Material Specification:

Axis: Our Axis, crafted from cold drawn steel, is available in S235JRG2 (EN10027-1); ST37 (DIN17100); E24 (AFNOR NFA35501). The meticulous precision steel bar grinding achieves diameters of 20.2, 25.2, and 40.2 with ISO hll precision, ensuring exceptional reliability and strength for demanding applications.

Cylinder: Adhering to the stringent DIN2394 standards, our Cylinder is constructed from ST37 material, complying with DIN17100. This guarantees superior performance and dependability.

Bearing Pedestal: Our Bearing Pedestal is expertly crafted through a high-precision cold stamping process adhering to ISOM7. Utilizing deep stamping steel material meeting DIN1623-1624 standards, it combines cold rolling and calibration to deliver robust support and durability.

Inner Sealing Ring: The Inner Sealing Ring, manufactured with premium nylon6 (ISO PA6) lip seal material, offers unparalleled sealing capabilities, ensuring consistent performance.

Bearing: Utilizing a deep groove ball bearing with clearance class C3, our Bearing complies with the DIN 62, 63 series. This guarantees smooth, efficient operation for extended use.

Labyrinth Seal:Our Labyrinth Seal features a sophisticated 3-groove design, fabricated from high-grade ISO PA6 (nylon 6), offering superior sealing and remarkable durability.

Cover: Crafted from deep drawing steel EU10111-DD13, our Cover undergoes a robust cold impact processing, providing impressive resilience and long-term dependability.

Out Seal Ring: The Out Seal Ring, a Rubber sliding V-ring, is manufactured from wear-resistant, low-friction, and ozone-resistant NBR nitrile rubber, ensuring exceptional sealing and protection.

Protection Cover: Our Protection Cover, innovatively designed for mechanical protection, shields against stone impacts. Available in POM polymer or an anticorrosive zinc, aluminum, and copper alloy, it promises enduring defense and reliability.

Lubricating Grease: To ensure peak performance, employ our NLGI grade 2 or 3 lithium base grease, designed to be waterproof and dustproof. This grease enhances efficiency and provides long-lasting lubrication during assembly.

Idler Protection: Our Idler Protection utilizes premium finishes, including painting, plastic spraying, galvanizing, and anti-rust Tectyl oil, delivering comprehensive protection against corrosion and wear, prolonging the life of your equipment.
