Special Round Bore Agricultural Ball Bearings

SYSTEM DESCRIPTION:

High Material Durability:
These bearings are crafted from high-quality Chrome Steel (Gcr15), with a chemical composition that strictly adheres to international standards such as AISI 52100 (U.S.A.) and DIN 100Cr6 (Germany). The high hardness and wear resistance of this material allow the bearings to withstand the heavy loads and harsh environments typical of agricultural operations.
Superior Precision Control:
The products support a wide range of tolerance standards, from ABEC1 to ABEC7 (or P0 to P4). This high-precision capability ensures operational stability and low vibration, which is critical when agricultural machinery is running at high speeds or performing precision tasks.
Powerful Non-standard Customization:
Recognizing the diverse and complex structures of farming equipment, the company specializes in developing “various non-standard Custom Series”. This allows for tailored solutions that meet the specific dimensions or unique functional requirements of specialized agricultural tools.
Quality Reliability in Rigorous Conditions:
The manufacturing process is governed by the ISO9001 quality management system and the more advanced ISO/TS16949 system. Combining these international standards with highly-automated production equipment and complete testing methods, the company ensures consistent quality that minimizes equipment downtime during critical farming seasons.
