    Welcome to the Ball & Roller Bearing Division of Gwilliam Company, Inc.

    The Ball & Roller Bearing Division (formerly the Ball & Roller Bearing Company) has a prestigious history of manufacturing bearings in Connecticut for over 107 years.  We manufacture a complete line of ball thrust bearings, cylindrical roller thrust bearings,  cylindrical radial roller bearings,  and journal roller bearings.  In addition to our standard line of bearings, we provide design and manufacturing services for many “special” bearings built to our customers specifications.  

    Who We Serve

    We service both OEM and the industrial power transmission aftermarket, and market our products directly to manufacturers as well as through our nationwide system of distributors.  Diameters range from 1/2″ to 24″, in both English and Metric dimensions.  All of our bearings are made in our facility in Connecticut and comply with all ABMA, ABEC and RBEC specifications and tolerances.  All bearings are made using hardened and ground bearing steels, with machined bronze or steel used for rolling element retainers.

    US Approved Government Bearings Supplier

    We are an approved US Government bearing supplier and are fully compliant with all DFARS and Mil Spec requirements.  We proudly offer affordable bearings and assemblies to meet the unique requirements of the various service branches. These needs include everything from maintenance equipment to field artillery. We provide both standard and custom bearings, assemblies, and reverse engineering to the armed services.

    Loose Bearing and Sizing Ball Supplier

    We also can supply your loose bearing ball requirements.  These balls can be supplied in accordance with the applicable Mil Spec with chemical and physical certifications if required.  They are available in all grades, sizes and materials, including chrome steel, stainless steel, carbon steel, brass, bronze, tungsten carbide, aluminium, K-Monel, glass, plastic and ceramic.  We stock a large inventory of precision sizing balls, ranging in size from 1/64″ to over 1″ in diameter and everything in between, carried out to as many as 5 decimal places.  Most are available for immediate delivery.

    Why Choose Gwilliam?

    We pride ourselves with prompt delivery of precision, quality bearings.  Being a small manufacturer, we can be flexibile with our manufacturing schedule to provide you with the bearings you need within the time frame you require them.  We can offer you a level of service which you don’t usually receive from our larger competitors, such as shorter lead times, staggered deliveries, engineering and application advice, and no minimum order quantities.
