NSK Corporation Ltd.: 0.3 TCR = 9% of Bearings, ball and roller, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

NSK Corporation Ltd. safety composite

NSK Corporation Ltd. scores strongest on total case rate (tcr) (safer than 96% of same-industry peers) and weakest on fatalities (safer than 50%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
