Material Specification:

Axis: Engineered with precision and care, the axis is crafted from the finest cold drawn steel, including S235JRG2 (EN10027-1), ST37 (DIN17100), and E24 (AFNOR NFA35501). After meticulous processing with a steel bar grinder, the diameter is refined to 20.2, 25.2, 20.2, or 40.2 ISO hll accuracy, guaranteeing superior performance and unmatched durability.

Cylinder: Meticulously crafted to meet the high standards of DIN2394, the cylinder's ST37 material fully conforms to DIN17100 standards, ensuring unparalleled quality and exceptional durability.

Bearing Pedestal: The bearing pedestal, crafted with precision through cold stamping processing, adheres to ISOM7 precision standards. It undergoes rigorous cold rolling and calibration, and is made from deep stamping steel that meets DIN1623-1624 standards, offering reliability that is second to none.

Inner Sealing Ring: The inner sealing ring, made from premium lip seal material nylon 6 (ISO PA6), guarantees optimal sealing and impressive longevity.

Bearing: Equipped with precision-engineered deep groove ball bearings from the DIN 62, 63 series, these bearings are designed with clearance class C3 to ensure smooth operation and enhanced performance.

Labyrinth Seal:This advanced three-groove type labyrinth seal uses high-quality material ISO PA6 (nylon 6), providing excellent protection against contaminants and ensuring long-lasting resilience.

Cover: The cover is expertly manufactured from deep drawing steel EU10111-DD13, specifically processed for cold impact, ensuring robust protection, and unmatched durability.

Out Seal Ring: Crafted with precision from a rubber sliding V-ring, the out seal ring is composed of wear-resistant, low-friction, and ozone-resistant NBR nitrile rubber, providing lasting resilience in even the most challenging environments.

Protection Cover: Designed specifically as a mechanical protection bushing to ward off stone strikes, this cover is constructed from either POM polymer or an exceptionally durable anticorrosive zinc, aluminum, and copper alloy, offering superior protection that you can rely on.

Lubricating Grease: To ensure optimal long-term lubrication during assembly, our product utilizes waterproof and dustproof NLGI grade 2 or 3 lithium-based grease, ensuring superior performance and comprehensive protection.

Idler Protection: We offer a comprehensive range of protection options to safeguard your equipment. These include various types of painting, plastic spraying, galvanizing, and anti-rust Tectyl oil, all designed to ensure exceptional durability and longevity.
