Model 51317 pressure ball bearing (compatible with 8317) — supplied as 1 piece Key specifications Part numbers: 51317 and 8317 (compatible) Inner diameter (bore): 85 mm Outer diameter: 150 mm Width: 49 mm Quantity: 1 piece What this bearing does Provides precise, low-friction rotation while supporting both radial and axial loads. Maintains shaft alignment and smooth motion in assemblies that require stable, repeatable rotation. Standardized dimensions make installation and direct replacement straightforward in compatible housings and shafts. Why customers choose this bearing Reliable performance: Designed to deliver consistent rotation under load, reducing vibration and wear on connected components. Easy maintenance and replacement: Common dimensions (85 × 150 × 49 mm) simplify sourcing and swapping bearings during service. Mechanical stability: Robust envelope size provides solid support for larger shafts and housings where alignment and stiffness matter. Features and attributes Function: Supports radial and axial loads; enables precise rotation of rollers, shafts, and joints. Compatibility: Model 51317 with interchangeability to the 8317 variant for flexible sourcing. Size: 85 mm inner diameter, 150 mm outer diameter, 49 mm width — suitable for large-bore applications. Performance: Engineered for smooth rotation and alignment under demanding operating conditions. Supplied quantity: 1 piece Practical applications (examples) Conveyor roller assemblies in manufacturing lines — supports rollers for steady material flow and reduced downtime. Robotic joints or drive shaft supports in automated systems — maintains alignment and smooth motion under varying loads. Large-bore housings in agricultural or industrial machinery — provides stable bearing support in heavy-duty equipment. Notes and purchasing guidance Material, hardness, and tolerance details are not specified here; confirm these with the supplier to ensure proper fit, load capacity, and lubrication compatibility. Verify sealing and lubrication requirements for your application before installation to achieve expected service life.
