Rod Ends Requiring Maintenance Male Rod End Bearing SI 5E up to SI 80 ES GAR 5 GAR 80 DO
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
