These bearings consist of a thin walled, drawn cup outer ring that serves as the raceway for the cage guided needle rollers. Despite their lightweight design, they offer high load carrying capacity, precise concentricity and compact dimensions, making them ideal for applications with limited installation space.
Needle sleeves and needle bushes do not require a separate inner ring if the shaft is ground and hardened to serve as the raceway. Their simple installation, low weight and high cost efficiency make them a reliable choice for gearboxes, electric motors and general machinery applications.
