Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PRG042 is designed for rigid configurations. For optimal performance, strict alignment of the 107.95 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Under optimal lubrication conditions, the PRS Bearings PRG042 can reach a limiting speed of 3,810 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
The L10 life of the PRS Bearings PRG042 is calculated based on its 26..961 dynamic capacity and your specific application loads. By maintaining clean operating conditions and using PRS Bearings's recommended lubrication, users can expect significantly extended service intervals.
Every PRS Bearings PRG042 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 107.95 mm bore and 158.75 mm outer surfaces remain pristine during overseas transit.
