Bearing Puller (Inertia) YATO YT-25390 — manual inertia-style bearing remover

The YATO YT-25390 inertia bearing puller is a manual tool engineered to remove press-fit bearings, rollers and bushings by converting manual force into controlled inertial impacts. Designed for situations where powered extraction tools are impractical or unavailable, this inertia-style remover enables dislodging tight-fitting components from shafts and housings using a simple mechanical striking action. The construction is intended for workshop and maintenance environments that require a compact, hand-operated solution for bearing extraction tasks.

Advantages

The inertia bearing puller provides a mechanical method of extraction that reduces the need for heating or hydraulic presses. Its manual inertia action offers repeatable impact energy while limiting the risk of direct over-torquing the shaft. The tool's compact design allows access in confined spaces and supports a variety of common bearing and bushing removal scenarios without reliance on power sources.

Suitable for

• Removing press-fit bearings from shafts
• Extracting rollers and bushings from housings
• Workshop and maintenance bearing servicing
• Field repairs where power tools are not available

Key specifications

• Operation type: manual inertia impact remover
• Intended use: extraction of press-fit bearings, rollers and bushings
• Application environments: workshop, maintenance, field service
• Design feature: compact hand-held body for confined access

How to use

Position the puller so that its engaging surfaces seat firmly against the inner or outer ring (as appropriate) of the bearing or the component to be removed, ensuring the tool is aligned coaxially with the shaft. Secure any necessary jaws or adapters and support surrounding assemblies to prevent damage. Apply a series of controlled manual strikes to the inertia mechanism or striking cap; the stored inertial energy transfers to the puller, producing short impact impulses that dislodge the pressed component. Check progress frequently and stop if resistance changes unexpectedly.

Usage recommendations

Always verify correct alignment before applying impacts and protect adjacent components with appropriate supports or shields. Use eye protection and gloves during operation. If the component does not move after several measured impacts, reassess the setup or consider alternative extraction methods to avoid damage.
