SATO Ball Bearing (P57285200)

This flange-mounted ball supporter from SATO delivers smooth, low-friction omnidirectional movement for material handling and conveyor applications. Its 25.4 mm main ball and 80 support balls provide a dynamic load capacity of 25 kg, making it ideal for workstations, assembly lines, and transfer points where precise positioning is required.

Advantages

The carbon steel construction with zinc plating offers reliable corrosion resistance in standard industrial environments. A felt seal protects the internal ball race from dust and debris, reducing maintenance and extending service life. Self-lubricating operation eliminates the need for manual greasing, while the compact 34 mm overall height allows easy integration into existing conveyor frames or custom fixtures.
