Metric PSA20.544 slewing bearing with four-point contact ball bearing external gear 472 ID x 640.3 od x 56 wide mm VSA200544

Product Description:
The PSA20.544 Slewing Bearing with a four-point contact ball bearing and external gear is designed for heavy-duty applications that require high load capacity, smooth rotation, and durability. With a size of 472mm inner diameter (ID), 640.3mm outer diameter (OD), and a width of 56mm, this slewing ring bearing offers reliable performance for both radial and axial load handling. The VSA200544 is engineered to provide seamless and efficient motion in a variety of demanding environments, including robotics, construction machinery, and industrial automation.
This slewing bearing integrates a four-point contact design, ensuring even load distribution and minimizing friction for long-term, low-maintenance use. Additionally, the external gear provides easy integration with slewing drives, allowing for controlled rotation in precise motion systems. Ideal for use in excavators, robot bearings, and slewing drives, the PSA20.544 is a versatile and cost-effective solution for applications requiring high torque and precision.
