Function
The DG2003K.26.1-01 Bearing Positioning Retaining Ring is a precision-engineered locating component specially designed for Lovol series combine harvesters. It is a core hardware part for bearing, shaft and gear assembly positioning, primarily installed after bearing assembly to hold the bearing or hub assembly in the correct stop position, limit axial movement, and prevent component displacement. With a mature, reliable structure and strict dimensional control, this retaining ring ensures the stable operation of the harvester’s transmission system, gearbox and drive shaft assembly in harsh field conditions. It is tailored for professional farm maintenance teams, regional Lovol equipment parts distributors, and large-scale agricultural production entities that prioritize equipment safety, maintenance efficiency and component compatibility.
This Lovol combine harvester positioning retaining ring adopts a standard elastic-rigid ring structure with mature production technology and strict dimensional accuracy control. It delivers stable, consistent positioning performance, eliminating the risk of component loosening and axial displacement even under long-term vibration and load impact.
Compared with specialized locking mechanisms, this DG2003K.26.1-01 bearing retaining ring has extremely low unit cost and strong universality, adapting to multiple Lovol harvester models and components. It significantly reduces equipment maintenance and replacement costs, while avoiding the high expense of custom locking parts.
The retaining ring supports fast, tool-assisted installation and disassembly, enabling rapid replacement during equipment maintenance. This design drastically shortens harvester downtime, especially critical during peak harvest seasons, allowing maintenance teams to complete repairs quickly and restore equipment to operation.
Specially optimized for the complex working conditions of agricultural machinery, this agricultural machinery bearing lock ring maintains stable positioning performance in environments with alternating dust, moisture, vibration and heavy impact. It prevents component displacement caused by harsh field conditions, greatly improving the long-term reliability of the harvester’s transmission and gearbox systems.
Technical Parameters
| ITEMS | DESCRIPTION |
| Code | DG2003K.26.1-01 |
| Application | Suitable for multiple models of LOVOL (such as AF108/RG108 or its variants), including gear train, gearbox, drive shaft assembly, etc |
Product Uses
Axial positioning of rotating components: Installed in shaft grooves, shaft shoulders or housing grooves to prevent axial end movement of shafts, bearings and sleeve components during high-speed rotation and load-bearing operation, ensuring that core parts remain in the correct working position
Component fixation and anti-loosening: Acts as a physical stop between multiple assembled components, maintaining the preset fit gap and assembly state, preventing loosening and displacement caused by long-term vibration and heavy load impact during field harvesting
Auxiliary protection for transmission systems: Prevents bearing and gear displacement that could lead to transmission failure, reducing the risk of major equipment breakdowns and extending the service life of core transmission components
This harvester gearbox retaining gasket is fully compatible with Lovol combine harvester models including AF108, RG108 and their variant series. It also fits other Lovol harvester platforms with matching specification requirements for bearing positioning and axial locking components, as well as other agricultural machinery gearboxes and drive systems with compatible dimensional needs.
Product Operate Guide
Thoroughly clean before assembly
there should be no impurities, burrs, or corrosion inside the shaft shoulder and groove to ensure smooth installation of the retaining ring and prevent misalignment caused by debris.
The installation sequence is correct
usually, the bearings, sleeves, or other axial components should be installed in place first, and then the retaining ring should be installed to confirm that the subsequent components cannot push past the retaining ring position.
Check the locking status
For machines that have been in use for a period of time, it is recommended to check whether the retaining ring has shifted, become loose, or if the groove has become larger. If found, it should be repaired or replaced immediately
