needle roller bearings

Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They’re designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings.

Diverse types of needle bearings are available in a wide variety of sizes and tolerances, for a multitude of applications.
Needle roller and cage assemblies are offered in single or double row, solid or split cage, metric and inch sizes; as well as in connecting rod bearings for special applications.
Single and double row bearings are available with or without ribs, and with or without inner rings.
Thrust bearings are offered in single row roller and cage assemblies.
Yoke and stud type track rollers are also available.
