Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HRA5008 HRAU Series Crossed Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 50 mm bore. For the 66 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
The Single-sided or Double-sided Sealed engineered for HRA5008 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies HRA5008 with a precision bore diameter (d) of 50 mm, an outside diameter (D) of 66 mm, and a nominal ring width (B) of 8 mm. This configuration yields an effective cross-sectional wall thickness of 8.0 mm and an envelope ratio (D/d) of 1.32, delivering compact rigidity for OEM machinery housings.
Sourcing HRA5008 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for HRAU Series Crossed Roller Bearings.
