Reduce Your Lead Times
Our manufacturing facility operates like a job shop, manufacturing specific to customers’ applications with low- to medium-production runs. We are able to manufacture product faster than major manufacturers through cellular manufacturing methods, streamlined supply chain, and 88+ years of knowledge and expertise. Each order is a priority.
Reduce Your Lead Spend
We strategically source materials and have minimized our manufacturing costs allowing us to offer the most competitive price in the industry. Additionally, we work directly with customers cutting out the middle man markup typically enjoyed by industrial distributors.
USA Made Expert Manufacturing
BSC has 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.
Maximum Life and Reduced Downtime
We tailor-make bearings specific to your application, whether it’s through enhanced materials, improved surface finishes, modified geometries, or installation / removal of features.
Uncompromised Quality
Our company is ISO 9001 certified. We have implemented process controls, in-process inspections, extensive software to track gage calibration, and tracking of material and heat treat certifications. We also have a coordinate measuring machine (measuring accuracy to 0.00005″) in a temperature-controlled room, 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.

BSC is not restricted to a certain grade of steel for bearing manufacturing, but instead accommodates the requirements for customers’ applications. This includes special tool steels for high-temperature stability as well as corrosion-resistant bearings.
All material certificates are filed in accordance with ISO requirements for future tracking and cross-referencing.
Our Manufacturing Process:
MACHINING
Raw material is received in either forged rings, tubing, bar stock, or centrifugally cast rings. BSC is equipped with modern CNC lathes and milling machines that soft machine components to a machine size, which allows for additional stock for distortion during the heat treat process. All operations are performed according to process sheets to keep processes consistent. Finished machined parts are identified and sent to heat treat.
HEAT TREATING
Most bearing components are hardened and tempered to provide either a through-hardened part with hardness range of 58 to 62 Rockwell C scale, or a case-carburized part with a relatively soft core and hard range.
Case carburized parts are less likely to fracture during impact or under load compared to through-hardened material.
High-carbon steels, such as 52100 and 440C, are used for through hardening and lower-carbon steels, such as 8620, 3310, and 9310 are used for case-carburized parts. There are several different criterial in the bearing application that determines material selection and heat-treat requirements.
GRINDING
After receipt of parts from heat treat, the parts are identified, inspected, and then ground to finish drawing size as per the prints. Generally, grinding takes place in three different phases, namely surface grinding, bore grinding, and OD grinding. Depending on the complexity of the parts, they may require special grinding equipment and fixturing. BSC has conventional bore and OD grinders, vertical grinders, and CNC grinders. All processes are recorded, inspected, and documented as per the process sheet.
ASSEMBLY & PACKAGING
Once all the components have passed dimensional and magnetic particle inspection, they are assembled, checking for running clearances, dipped in a rust preventative, wrapped in moisture-resistant wrap, and boxed for shipment. The boxes are labeled with the bearing number, date code, and other relative information depending on the bearing design.
