Standard Grinding Head Needle Roller for Chains are made from high-quality materials that are durable and long-lasting. Its material hardness is HRC60~64, surface roughness Ra is not greater than 0.2, size range is Dw:3~30, Lw:5~50.They are designed to withstand heavy loads and extreme weather conditions, making them ideal for businesses that rely on outdoor operations.
One of the key features of our product is our use of ground heads. This ensures that our needle rollers have a smoother and rounder surface, decreasing chances of wear and increasing the lifespan of the product. This feature also helps reduce friction which translates to less energy expenditure thus improving the overall efficiency of the chain.
Product Attributes
Dimension standard
Produced strictly in accordance with industry standards, the diameter tolerance is controlled within a very small range to ensure the matching accuracy with the chain, and can adapt to chains of various specifications.
Head grinding
The head is precisely ground, with low surface roughness and a standard round shape, which can reduce friction with the chain connection and improve transmission efficiency.
Tough material
High-quality bearing steel is selected, and after quenching and tempering, the Rockwell hardness reaches 58-62HRC, with good wear resistance and fatigue resistance.
Good cylindricality
The cylindricality error is controlled within 0.001mm to ensure uniform force and smooth operation during chain transmission.
Surface treatment
Hard chrome plating is used, with high surface hardness and strong rust resistance, which can adapt to different working environments.
