The MTZ-5 tractor utilizes a diverse range of bearings tailored to specific component requirements.
Single-row radial ball bearings are the most prevalent, applied across the power take-off (PTO) shaft, generator, hydraulic mechanism, engine components, differential, gearbox, clutch, drive pulley, and braking system. Variants include those with shielding washers, grooved outer rings, or double shields, catering to standard radial load needs.
Thrust ball bearings serve the engine speed governor shaft and front axle supports, designed to handle axial loads.
Angular contact ball bearings (with tapered outer rings, removable outer rings, or 12° contact angles) are used for the engine governor shaft front support, fuel pump/camshaft, and magneto, supporting combined radial and axial loads.
Short cylindrical roller bearings (in forms without inner rings/flanges or with single-flange inner rings) are deployed in the starting engine crankshaft, final drive, gearbox, and steering, delivering high load capacity for heavy-duty applications.
Needle bearings support the PTO front drive support and clutch intermediate shaft, ideal for compact, high-load spaces.
Tapered roller bearings (7608/7609) fit front wheel hubs, while conical angular contact roller bearings (977909) serve the steering worm, ensuring stability under combined loads.
These bearings, selected per relevant standards, ensure reliable operation across all tractor systems. The table below lists the specific bearing models used on the MTZ-5 tractor:
