HZZ004733116 Slewing Bearing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The HZZ004733116 slewing bearing is a custom-made transmission component for engineering machinery, compatible with various slewing systems. Its core functions include transmitting slewing motion, heavy load bearing, and precise positioning. It features strong load-bearing capacity, smooth rotation, and wear-resistant sealing properties, making it suitable for high-vibration, high-load environments such as mines and construction sites. It can simultaneously withstand axial force, radial force, and overturning moment, ensuring smooth, uninterrupted equipment rotation and improving operational efficiency and safety.
As the core “load-bearing transmission unit” of the slewing system of engineering machinery, this product relies on a precision structural design and consists of inner and outer rings, rolling elements, cages, and seals. It balances load-bearing stability and slewing flexibility. Surface hardening treatment improves wear resistance, multiple sealing protections isolate impurities, corrosion resistance and easy maintenance extend the service life of the slewing system, and maintenance is convenient. It meets the JB/T2300-2011 industry standard and is a high-quality original part for repair, replacement, and bulk stocking.

【Core Technical Parameters】

— Product Model: HZZ004733116
— Product Type: Slewing Bearing (Original Equipment Manufacturer, Heavy-Duty Slewing Transmission Component for Engineering Machinery)
— Compatible Models: Sany, XCMG, Caterpillar and other series of construction machinery; suitable for replacing the slewing system of loaders, excavators, graders and other equipment; compatible with Sany SY55, SY60, SY205 excavators and STG140C-8S graders.
— Material: The outer and inner rings are made of high-strength alloy steel (50Mn/42CrMo), the rolling elements are made of GCr15 bearing steel, the cage is made of ZL102 cast aluminum alloy, and the seals are made of oil-resistant nitrile rubber; the surface hardness of the outer ring is HRC55-62, and the hardness of the rolling elements is HRC60-65.
— Operating temperature range: -30°C to +80°C (wide temperature stability, no brittleness at low temperatures, no aging at high temperatures, stable rotation performance, no jamming, suitable for various extreme working conditions)
— Structural Specifications: Single-row four-point contact ball structure, consisting of inner and outer rings, rolling elements, cage, sealing strip, and grease nipple. It features a built-in limiting mechanism to support relative rotation of the inner and outer rings, combining load-bearing, transmission, and positioning functions. It conforms to the layout of the equipment’s rotation system, with a compact structure and light weight.
— Load-bearing capacity: Can simultaneously withstand axial load, radial load, and overturning moment; axial load ≥ 500kN, radial load ≥ 200kN, overturning moment ≥ 1500kN·m; high rotational accuracy with no significant swaying; suitable for heavy-duty operation requirements.
— Size: Compatible with original factory rotary stations, tolerance grade IT7-IT8, raceway center diameter and mounting hole positions fully match original factory standards, mounting holes are threaded/smooth holes for precise fit, adapting to equipment installation requirements.
— Installation method: Bolt fixing, compatible with original mounting holes, easy installation without professional tools, smooth rotation after installation, no loosening or jamming, and can be seamlessly integrated with the equipment’s rotation system.
— Protective performance: Multiple oil-resistant seals provide IP65 protection, waterproof, dustproof, and oil-resistant; withstands salt spray test ≥96 hours; anti-aging and wear-resistant; suitable for dusty and humid construction site conditions; prevents impurities from entering the raceway; extends service life.
— Service life: ≥8 years under normal conditions, ≥5 years under harsh conditions, no abnormalities after 50,000 rotational cycles, no deformation, no jamming, no wear on the raceway, meeting the rated fatigue life (L10) standard.

Whether on construction sites, in mines, or in high or low temperature environments, this product can achieve heavy load bearing and smooth rotation, balancing load resistance and sealing performance to ensure precise and efficient equipment rotation and reduce the failure rate of the slewing system. Original factory compatible, requires no adjustment during installation, and is robust and durable, making it the preferred original part for replacing slewing bearings in construction machinery.
