800555313 is a high-precision cylindrical roller bearing engineered for XCMG hydraulic excavators, providing robust radial load support for swing drives, travel motors, and final drive assemblies. This bearing is manufactured from premium bearing steel with precision-ground rollers and raceways, offering exceptional load capacity, low friction, and long service life under the extreme forces encountered in heavy digging and material handling operations. The 800555313 bearing features a separable design, allowing for easy assembly and maintenance, and its optimized internal geometry ensures efficient load distribution. This component is designed to reduce wear on mating parts and improve the overall efficiency of the excavator’s drivetrain.
The bearing’s surface is treated with a corrosion-resistant coating, protecting it from moisture and contaminants. Its high radial load capacity and low friction characteristics make it ideal for applications where space is limited and reliability is paramount.
By choosing the 800555313 cylindrical roller bearing, fleet operators can ensure reliable rotary support, reduce downtime, and extend the life of their excavators’ powertrain. This genuine XCMG part is a critical component for maintaining peak machine performance and durability.
The XCMG Cylindrical Roller Bearing 800555313 is designed to handle the immense radial loads generated by hydraulic excavator swing drives and travel motors. Its cylindrical rollers provide line contact with the raceways, offering high load-carrying capacity in a compact envelope, making it ideal for space-constrained applications.
The bearing’s rollers are precision-ground to ensure uniform geometry and optimal load distribution. This reduces stress concentrations, minimizing the risk of premature failure and ensuring smooth, consistent rotation even under severe shock loading.
The separable design of the 800555313 bearing allows for easy assembly and disassembly, simplifying maintenance and reducing downtime. The inner and outer rings can be mounted separately, enabling quick inspection and replacement of the rollers without disturbing the surrounding components.
By using the 800555313 bearing, fleet operators can enhance the reliability of their excavators’ drivetrain, reducing the risk of unplanned outages and costly repairs. Its robust construction ensures consistent performance throughout the machine’s service life.
Regular inspection of the bearing for signs of wear, pitting, or scoring is recommended. Early detection of issues allows for timely replacement, preventing damage to the shaft and housing and ensuring continued reliable operation.
The 800555313 cylindrical roller bearing is manufactured from high-quality GCr15 bearing steel, a material known for its excellent wear resistance, high hardness, and fatigue strength. This material is specifically formulated to withstand the high contact stresses encountered in heavy-duty off-road applications.
The bearing components undergo a carefully controlled heat treatment process that includes carburizing, quenching, and tempering. This process develops a hard, wear-resistant surface while maintaining a tough, impact-resistant core, providing an optimal balance of strength and durability.
The raceways are super-finished to achieve a surface roughness of Ra ≤ 0.1 µm, reducing friction and heat generation during operation. This smooth finish also improves the oil film retention, enhancing lubrication and extending the bearing’s service life.
All bearing surfaces are coated with a rust-preventive oil film for shelf-life protection, ensuring that the bearing remains in pristine condition until it is installed. This prevents corrosion and surface pitting during storage.
For operators in extreme climates, the bearing’s material stability ensures consistent performance over a wide temperature range, from -30°C to +120°C, maintaining clearance and load-carrying capacity within factory tolerances.
Installing the 800555313 cylindrical roller bearing requires careful attention to cleanliness and proper assembly techniques. Begin by thoroughly cleaning the shaft and housing to remove any debris, dirt, or old lubricant that could compromise the bearing’s performance.
Inspect the shaft and housing for any signs of wear, scoring, or out-of-roundness. If any damage is observed, the mating components should be repaired or replaced to ensure proper fit and load distribution. Use a dial indicator to verify shaft roundness.
Apply a thin layer of clean bearing grease or oil to the shaft and the inner ring bore to facilitate assembly. Carefully align the bearing with the shaft and use a suitable press or mounting tool to install it, ensuring that the force is applied evenly to prevent damage.
For maintenance, periodically monitor the bearing for signs of excessive noise, vibration, or temperature rise, which may indicate wear or lubrication issues. Regularly replenish the grease as per the manufacturer’s recommendation.
Always use genuine XCMG bearings to ensure correct material specifications and dimensional accuracy. Aftermarket bearings may not offer the same load capacity or durability, compromising machine safety and reliability.
