Shandong Huashou Transmission Technology Co., Ltd. is one of the leading manufacturers and suppliers of cylindrical rolling bearing in China. With abundant experience, we are committed to providing high quality customized products with competitive price. Welcome to wholesale bulk durable cylindrical rolling bearing in stock here from our factory. Also, pricelist is available.
Products Description
All three products are manufactured in strict accordance with OEM standards, featuring precise dimensional tolerances and perfect assembly fit. They maintain stable, reliable operation under extreme loads and harsh outdoor environments. Additionally, they offer excellent cross-brand compatibility; beyond fitting the corresponding bulldozer models (TY220/TY320/YJ380), they are also suitable for mainstream equipment from manufacturers such as Liugong, XCMG, and Zoomlion. As premium aftermarket replacements, they allow for direct installation without the need for cutting or on-site modification.

Product Features
Materials & Manufacturing: Made from high-strength alloy steel (with forged alloy steel used for certain models). They undergo standardized heat treatment, surface strengthening, and rigorous multi-stage quality inspections, resulting in high hardness and excellent compressive strength, wear resistance, and fatigue stability.
Application Scenarios: Suitable for harsh operating conditions such as mining, large-scale earthworks, and road construction; performance remains stable during long-term, high-frequency operations.
Performance Benefits: Reduces internal friction and energy loss, lowers equipment failure rates, extends maintenance intervals, reduces long-term O&M costs, and prevents losses caused by construction downtime.
International Standards: All products have passed international export inspections and meet the requirements for long-term, high-intensity continuous operation.
Support Services: We provide a comprehensive range of OEM-standard bulldozer transmission and hydraulic components (gears, drive shafts, oil seals, friction discs, planetary carriers, torque converters, hydraulic valve assemblies, etc.). Mainstream parts are kept in stock for immediate availability. We support flexible global shipping options (sea, air, and express), provide complete export customs clearance documentation, and offer professional technical guidance.
