Technical Guide Slewing Bearings in Wind Turbines:Yaw & Pitch Bearing Requirements Explained June 2026 | Anhui Yuanfeng Slewing Bearing Co., Ltd. ◆ Wind turbines ask more of their slewing bearings than almost any other application. A crane bearing rotates continuously and can be inspected or replaced with relative ease. A bearing at the top of a wind turbine — installed 80 to 120 metres above ground — must operate reliably for 20 years with minimal intervention, under loads that shift constantly in direction and magnitude, in environments ranging from desert heat to Arctic cold to rain and dust. Understanding what separates a wind turbine slewing bearing from a standard industrial bearing is essential for engineers specifying these components and procurement teams...

Technical Blog The Practical Guide to Selecting Slewing Bearings for Truck-Mounted Cranes June 2026 | Anhui Yuanfeng Slewing Bearing Co., Ltd. ◆ Truck-Mounted Cranes (TMC) represent one of the most typical applications for slewing bearings. Their operating conditions are distinctive: intermittent heavy loading, side-pull impact from the boom, outdoor dust and moisture environments, and sudden rotation after long periods of idling. The consequences of improper selection—raceway pitting, gear wear, and downtime for repairs—translate into significant time and financial costs for crane operators. Our company specializes in manufacturing slewing bearings for TMCs from 3-ton to 200-ton capacities. Below is the practical selection framework we use when working with OEM custom...

  To the untrained eye, a slewing ring might look like just a massive steel circle. But as a manufacturer with nearly 20 years of history, we see it as the high-precision "heart" of a machine. Since our founding in 2007, we have been perfecting our craft. Today, we are opening our factory doors in Hefei to show you the journey of a slewing ring from raw steel to global shipment.     Material Selection: The Foundation of Strength   Every project starts with choosing the right steel. We select materials based on the specific environment where the machine will work, such as wind turbines or heavy-duty cranes.   50Mn: A high-performance choice for most general industrial machinery. 42CrMo: A tougher alloy steel for heavy loads and high-impact environments....
