Material Specification:

Axis: Our axis is crafted from cold drawn steel S235JRG2 (EN10027-1); ST37 (DIN17100); and E24 (AFNOR NFA35501). Precision is ensured as the steel bar grinder processes the diameter to 20.2, 25.2, 20.2, and 40.2 ISO h11 accuracy, providing reliability and consistency.

Cylinder: The cylinder meets the stringent requirements of the DIN2394 standard, utilizing ST37 material that adheres to the DIN17100 standard, ensuring robust strength and durability.

Bearing Pedestal: Manufactured through cold stamping processing that aligns with ISOM7 precision. The raw material is deep stamping steel that complies with the DIN1623-1624 standard, ensuring exceptional quality and performance.

Inner Sealing Ring: The lip seal is composed of nylon6 (ISO PA6), offering superior sealing capabilities and enhanced durability.

Bearing: Equipped with a deep groove ball bearing, featuring clearance class C3, and conforming to the DIN 62, 63 series, for optimal performance and longevity.

Labyrinth Seal:3-groove type design, crafted from ISO PA6 (nylon 6), providing exceptional sealing efficiency in challenging conditions.

Cover: Constructed from deep drawing steel EU10111-DD13, known for its resilience and subjected to cold impact for enhanced durability.

Out Seal Ring: Made from a rubber sliding V-ring, this seal is crafted from wear-resistant, low friction, and ozone-resistant NBR nitrile rubber, ensuring lasting performance.

Protection Cover: Designed with a mechanical protection bushing to safeguard against stone strikes. The material used is either POM polymer or an anticorrosive zinc, aluminum, and copper alloy, providing robust protection.

Lubricating Grease: We utilize waterproof and dustproof NLGI grade 2 or 3 lithium base grease for long-term lubrication, enhancing the lifespan and reliability of the assembly.

Idler Protection: Includes various protective measures such as painting, plastic spraying, galvanizing, and anti-rust tectyl oil, ensuring longevity and resilience in diverse conditions.


Our company specializes in the R&D and production of belt conveyors, focusing on all varieties of idler, roller, and idler support. Idlers play a crucial role in belt conveyors, effectively supporting both the conveyor belt and the materials it carries, ensuring smooth and efficient operation. Different diameters are available, adhering to both domestic and international standards.

Domestic Standards: D63, 76, 89, 108, 133, 159, 194, 219 - crafted to meet the highest standards of quality and performance.
Foreign Standards: D60, 76, 78, 89, 102, 114, 127, 139, 152, 165, 178, and more, catering to international specifications for global applicability.
