Material Specification:

Axis: Our axis is meticulously engineered from cold-drawn steel grades S235JRG2 (EN10027-1), ST37 (DIN17100), and E24 (AFNOR NFA35501). This ensures unparalleled precision, as enhanced steel bar grinders refine diameters to 20.2, 25.2, 20.2, and 40.2 ISO h11 accuracy, guaranteeing unwavering reliability and excellence in every operation.

Cylinder: The cylinder is crafted to meet the rigorous DIN2394 standard, utilizing ST37 material compliant with DIN17100 standards, delivering formidable strength and enduring durability.

Bearing Pedestal: The bearing pedestal is expertly manufactured through a cold stamping process in alignment with ISOM7 precision standards. Using premium deep stamping steel that meets DIN1623-1624 standards, it ensures remarkable quality and outstanding performance.

Inner Sealing Ring: Featuring a lip seal made from nylon6 (ISO PA6), this component boasts superior sealing capabilities and heightened durability, ensuring reliable performance under demanding conditions.

Bearing: Our bearings incorporate deep groove ball bearings with clearance class C3, adhering to the DIN 62, 63 series standards for unmatched performance and extended longevity.

Labyrinth Seal:A sophisticated 3-groove type design, crafted from robust ISO PA6 (nylon 6), ensures unprecedented sealing efficiency, even in the most challenging environments.

Cover: This cover is crafted from deep drawing steel EU10111-DD13, renowned for its resilience and subjected to cold impact treatment to amplify its durability.

Out Seal Ring: Composed of a rubber sliding V-ring, this seal features wear-resistant, low-friction, and ozone-resistant NBR nitrile rubber, delivering enduring performance and reliability.

Protection Cover: Designed with a robust mechanical protection bushing to shield against stone impacts, utilizing materials like POM polymer or a corrosion-resistant zinc, aluminum, and copper alloy for supreme protection.

Lubricating Grease: We employ NLGI grade 2 or 3 lithium base grease, noted for its waterproof and dustproof properties, providing superior long-term lubrication that significantly enhances the assembly's lifespan and reliability.

Idler Protection: Features a comprehensive range of protective measures including painting, plastic spraying, galvanizing, and anti-rust tectyl oil, ensuring exceptional longevity and durability in a variety of operational conditions.


Our expertise lies in the R&D and production of belt conveyors, with a particular emphasis on all types of idlers, rollers, and idler supports. Idlers are pivotal components in belt conveyors, efficiently supporting both the conveyor belt and the materials it transports, ensuring seamless and effective operations. Our offerings are available in various diameters, conforming to both domestic and international standards.

Domestic Standards: D63, 76, 89, 108, 133, 159, 194, 219 - meticulously crafted to meet and exceed the highest benchmarks of quality and performance.
Foreign Standards: D60, 76, 78, 89, 102, 114, 127, 139, 152, 165, 178, and more - designed to meet international specifications, ensuring global adaptability and compliance.
