Material Specification:

Axis: Crafted from cold drawn steel S235JRG2 (EN10027-1); ST37 (DIN17100); E24 (AFNOR NFA35501), our steel bar grinder meticulously processes the diameter to 20.2, 25.2, 20.2, and 40.2, maintaining ISO hll accuracy for unparalleled precision.

Cylinder: Adhering to the DIN2394 standard, the material is ST37 and aligns with the stringent specifications of the DIN17100 standard.

Bearing Pedestal: Expertly crafted through cold stamping processing that conforms to ISOM7 precision, this component undergoes cold rolling and calibration. The raw material, deep stamping steel, meets the high standards of the DIN1623-1624 standard.

Inner Sealing Ring: Lip seal material is composed of nylon6 (ISO PA6), offering exceptional resilience and performance.

Bearing: Utilizes deep groove ball bearings (clearance class C3) from the DIN 62, 63 series, ensuring reliable and smooth operation.

Labyrinth Seal:3 groove type, crafted from ISO PA6 (nylon 6) material, providing robust sealing capabilities.

Cover: Made from deep drawing steel EU10111-DD13, it undergoes cold impact treatment for enhanced durability and strength.

Out Seal Ring: This rubber sliding V-ring is crafted from wear-resistant, low-friction, and ozone-resistant NBR nitrile rubber, offering exceptional long-lasting performance.

Protection Cover: Designed as a mechanical protection bushing to prevent stone strike, crafted from POM polymer or an anticorrosive zinc, aluminum, and copper alloy for heightened durability.

Lubricating Grease: Employ waterproof and dustproof NLGI grade 2 or 3 lithium base grease, ensuring long-term lubrication during assembly for optimal performance.

Idler Protection: Features multiple protective options including painting, plastic spraying, galvanizing, and anti-rust tectyl oil, ensuring comprehensive protection against environmental factors.
