Aerospace Bearing Tools
What Are Aerospace Bearing Tools?
Aerospace bearing tools are precision tools for installing, swaging, removing, and testing aircraft bearings. Built to NAS0331 industry standards, they form, retain, and verify bearings in their housings without damage. We supply these tools for aircraft maintenance, repair, and overhaul work, with fast lead times for aircraft on ground situations where every hour counts.
At The Bearing Specialists, we supply aerospace bearing tools for bearing removal, installation, and testing. Our tools meet NAS0331 standards and comply with the specifications of leading aerospace bearing manufacturers and MRO facilities. We understand that time in the industry for aerospace bearing tools, ensuring UK customers from Crawley, get the quality tools they need when they need them.
Aerospace Bearing Tool Solutions We Deliver
- Installation tools that place bearings evenly and concentrically within their housings for correct retention and long service life.
- Tri-roller swaging tools, in drill press or portable styles, that form the bearing V-groove into the housing chamfer for a precise, repeatable mechanical lock.
- Cutting tools that cut the bearing V-groove cleanly so worn bearings come out without damaging the reusable housing.
- Testing tools for breakaway torque, swivel torque, and proof load measurement, supplied with electronics, a DTI, load cell, and digital display.
- Specialised retention tools including ball swaging, segment staking, reverse tri-roller, and sleeve swaging tools for bearings without V grooves.
- Custom tooling designed and built by our engineers for tight access and unusual aerospace applications.
Our Aerospace Bearing Tools Services
Proper alignment is crucial for effective bearing retention. Our installation Aerospace Bearing Tools ensure even and concentric placement of bearings within their housings. This precision is essential for optimal performance and longevity of the bearing assembly.
We offer two distinct methods for bearing retention, ensuring the integrity of the bearing swaging process:
- Tri-roller swaging tools: Available in drill press or portable styles, these tools gradually form the V-groove of the bearing into the housing chamfer. This is considered the most effective bearing swaging process for products sourced from a high-end aerospace bearings manufacturer, as it ensures a precise, repeatable mechanical lock.
- Staking: Using "anvil" tools in a hydraulic press, this method is suitable for large production runs but requires careful monitoring to maintain consistency compared to a roller-based bearing swaging process.
Our drill press and portable cutting tools precisely cut the bearing's V groove, allowing for removal without damaging the housing. This careful approach ensures that the housing can be reused, a standard requirement in the aerospace bearings manufacturer and repair industry.
We provide Aerospace Bearing Tools for various bearing tests:
- Torque testing: Measures the torque required to rotate the inner ball of the bearing. This can be either a breakaway torque or swivel torque test, providing crucial data on bearing performance.
- Proof loading: Measures the axial movement of the bearing under a known load. Our proof load tools are supplied with electronics, a DTI, load cell, and digital display, allowing for precise measurements of bearing displacement under specific loads.
- Housing over bearing tools: For bearings without V grooves, we offer a range of tools including ball swaging tools, segment staking tools, and reverse tri-roller tools. These specialized tools ensure proper retention for non-standard bearing configurations.
- Bearing sleeve swaging tools: U roller or flat roller tools for swaging non-grooved bearings within sleeves. These tools effectively form the sleeve over both the housing and bearing, ensuring proper retention.
How Do You Swage and Retain an Aerospace Bearing?
Bearing retention comes down to two methods. Tri-roller swaging tools, available in drill press or portable styles, gradually form the V-groove of the bearing into the housing chamfer. This is the most effective approach because it produces a precise, repeatable mechanical lock. Staking uses anvil tools in a hydraulic press and suits large production runs, but it needs careful monitoring to hold consistency against a roller based process. Our staking and swaging tools cover both routes.
How Do You Remove a Bearing Without Damaging the Housing?
Removal starts at the V-groove. Our drill press and portable cutting tools cut the bearing V-groove precisely so the bearing releases without harming the housing. Because the housing stays intact, it can be reused, which is a standard requirement across aerospace bearing repair work.
How Do You Test an Aerospace Bearing?
Two tests confirm a bearing performs correctly. Torque testing measures the torque needed to rotate the inner ball, as either a breakaway or swivel torque test, giving clear performance data. Proof loading measures axial movement under a known load. Our proof load and test tools ship with electronics, a DTI, load cell, and digital display for accurate displacement readings.
What Standards Do Aerospace Bearing Tools Meet?
Our aerospace bearing tools are built to NAS0331 industry standards and comply with major aircraft manufacturer process specifications, including Airbus AIPS 03-03-021, Boeing BAC5435, and Bombardier BAPS 175-004. We track current industry standards and can confirm compliance with any specific process specification you work to. Tell us the requirement and we will match or exceed it.

Frequently Asked Questions About Aerospace Bearing Tools
Swaging forms the bearing into its housing to lock it in place. Tri-roller swaging tools roll the bearing V-groove into the housing chamfer for a precise, repeatable mechanical lock, while staking uses anvil tools in a hydraulic press for larger production runs.
