6306H 72 mm 30 mm 19 mm Frequently Asked Questions about 6306H Metric Stainless Steel Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 6306H is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 30 mm) and steep thermal gradients between inner and outer rings.
Yes, 100% of 6306H Metric Stainless Steel Deep Groove Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
