Assembly Preservation & Packaging

Your Premier Source For USA Manufactured Bearings.

Bearing Assembly Preservation & Packaging

Once all bearing components have passed dimensional and magnetic-particle inspection, they are assembled, checked for running clearances, dipped in a rust preventative, wrapped in moisture-resistant wrap, and boxed for shipment. Explore these bearing assembly processes in-depth below and discover how BSC is equipped to serve your bearing manufacturing needs from start to finish.

Checking for Running Clearances for Bearing Assembly

One of the most important stages of bearing assembly and packaging is the process of checking for running clearances. This service requires specialized tooling, namely precision micrometers, that must be handled by highly trained professionals. At BSC, our team is not only capable of performing this assembly step with the utmost precision, but also with an efficiency that reduces overall assembly time.

Rust-Preventative Bearing Assembly Services

Whether due to the unwanted entry of water and corrosive elements during end-use or improper bearing lubricant, rust is a worrying type of damage that affects companies across countless industries. Bearing manufacturers can address this issue head-on by implementing rust-preventative measures during the bearing assembly process. BSC, in particular, uses a protective coating that allows our customers to benefit from long-lasting product life cycles and stocking needs.

Moisture-Resistant Wrap for Bearing Assembly

Just as rust-preventative measures work to protect bearings during their end-use, moisture-resistant wrap works to prevent unwanted moisture from causing rust to bearings as they ship from our facility to yours. BSC believes that the worth of a company is determined by how they manage the smallest details of their business, including the overlooked but important process of protective packaging. Because of this, our company is exacting when it comes to the quality of our moisture-resistant wraps and related packaging protections.


After Bearing Assembly: Shipping to Customers

Once the bearing assembly process and associated procedures are complete, the bearing orders are then boxed to be shipped to customers. The boxes are labeled with the bearing number, date code, and other relative information depending on the bearing design.
