Axis: Crafted from cold drawn steel S235JRG2 (EN10027-1); ST37 (DIN17100); E24 (AFNOR NFA35501). The steel bar grinder precisely processes the diameter to 20.2, 25.2, 20.2, 40.2 with ISO hll accuracy, ensuring exceptional durability and precision.

Cylinder: Manufactured in accordance with the esteemed DIN2394 standard. The material, ST37, is meticulously chosen to meet the DIN17100 standard, promising unparalleled performance.

Bearing Pedestal: Engineered through cold stamping processing that adheres to ISOM7 precision. This method includes cold rolling and calibration, utilizing deep stamping steel that meets the DIN1623-1624 standard, ensuring robust structural integrity.

Inner Sealing Ring: Constructed from lip seal material nylon6 (ISO PA6), offering superior sealing performance and longevity.

Bearing: Features deep groove ball bearings with a clearance class of C3 within the DIN 62, 63 series, ensuring smooth and reliable operation.

Labyrinth Seal:This 3 groove type seal, made from ISO PA6 (nylon 6), provides exceptional protection against the elements, enhancing the lifespan of the equipment.

Cover: Fabricated from deep drawing steel EU10111-DD13, subjected to cold impact, ensuring superior strength and resilience.

Out Seal Ring: Composed of a rubber sliding V-ring, utilizing wear-resistant, low friction, and ozone-resistant NBR nitrile rubber, offering unmatched durability and sealing efficiency.

Protection Cover: Superior mechanical protection bushing designed to withstand stone strikes. Available in POM polymer or an anticorrosive alloy of zinc, aluminum, and copper for robust protection.

Lubricating Grease: Utilizes waterproof and dustproof NLGI grade 2 or 3 lithium base grease, ensuring long-term lubrication during assembly, offering outstanding performance under demanding conditions.

Idler Protection: Features a range of protective treatments including painting, plastic spraying, galvanizing, and anti-rust tectyl oil, safeguarding the idler against environmental challenges.
