Radial Spherical Plain Bearing

Product Introduction

Radial Spherical Plain Bearings are designed to accommodate high radial loads, misalignment, and oscillating movements under demanding operating conditions.
The bearing consists of an inner ring with a spherical convex outside surface and an outer ring with a matching concave inside surface, allowing angular movement between shaft and housing.

These bearings are widely used in heavy-duty and structural applications where conventional rolling bearings are unsuitable due to shock loads, vibration, or low-speed oscillation.

Operating Conditions

• High radial loads and impact loads

• Low to moderate rotational speeds

• Oscillating, tilting, or intermittent motion

• Harsh environments with dust, moisture, or vibration

• Wide operating temperature range depending on liner material

Key Advantages

• High radial load carrying capacity

• Excellent misalignment compensation due to spherical sliding design

• Strong resistance to shock and vibration

• Simple structure with high reliability

• Maintenance-free options available, reducing downtime and operating costs

• Long service life even under severe working conditions

Structural Types

• Steel-on-steel radial spherical plain bearings

• Maintenance-free radial spherical plain bearings (PTFE liner)

• Sealed radial spherical plain bearings (2RS)

• Heavy-duty reinforced designs for extreme loads

Applications

• Construction machinery

• Mining and metallurgical equipment

• Hydraulic cylinders and lifting systems

• Engineering vehicles and agricultural machinery

• Industrial automation and mechanical linkages

• Shipbuilding and port machinery

• Power transmission and structural joints

OEM / Customization

This bearing supports OEM services and customization, allowing customers to specify brand labeling, lubrication options, precision tolerances, or packaging according to their requirements. It can be tailored to meet unique operational needs, ensuring optimal performance and full compatibility with customer-specific equipment.
