INA Needle Roller Bearings
Cutaway of a Needle Roller Bearing
Needle roller bearings have a long track record as proven machine elements for the design of radially compact bearing arrangements with very high load-carrying capacity. In X-life configuration, they now have an up to 50 % longer service life.
INA Industrial Ball Bearings
National Precision Bearing services the INA industrial ball bearing offer. INA products cover Angular Contact Ball Bearings, Deep Groove Ball Bearings, Four-point contact ball bearings, Self-aligning ball bearings, spindle bearings, and more.
INA/FAG Cylindrical Roller Bearings
Single-row cylindrical roller bearings with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, and the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling. Cylindrical roller bearings can be supplied with or without a cage.

There is nothing that cannot be improved. We developed the TB roller to significantly increase bearing operating life under an axial load. TB as in TorusBallig (torus shaped). The special curvature of the end faces of this roller enables loads to be distributed across a significantly greater surface area. The curved roller end face increases the size of the contact surface and thus significantly reduces the contact pressure.
INA Plain Bearings, Maintenance and Maintenance Free Steel and Bronze Plain Bearings
Plain bearing and rod end designs that require maintenance with steel/steel and steel/bronze material pairs are easy to maintain, cost effective, and excellently suited to alternating loads. Plain bushes, washers, and strips employ the low-maintenance metal-polymer composite E50. The sliding layer features lubricant pockets, which means that an initial lubrication is sufficient in most cases.
INA Maintenance Free Plain Bearings
Schaeffler offers a comprehensive catalog of maintenance-free plain bearings. Innovative plain bearing materials are used here, such as ELGOGLIDE, ELGOTEX, and the metal-polymer composite E40. These PTFE plain bearing materials enable ultra-low coefficients of friction for spherical plain bearings and rod ends as well as bushes, washers and strips while ensuring low wear and very long life cycles. Maintenance-free plain bearings considerably reduce lubricant and maintenance costs as they do not require any oil or grease while also being very environmentally friendly.
