Single direction thrust ball bearings are designed to accommodate axial loads in one direction only and must not be subjected to radial loads. Their separable design allows for easy mounting, dismounting, and maintenance inspections, making them convenient for a variety of applications. Interchangeable components enhance versatility and simplify replacement, while the ground bore on the shaft washers enables an interference fit for secure and reliable positioning. These features make single direction thrust ball bearings an efficient choice for directional load-bearing needs. - Specification: Item 51211; Bore Diameter 55.00 mm; Outside Diameter 90.00 mm; Width, Total 25.00 mm; Width, Inner Ring 25.00 mm; Width, Outer Ring 25.00 mm; Basic Dynamic Load Rating (Cr) 58.5 kN; Basic Static Load Rating (C₀r) 134 kN; Limiting Speed 4,000 r/min; Rolling Element Ball; Number of Rows 1; Locating Feature (Outer Ring) Without; Bore Type Cylindrical; Cage Material Sheet metal; Radial Internal Clearance —; Tolerance Class P6; Bearing Material GCr15; Sealing Without; Sealing Type —; Lubrication None; Relubrication Feature Without; Product Weight 0.57 kg.
