Aerospace and Aircraft Bearings
Track rollers, airframe control, spherical, rod end, and instrument bearings from NHBB, Timken, Barden, Specline, and Aurora.
Jaco Aerospace stocks aircraft track rollers, airframe control bearings, spherical and rod end bearings, and instrument bearings from manufacturers including NHBB (New Hampshire Ball Bearings), Timken, Barden, Specline, and Aurora. Bearings are utilized in areas of an aircraft where inspection access is often limited. These bearings support actuation systems, engine accessories, landing gear, and control surfaces. Bearings can't be repaired in service if they fail.
While the bearing part number matters, the manufacturer's documentation, heat-treatment process, and material quality are just as important. Jaco Aerospace supplies bearings used by private industry, commercial fleet operators, military programs, and space programs. Materials range from carbon chrome steel to stainless steel, ceramic, and tool steel. Each material type has its own design, lubrication requirements, and coatings based on the environment in which the bearing will operate.
Bearing Types We Support
Airframe Control and Rod End Bearings
High-precision bearings for flight control linkages, actuation systems, and any application where a joint must move under load.
Spherical Bearings
Self-aligning bearings that handle misalignment and multi-axis movement in structural and control applications.
Aircraft Track Rollers
Designed specifically for flap track systems, slat mechanisms, and cargo systems where the roller repeatedly rolls on a machined surface.
Ball, Cylindrical Roller, and Needle Roller Bearings
Workhorse bearings used in all types of rotating equipment. Selection depends on the load direction, available radial space, and speed.
Thrust Bearings
Thrust bearings are designed to carry axial loads in gearboxes, accessory drive systems, and all types of rotating machinery with an axial load on the shaft.
Self-Lubricating and Journal Sleeve Bearings
Liner-based and plain bearings that require no lubrication after installation, ideal for locations where relubrication isn't practical.
Instrument and Miniature Bearings
Small-bore precision bearings for use in gyroscopes, sensors, actuators, and avionics hardware.
Cam Bearings
Followers used in mechanisms that convert rotational motion into linear motion.
Bearing Manufacturers We Support
We stock bearings manufactured by NHBB (New Hampshire Ball Bearings), Timken, Specline, Barden, Valley-Todeco, Galaxy, and Aurora. All bearings shipped from Jaco Aerospace include the documentation needed to meet your company's receiving inspection requirements and your customer's recordkeeping needs for material certification and lot history back to the original manufacturer.

Why Buy Aircraft Bearings from Jaco Aerospace
A bearing that arrives at your facility without complete documentation, or from a supply chain you can't trace back to the original manufacturer, can create issues during an audit. At Jaco Aerospace, we provide full traceability on every bearing we sell, and the documentation travels with the part.
Jaco Aerospace can meet both ends of the demand spectrum: individual bearings for repairs on one aircraft and large quantities for OEMs and MROs. We can ship orders anywhere in the world.
Choosing the Right Bearing
Bore size and load capacity narrow the options but typically don't provide enough information to make a final selection. Other factors, such as operating temperature, contamination exposure, whether relubrication will be possible after installation, and the required lubricant type, will determine the best option. A self-lubricated liner is appropriate for a sealed location that maintenance personnel will not access again for several years.
However, a standard greased bearing would be more appropriate if the location will be accessible for scheduled maintenance. If you are working from an OEM specification or seeking an authorized replacement for an existing part number, our staff can help you select the correct cross-reference rather than choosing based solely on dimensional matching.
