800515285 XCMG GR2605 motor grader spherical plain bearing

800515285 spherical plain bearings are core wear-resistant components in the transmission and connection parts of engineering machinery. They are used to bear radial loads, enabling flexible oscillation and rotation, adapting to heavy-duty and high-frequency operating conditions, reducing friction and wear, and ensuring the smooth operation of moving parts of equipment.

Core Technical Parameters

Model: 800515285
Type: Radial Spherical Plain Bearing (General Purpose, Suitable for Multi-directional Forces)
Material: High-carbon chromium bearing steel (High hardness and high wear resistance after heat treatment)
Surface Treatment: Blackening treatment + anti-rust oil coating (Improves corrosion resistance and wear resistance)
Operating Temperature: -40℃ ~ +120℃ (Suitable for outdoor and heavy-duty construction environments)
Load Characteristics: Primarily bears radial loads, allowing for small-angle oscillation and rotation without jamming.
Matching Type: Interference or transition fit with shafts and bearing housings, ensuring secure and stable installation.
Applicable Scenarios: Used in engineering machinery for connecting joints, transmission mechanisms, oscillating parts, and other locations requiring flexible movement and bearing loads.

Core Functions and Effects

Friction Reduction and Wear Resistance: Reduces the coefficient of friction between moving parts, minimizing wear and preventing damage caused by dry friction.

Flexible Movement: Allows the connecting parts to oscillate and rotate within a small range, meeting the flexibility requirements of equipment operation.

Load Transmission: Smoothly transmits radial loads, distributing force and preventing localized stress concentration that could damage the connection structure.

Shock Resistance: Absorbs minor impacts during operation, protecting connected components and extending equipment lifespan.

Suitable Applications

Widely used in articulated parts and swing connection structures of construction machinery such as excavators, loaders, and bulldozers, including boom connections, bucket linkage mechanisms, and chassis swing components; also suitable for transmission connections in mining and agricultural machinery, adaptable to heavy-duty and frequent-movement operating conditions.
