ZM-120U Pneumatic Wheel Rim (3 Holes, R13 "Tavria")

ZM-120U Pneumatic Wheel Rim (3 Holes, R13 "Tavria")

The ZM-120U pneumatic wheel rim is a stamped steel R13 rim with a distinctive 3-hole bolt pattern, designed for installation in the running system (rear travel) of our modern ZM-120U grain throwers. The component serves as a robust, rigid base for mounting a pneumatic tire and transfers loads from the agricultural machinery frame to the threshing floor surface.

The design is based on the standardized running gear rim of the "Tavria" vehicle family (ZAZ-1102), ensuring high maintainability, precise geometry, and ready availability of spare parts in the event of mechanical rim damage.

Technical Specifications of the ZM-120U Pneumatic Wheel Rim:

• Name - R13 pneumatic wheel rim
• Application - rear running gear of ZM-120U grain throwers
• Tire seating diameter - 13 inches (for standard 155/70 R13 tire sizes)
• Mounting (bolt pattern) - 3 mounting holes (ZAZ-1102 "Tavria" standard) for attachment to the rear travel hub
• Material - high-strength stamped sheet steel with a protective anti-corrosion enamel coating
• Tire compatibility - engineered for installing both tubeless tires and standard tires using an inner tube
• Country of manufacture - Ukraine

Operating Features and Configuration Options

The design of the rim bead flange is optimized for a secure tubeless tire fit. However, operating agricultural machinery on a threshing floor presents specific nuances:

• Tubeless use - provides a lightweight wheel and simple installation when utilizing high-quality tubeless rubber.
• Use with an inner tube (recommended for agricultural machinery) - due to constant high loads from the grain thrower's weight, driving over small thresholds and obstacles, and exposure to grain dust, a tubeless wheel can gradually lose pressure along the bead. Installing a standard R13 automotive inner tube (UK-13) inside the tire guarantees stable pressure and prevents the wheel from constantly going flat.

Option to Order a Kit or Complete Wheel Assembly

This catalog item provides for the supply of an individual wheel rim (without a tire or inner tube), which is a cost-effective solution if only the metal base of your equipment is bent or damaged while the rubber remains intact. However, you can also order:

• Complete R13 pneumatic wheel assembly (rim + 155/70 R13 tire + R13 inner tube - fully ready for installation on the mounting flange / hub).
• Individual components such as the R13 automotive inner tube, 155/70 R13 tire, or the 3-bolt rear travel flange (hub).
• Complete rear travel kit - running axle with a gearmotor and axle differential assembled with pneumatic wheels for upgrading legacy grain throwers.
