Frequently Asked Questions about HRE2008 HRE Series Crossed Roller Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

Built for demanding industrial environments, the HRE2008 HRE Series Crossed Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
When fitting HRE2008 over a 20 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
For international ocean and air freight, CHG Bearing packs HRE2008 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
To ensure optimum performance of CHG Bearing HRE2008 HRE Series Crossed Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 20 mm bore. For the 36 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
