Product Description

Machine Lathed Male Rod End Bearing

Machine lathed male rod end bearing with 5-80 mm bore size designed for automatic production line applications.

Product Overview

Rod ends requiring maintenance are sliding bearings designed for regular lubrication through external oil nozzles or nipples. These bearings withstand medium to high loads in continuous high-frequency mechanical operations, providing long-term stable performance. Continuous lubrication reduces friction and wear, extending service life, making them ideal for industrial applications where frequent part replacement is challenging.

Product Features and Structure

Lubrication Method: Equipped with lubricating oil nozzles (oil cups) for regular manual or automatic lubrication system maintenance, ensuring continuous lubrication of sliding surfaces
Material Composition: Typically constructed from carbon structural steel bodies with bearing inner and outer rings featuring lubricating oil grooves. Some models utilize quenched bearing steel for inner rings to enhance wear resistance
Bearing Capacity: Capable of withstanding radial loads and axial loads in any direction not exceeding 0.2 times the radial load, suitable for swinging and tilting movements
Working Conditions: Ideal for applications with medium to high loads, frequent reciprocating motion, and significant environmental temperature changes, including construction machinery, hydraulic cylinders, and automation equipment

For left-hand thread, suffix "L" is added to bearing number and thread sign, e.g. SIL20ES M20x1.5L-6H.

SI..ES is equivalent to GIR..DO INA.

Industrial Applications

Specifically designed for automatic production line applications requiring reliable, maintenance-friendly bearing solutions

Frequently Asked Questions

Where is this bearing used?

Hydraulic cylinder and cylinder end connection
Automated production line linkage mechanism
Engineering machinery swing arm and steering system
Tensioning device for conveying equipment
Packaging and assembly equipment transmission joints

Why choose rod end bearings?

These bearings offer excellent durability, maintainability, and ability to adapt to complex working conditions, which is ideal for medium and high load mechanical systems.

Flexible installation and strong compatibility: Various connection forms such as internal threads (SI... ES) and external threads (SA... ES) provides easy matching and installation with different structural components. The double seam outer ring design also allows for a certain degree of pre tightening assembly, enhancing the rigidity of the connection.

How to choose the correct bearing size?

Select according to inner diameter, which determines the shaft diameter where the bearing will be installed.

Operation and Maintenance Tips

Ensure thread matching during installation to avoid axial deviation caused by forced tightening.
Clean the nozzle/nipple before oil injection to prevent impurities from entering the interior of the bearing.
Develop lubrication cycles based on operating frequency, and it is recommended to lubricate every 50-100 hours for high-frequency working conditions.
It is prohibited to operate beyond the allowable swing angle (usually ≤ 15°) and rated load.
It is recommended to install dust covers or sealing structures in high dust environments.
