Product Announcement from USA Tolerance Rings
Save money and time on the maintenance and repair of worn or oversized housings on motors, pumps, pulleys, and most any rotating device. USA Tolerance Rings are corrugated compression sleeves, specifically designed to assemble the outer ring of a ball bearing into a housing.
It was common practice to throw away products that were simply worn out or products that may have been made oversized in the production process. The increased cost of materials has made many customers take a hard look at refurbishing and repair as a way to reduce costs. The most common application is to use tolerance rings in worn bearing housing bores. Reworking a bearing housing bore is a simple four step process. 1.) Select the Tolerance Ring part number by matching it to the existing ball bearing part number. (See Chart) 2.) Machine the housing bore to the recommended size. 3.) Insert the Tolerance Ring into the housing bore (See instruction sheet) 4.) Press bearing into the tolerance ring and housing assembly. (See instruction sheet)
Common repair items are electric motors, alternators, pumps, compressors, and fans. These same applications may use tolerance rings in original design to reduce noise, limit vibration, and to accommodate temperature changes. Tolerance Rings allow for easy of assembly and disassembly making them good choices when machinery requires disassembly for periodic maintenance.
