Introduction
Gimbal bearings play a crucial role in various industries, including aerospace, defense, and manufacturing. These bearings enable smooth and precise movement in rotating assemblies. To ensure optimal performance and longevity, proper maintenance and repair are essential. One indispensable tool for servicing gimbal bearings is the gimbal bearing puller.
What is a Gimbal Bearing Puller?
A gimbal bearing puller is a specialized tool designed to remove gimbal bearings from their housings safely and efficiently. It comprises a threaded spindle, a bearing puller head, and various attachments. The puller head is designed to fit snugly around the outer race of the bearing, while the threaded spindle applies controlled force to extract the bearing.
Why Does Gimbal Bearing Removal Matter?
Gimbal bearings are precision components that require meticulous handling to prevent damage. Improper removal techniques can mar the bearing surface, shorten its lifespan, and compromise the integrity of the assembly. Using a dedicated gimbal bearing puller ensures a safe and controlled removal process.

Types of Gimbal Bearing Pullers
Various types of gimbal bearing pullers cater to different bearing sizes and configurations.
Puller Type | Application |
---|---|
Internal | For removing bearings with an interference fit on the inner race |
External | For extracting bearings with a press fit on the outer race |
Two-Jaw | Compact and suitable for smaller bearings |
Three-Jaw | Provides a wider contact area for larger bearings |
Hydraulic | Offers higher force capacity for stubborn bearings |
Manual | Economical for occasional use |
How to Choose the Right Gimbal Bearing Puller
Selecting the appropriate gimbal bearing puller is crucial for effective bearing removal.
1. Bearing size: Determine the diameter of the bearing to be removed.
2. Bearing type: Identify if the bearing is an internal or external fit.
3. Puller capacity: Ensure the puller has a rated capacity sufficient to extract the bearing safely.
4. Attachment compatibility: Verify the availability of attachments for the specific bearing type and size.
5. Ease of use: Consider the accessibility of the bearing and select a puller that provides adequate clearance.
Step-by-Step Guide to Using a Gimbal Bearing Puller
1. Preparation:
- Inspect the puller and ensure it is in good working condition.
- Clean the bearing and its housing thoroughly.
- Remove any debris or obstructions around the bearing.
2. Assembly:
- Attach the appropriate bearing puller head to the threaded spindle.
- Select and install any necessary attachments.
3. Placement:
- Position the puller head over the bearing, ensuring it is centered.
- Tighten the puller head to secure it firmly.
4. Extraction:
- Gradually increase the applied force by rotating the threaded spindle.
- Maintain steady and controlled pressure until the bearing is extracted.
- Remove the puller head and attachments.
5. Inspection:
- Inspect the bearing and housing for any damage.
- If necessary, clean and lubricate the bearing before reinstallation.
