How Our Slewing Drives Achieve Long-Term Corrosion Protection?
2026-03-31
Slewing drives used outdoors face wind, rain, humidity, and pollutants. Their corrosion resistance directly affects service life and reliability. We don’t just sell components—we offer long-term performance you can trust. That’s why every slewing drive we produce undergoes a rigorous anti-rust treatment. Our complete surface finishing process ensures each unit achieves a C4 corrosion protection rating, verified by a 720‑hour neutral salt spray test.
Essential Characteristics of Robot Joint Bearings
2026-03-30
Robot joint bearings are often referred to as the "joints" of a robot; their precision, load capacity, and service life ultimately determine the robot's overall operational lifespan. Unlike standard bearings, robot joint bearings must maintain stability and balance throughout a series of complex movements. Depending on the specific type of robot and its intended application, the core characteristics required of these bearings can be summarized in the following five points:
Selecting Materials for Slewing Bearings: 42CrMo vs. 50Mn
2026-03-30
For slewing bearings, 42CrMo represents an upgraded option offering superior performance compared to 50Mn, particularly excelling under harsh operating conditions involving heavy loads, impact forces, or low temperatures. Generally, 50Mn suffices for standard requirements, whereas 42CrMo delivers enhanced performance for applications demanding high reliability.
Why choose 50Mn Material for Small and Medium-Sized Truck Cranes Slewing Bearing?
2026-03-30
Small and medium-sized truck cranes typically have a lifting capacity of less than 25 tons. Consequently, the loads and overturning moments experienced by the truck cranes slewing bearings fall well within the safe load-bearing range of 50Mn material. While fully satisfying all performance requirements, 50Mn offers superior cost-effectiveness and process maturity. Therefore, ARI bearing highly recommend using 50Mn material for truck crane bearings.
