Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every PRS Bearings PRG045 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 114.3 mm bore and 165.1 mm outer surfaces remain pristine during overseas transit.
PRS Bearings recommends storing the PRG045 in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
The PRG045 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 27,921 dynamic load rating without introducing excessive rotational inertia.
The PRG045 utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
