Core Features:
Features a spherical sliding contact structure, allowing for relatively large misalignment angles (typically 2°–10°, some models up to 30°), compensating for shaft and bearing housing installation errors, shaft deflection, and housing deformation.
Primarily bears radial loads; some types (such as angular contact spherical plain bearings) can withstand bidirectional axial loads or combined loads; capable of withstanding impact loads and vibrations, suitable for heavy-duty applications.
Compact structure, available in radial, angular contact, and thrust types; no rolling elements, operates through spherical sliding friction, requiring no high-precision machining, and easy to install.
Higher coefficient of friction than rolling bearings, lower limiting speed, primarily used for low-speed oscillating, rotating, or reciprocating motion applications; requires regular lubrication (primarily grease lubrication, oil lubrication optional for high-speed/high-temperature applications).
Can be paired with different materials (e.g., steel-steel, steel-bronze, steel-PTFE composites) to meet various application requirements such as wear resistance, corrosion resistance, and self-lubrication.
Typical Application Scenarios:
Construction Machinery – Boom joints, stick pins, slewing bearings, and hydraulic cylinder ends of excavators, loaders, and cranes; the core suitability is due to significant angular misalignment, heavy loads and impacts, and harsh operating conditions.
Automotive Industry – Suspension systems, steering mechanisms, universal joints of drive shafts, and shock absorbers; the core suitability is due to compact space requirements, allowing for sway angles, and the ability to withstand impact loads.
Aerospace – Aircraft landing gear, helicopter rotor systems, servo motors, the core suitability is due to lightweight design, and tolerance to extreme temperatures and vibrations.
General Machinery – Roller joints of papermaking machines, textile machines, and printing machines; swaying mechanisms in packaging machinery; and stability under heavy loads.
Medical Devices – Operating tables, rehabilitation equipment,the core suitability is due to flexible angle adjustment, noiseless operation, self-lubrication, and good biocompatibility.
