Product Description
6904 Thin Wall Deep Groove Ball Bearing
6904 deep groove ball bearing belongs to thin-wall series rolling bearings, with standard dimensions of 20mm inner diameter, 37mm outer diameter and 9mm thickness. Compared with ordinary bearings, it features thinner wall, lighter weight and more compact structure, suitable for limited installation space and high-precision rotation scenarios. It is widely used in forklift steering mechanisms, small walking motors, hydraulic auxiliary parts and precision transmission components.
Manufactured with high-carbon chromium bearing steel and integrated quenching precision grinding technology, the 6904 bearing has uniform hardness, excellent wear resistance and anti-fatigue performance. It effectively reduces rotational friction, ensures flexible and stable operation, and avoids jitter, abnormal noise and stuck rotation during forklift mechanical operation. It maintains long-term stable precision in frequent start-stop and low-medium load working environments.
Available in multiple types including open type, 6904ZZ double metal shield and 6904-2RS double rubber seal. The sealed models effectively block dust, moisture and debris intrusion, prevent internal grease volatilization and leakage, and extend bearing service life. Standard industrial tolerance ensures zero modification and direct replacement, compatible with most mainstream forklift models and industrial precision machinery.
All 6904 forklift bearings pass strict dynamic and static load testing, rotational flexibility inspection and noise detection before delivery. Support retail and bulk wholesale, with independent anti-rust and dust-proof packaging. Provide global one-stop supply and professional model matching service.
