Product Description
570919 Tensioner roller is key chain‑tensioning component designed for CLAAS combine harvester transmission system.
**Material features**: Made of high‑strength alloy with wear‑resistant surface treatment, built‑in bearing assembly. It delivers good impact resistance and wear performance, able to withstand continuous vibration, dust and crop debris under harsh field harvesting conditions.
**Product characteristics**: This tensioner roller applies pressure to roller chain, compensates for chain elongation caused by long‑term wear, eliminates chain slack, avoids chain jumping and slipping. Worn roller surface, seized bearing or deformed roller body will lead to loose chain, abnormal noise and power transmission interruption, causing harvest downtime.
**Compatibility**: Direct aftermarket replacement matching OEM 570919, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Inspect chain wear condition, adjust tension travel to achieve proper chain tension after installation. Install 570919 tensioner roller to stabilize chain drive performance of your Claas harvester.
