800554952 XCMG GR2605 motor grader tapered roller bearing

XCMG original single-row tapered roller bearings for construction machinery are suitable for the transmission, axle housing, and running gear systems of graders, loaders, etc. They can withstand radial and unidirectional axial loads, offering strong load-bearing capacity, impact resistance, and ensuring stable shaft operation.

Core Definition and Structure

Type: Single-row tapered roller bearing (separate design, inner ring, roller-cage assembly, and outer ring can be installed separately)

Structure: Both inner and outer rings have tapered raceways; rollers have a logarithmic profile with flange guidance, forming a contact angle capable of simultaneously withstanding radial and axial loads.

Material: High-carbon chromium bearing steel (e.g., GCr15), high hardness and good wear resistance after heat treatment; cages are mostly made of stamped steel or solid brass, suitable for heavy-duty applications.

Key Technical Parameters (Original Equipment Manufacturer Standard)

Part Number: 800554952
Type: Single-row tapered roller bearing
Core Dimensions (mm, based on actual machine drawings): Inner diameter × Outer diameter × Width (e.g., common 50×110×42, 60×130×50, etc., matched to XCMG complete machines)
Contact Angle: Standard design, balancing radial and axial load distribution
Rated Load: Dynamic load / Static load meets the heavy-duty requirements of construction machinery, with impact and fatigue resistance.

Compatible models: XCMG GR series graders, LW series loaders, road rollers, etc., including drive axles, transmission axles, and gearbox output/input shafts.

Operating temperature: -40℃～+120℃ (normal working conditions); high-temperature materials can be selected for special working conditions.

Applicable scenarios and core advantages

Applicable working conditions: Unpaved roads such as mines, infrastructure, and sand and gravel pits; transmission systems, drive axles, gearboxes, and other parts subjected to heavy loads and impacts.

Core advantages: Separate structure facilitates installation and maintenance; logarithmic profile rollers optimize stress distribution and improve lifespan; edge guidance ensures stability and resists angular errors; original factory matching ensures high installation accuracy and reduces vibration and wear.

Purchasing and matching reminders

Purchase original factory parts according to part number 800554952, ensuring size and load rating match.

Use bearings of the same specification; shaft and seat bore accuracy must meet drawing requirements.

After installation, run the machine idle for a test run; only put it into heavy-duty operation if there is no overheating or abnormal noise.
