Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The XRBH 2508 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 25 mm, an outer diameter of 41 mm, and a width of 8 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 8.0 mm and a balanced D/d ratio of 1.64 for high-precision housing fits.
The XRBH 2508 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 3.1 dynamic load rating without introducing excessive rotational inertia.
Longevity of the PRS Bearings XRBH 2508 is achieved through precise alignment and correct lubrication. The bearing's roller pitch diameter (Dpw: 32.5) plays a crucial role in load distribution and should be verified during maintenance. PRS Bearings also suggests regular monitoring of vibration levels to detect any signs of fatigue before they impact your production line.
The PRS Bearings XRBH 2508 features an advanced dual-sealing system with standard double seal (ds: 29) and double high-performance seal (Dh: 36) configurations. These specialized seals provide an effective barrier against dust, moisture, and contaminants, ensuring the internal raceways of the XRBH 2508 remain uncontaminated. This significantly reduces maintenance costs and extends service life.
