Maintenance Tools

Expert Tools.
From the Experts.

Bearings are a key precision component in any moving machinery and must be handled carefully to ensure they perform to their full potential. Bearings have to be correctly fitted, both onto a shaft and into a housing, as recommended by NSK in our technical catalogs. Consequently, fitting a bearing requires special tools and equipment: from safely heating components to safely applying appropriate forces to achieve assembly. Not observing these practices can lead to damage to a bearing or surrounding parts, premature failure and unnecessary maintenance costs.

NSK offers a complete range of specialist tools to ensure bearings are fitted and removed without damage. This is complemented by available NSK training courses that teach best practice in using these tools and help engineers to develop safe and efficient assembly procedures.
