Bearing Puller (Internal) GEKO model 5901477182853 — internal bearing removal tool, set size (8)

The GEKO internal bearing puller is a mechanical extraction tool designed to remove internally fitted bearings without damaging surrounding housings. The tool engages from inside the bearing and applies controlled outward force to extract press-fit or seated bearings used in motors, gearboxes and other mechanical assemblies. The set includes a matched size (8) configuration intended for common internal bearing diameters where an internal engagement method is required.

Advantages

This internal bearing puller provides targeted engagement inside the bearing bore to minimize contact with the housing and reduce the risk of surface damage. Its mechanical design enables manual application of steady pulling force, allowing controlled extraction of press-fit components. The set size (8) configuration is prepared for use in workshop and maintenance environments where space is limited and internal access is necessary.

Suitable for

• Removing internally seated bearings from electric motors
• Extracting bearings from gearboxes and transmissions
• Maintenance and repair tasks on automotive assemblies with internal bearings
• Workshop and industrial maintenance where inside engagement is required

When it may not be suitable

This internal bearing puller is not intended for extracting bearings that are externally mounted or for applications where the bearing bore is severely corroded, deformed, or obstructed. In cases where the bearing is welded, fused, or otherwise permanently adhered to its seat, a press or heat treatment method may be necessary instead of manual pulling.

Key specifications

• Type: internal bearing puller (inside engagement)
• Set size: (8) — configured for a specific range of internal diameters
• Operation: mechanical/manual extraction
• Typical use: workshop and maintenance on motors, gearboxes, automotive assemblies

How to use

Select the appropriate jaws or collet configuration for the bearing inner diameter and insert the puller into the bearing bore so the gripping elements engage behind the inner race. Tighten the central forcing screw or apply the mechanical draw mechanism to create steady outward force, monitoring alignment to avoid tilting. Withdraw the bearing slowly while maintaining even pressure until the bearing clears the seat. Inspect both the bearing and housing for damage after removal.

What to consider before purchase

• Confirm the internal diameter range of the bearings you intend to remove matches the set size (8) configuration.
• Ensure there is sufficient internal access and clearance in the housing for inside engagement.
• Assess bearing condition — heavily corroded or deformed bearings may require alternative extraction methods.

Usage recommendations

Use steady, controlled force and proper alignment when extracting bearings to minimize housing damage. Clean the bore area before engagement and, if necessary, apply penetrating lubricant to ease removal. If excessive resistance is encountered, stop and evaluate whether a press or heating method is more appropriate.
