignments and allowing static and dynamic loads from the weight of the grain thrower to be evenly distributed directly onto the rim and hub.

At the same time, the R13 pneumatic tire ensures a soft ride, excellent handling, and effective vibration dampening during movement and operation of the grain thrower. It easily overcomes minor thresholds and unevenness, significantly reduces rolling resistance during maneuvering, and rolls more softly over grain heaps left on the surface, minimizing seed crushing. To maintain reliable pressure even under heavy loads and constant grain dust conditions, the unit can be equipped with a heavy-duty R13 automotive inner tube (UK-13) upon customer request. The assembly arrives in a state of complete operational readiness, meaning on-site installation requires only securing it to the shaft or rear travel hub of the grain thrower without any additional fitting or assembly.

Configuration Options and Associated Spare Parts for the Grain Thrower Pneumatic Wheel with Flange

You can order both the complete wheel assembly and its individual components for maintenance needs:

• Complete pneumatic wheel assembly with flange (rim, tire, inner tube/tubeless, mounting flange).
• R13 pneumatic rim (individually without tire and flange).
• Central rim mounting flange (individually for replacement in case of wear or deformation).
• R13 automotive inner tube (UK-13) or 155/70 R13 tires.

This pneumatic wheel assembly is engineered for modern ZM-120U grain throwers and hopper models manufactured by Zavod Moroza, which feature a gearmotor drive with an outboard differential located directly on the axle. Please note that this rim lacks the jaw half-clutches (wheel disconnect mechanisms) used in classic grain thrower versions with a self-propelled gearbox mounted on the frame. Therefore, upgrading an older machine to a pneumatic "soft ride" requires more than simply purchasing the wheels alone. The axle differential, gearmotor, and pneumatic wheels are designed as a single integrated kinematic unit, meaning conversion requires ordering the complete rear travel set. If you choose to independently upgrade your machinery's running gear, be sure to call or consult our engineers-we will guide you on how to correctly redesign the assembly and determine which parts are needed for the transition.

Buying the Complete ZM-120U Pneumatic Wheel from Zavod Moroza

Whether you are performing a spot replacement of a damaged wheel or planning a complete rear travel upgrade-ordering the pneumatic wheel assembly with mounting flange directly from Zavod Moroza ensures you receive a fully operational factory unit featuring verified geometry, precise centering, and complete element compatibility.
