Combined needle bearings, such as type RAX and its derivatives, are designed to simultaneously support both radial and axial loads. These bearings consist of a needle thrust bearing (or roller thrust bearing) and a needle cage, all retained within a common outer ring.
They form an integral unit, making storage, handling, and installation easier. Their high radial and axial load capacities, combined with their compact size, offer cost-effective solutions. Calculations for combined bearings are performed by separately considering the axial and radial components, without converting the axial load into an equivalent radial load.
These bearings feature a thrust plate and an outer ring that are machined separately and joined by a strong metal insert. This design prevents localized stresses and weaknesses between the two components, thereby reducing the risk of damage during mounting or operation.
These bearings include an integrated thrust plate, which is retained by a steel ring mounted on the thrust plate. This design provides better protection against dust and metal particles, making them suitable for use in the spindles of drilling machines.
Variations: Locking devices include eccentric locking collars and set-screw locking collars. Options for the inner ring include extensions on both sides, extensions on one side only, and bearings with a cylindrical outer diameter.
