Description
Radial spherical plain bearings requiring maintenance are used for heavy-load oscillating or tilting motion applications where periodic lubrication is feasible, such as construction machinery, hydraulic cylinders and mining equipment.
GEZ312ES-2RS Joint Bearings Features and Advantages
Reliability: High load capacity and durability reduce failures and downtime.
Structural Design: The inner and outer rings feature spherical and inner spherical surfaces, allowing rotation and swinging at any angle.
Load Capacity: Capable of withstanding significant radial and axial loads, suitable for high-stress and heavy-duty applications.
Self-Aligning Function: Equipped with self-aligning characteristics, it can automatically adjust during installation errors or movement, ensuring smooth operation.
Application: Widely used in fields such as engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automotive shock absorbers, and hydraulic machinery.
QIBR - GEZ312ES-2RS Joint Bearings Optimization
High-performance materials: Bearing materials can be replaced based on different working conditions, such as FRP, bearing steel, stainless steel, and other materials.
Surface Treatment: The bearing surface can be treated according to customer requirements, including phosphating, galvanizing, chrome plating, and lining, padding, or spraying on the sliding surfaces.
More customization: QIBR can design and optimize bearings based on customer usage conditions and needs.
QIBR - GEZ312ES-2RS Joint Bearings Quality Control
Dimension measurement: Various professional high-precision instruments are used to measure multiple dimensions of the bearing, with the highest precision reaching 0.001mm.
Rotational Accuracy: A dial gauge measures small surface defects or deviations, with a measurement accuracy of up to 0.001mm.
Hardness measurement: Use a hardness tester to measure the surface hardness of the guide rail, with a measurement accuracy of ±0.5HRC.
Metallographic Analysis: The internal metallographic structure of the metal is analyzed using a professional metallographic microscope.
Noise Monitoring: Vibration data is obtained by monitoring the vibrations during operation with a vibration meter.
Geometric tolerance: Use a profiler to measure the geometry and relative position of the guide rail.
Raw material control: Procurement of steel and parts from ISO 14001 certified suppliers ensures product stability while promoting sustainable development.
