Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes. As part of our B2B commitment, if a XRA7008C experiences unexpected issues in the field, PRS Bearings engineers can perform detailed metallurgical and wear analysis to identify root causes and optimize your future setups.
The standard XRA7008C from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 70 mm x 86 mm dimensions without warping.
The standard PRS Bearings XRA7008C is designed for rigid configurations. For optimal performance, strict alignment of the 70 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Every PRS Bearings XRA7008C is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 70 mm bore and 86 mm outer surfaces remain pristine during overseas transit.
