Quality Control.

Your Premier Source For USA Manufactured Bearings.

Quality Control: ISO 9001 Certificate

ISO 9001 certification is a globally recognized measure of quality control that assists both domestic and international customers alike to discern which manufacturers will provide reliable service. Our company is ISO 9001 certified, which means that we have implemented process controls, in-process inspections, and processes for the tracking of material and heat treatment certifications.

High Quality Equipment and Machinery

These methods of quality assurance are made possible through our use of state-of-the-art equipment, such as the extensive software we use to track gage calibration. BSC also has a coordinate measuring machine with a measuring accuracy to 0.00005. Located in a temperature-controlled room, this equipment is used for all in-process and final inspections of dimensions, roundness, concentricity, and taper. All material certificates are filed in accordance with ISO requirements for future tracking and cross-referencing.

USA Made: Expert Manufacturing

BSC has an uncompromising dedication to quality control, coupled with modern equipment, top-grade materials, performance-tested products, and the work of our highly skilled technicians. Our steel is locally sourced and all of BSC products are manufactured at our 88,000+ sq. ft. manufacturing facility in Pittsburgh, PA.

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.
