⚡ Structural Advantages & Heavy-Duty Performance
Heavy Thick-Walled Outer Ring: Specially hardened, heavy-walled cylindrical outer ring designed to withstand continuous high-frequency impacts against baler plunger track rails without surface deformation.
Extended 30mm Width for Load Distribution: 30mm overall width distributes extreme compaction forces over a wider track contact area, preventing rail wear and operational misalignment.
Heavy-Duty Straw & Dust Sealing: High-efficiency contact rubber seals create a solid barrier against dry crop dust, straw debris, damp field slurry, and abrasive dirt contamination.
Maintenance-Free Pre-Lubrication: Pre-filled at the factory with high-grade wide-temperature agricultural synthetic grease, eliminating daily greasing downtime and lubricant washout.
🚜 Agricultural Machinery Deployment & Usage Scenarios
Claas Square Balers: Direct fit replacement plunger guide roller for Claas Markant 55, Markant 60, and Markant 65 small square balers, as well as Quadrant 3400 large square balers.
Welger AP Series Balers: Essential main piston/plunger roller bearing component for Welger AP45 series balers operating under continuous heavy baling cycles.
High-Impact Harvesting Equipment: Designed for severe-duty agricultural hay and forage equipment subjected to extreme reciprocating shock loads and dusty field environments.
