^{Heavy Equipment Bearing Catalogue and Cross Reference by Part Number}

Mahmut Usta Yedek Parça supplies high-quality bearings for construction equipment, mining machinery, haul trucks, road construction machines and heavy-duty off-road vehicles operating in demanding environments. Our heavy equipment bearing solutions are designed to deliver reliable power transmission, operational stability and long service life under high load and harsh working conditions, helping reduce total cost of ownership on construction and mining sites.

^{Bearing Types}

Our product range includes spherical roller bearings, tapered roller bearings, cylindrical roller bearings, needle roller bearings, ball bearings and slewing ring bearings designed for heavy-duty industrial applications. Bearing selection is based on load capacity, rotation speed and operating conditions to ensure smooth and efficient performance across all machinery types.

^{Bearings for Construction Equipment}

For construction equipment applications, we supply bearings suitable for drive and transmission systems, including transmissions, differentials, axles and planetary gear units for Caterpillar, Komatsu, Volvo, JCB, Hidromek, Liebherr, Doosan, Case and Terex machines. Components are matched by OEM part numbers to guarantee precise fit and optimal functionality.

^{Bearing Cross Reference by Part Number}

Bearings can be identified by original part number, by machine model or by dimensions. Send a number such as Komatsu 17M0921130, JCB 907/20000 or Caterpillar 6Y6488 and we will confirm availability and fitment. We provide a free bearing cross reference between OEM numbers and SKF, FAG, Timken, NSK, NTN and Koyo equivalents. If you only have the number stamped on the old bearing, send a photo of it and our technical team will identify the part.

^{Slewing Rings and Swing Bearings for Excavators}

The slewing ring bearing carries the entire upper structure of an excavator and is one of the most heavily loaded components on the machine. We supply slewing bearings, swing gear bearings and swing motor bearings for Komatsu, Caterpillar, Volvo, JCB and Hitachi excavators, in original and equivalent quality. Slewing rings are matched by machine model and part number, since dimensions, tooth count and bolt pattern differ between models of the same series.

^{Bearings for Mining Equipment and Haul Trucks}

We supply bearings for the mining industry and for rigid and articulated haul trucks working in quarries and open pit mines. Wheel hub bearings, final drive bearings, transmission bearings and suspension components are available for mining equipment operating under continuous high load and abrasive dust. Bearings for crushers, drilling rigs, conveyor systems and underground mining machines are supplied on request, matched by part number or by machine model.

^{Operating Conditions}

Bearings used in heavy machinery operate under extreme loads, continuous vibration and exposure to dust, mud and moisture. For this reason, our bearing solutions offer exceptional wear resistance, reduced maintenance requirements and extended service intervals to lower operational expenses.

^{Application Areas}

Our bearings are widely used in excavators, wheel and track loaders, dozers, motor graders, backhoe loaders, articulated and rigid haul trucks, hydraulic mining excavators, underground mining equipment, forestry machinery, skid steers and drilling rigs.

^{World-Leading Bearing Manufacturers}

Our inventory features genuine and equivalent bearings from world-renowned brands including SKF, FAG, NSK, Timken, NTN, INA and Koyo, engineered for heavy industrial operations.
