Description

Carries radial loads within a compact drawn cup design, with the outer ring formed as a thin-wall shell and needle rollers running directly against the shaft journal, which must be hardened and ground to serve as the inner raceway. Outside diameter is 8.0 mm, width 8.0 mm, net mass 1.4 g. Limiting speed reaches 42500 1/min, with a reference speed of 44500 1/min. The open-end construction has no closure at either side, so the bearing is unsealed and relies on external provisions for lubricant retention and contamination protection. Without integrated sealing, grease or oil must be supplied and maintained through the housing design, and axial space savings from the thin cup wall come at the cost of needing a properly finished shaft surface to carry the rolling contact load.
