New Hampshire Ball Bearings, Inc. (NHBB) Precision Division in Chatsworth, California recently introduced the industry's first ultra-high speed bearing with anti-bacterial properties. Ball bearings are an integral part of all rotational cutting tools used in surgical practice, medical and dental offices. The antimicrobial properties of the element silver have been used for more than 100 years to control bacteria, mold, mildew and fungus in medical and food applications. According to recent studies, up to 4% of all post-surgery complications are associated with surgical tools contaminated with bacteria. NHBB Precision Division engineers have integrated antimicrobial silver plating into its patented Composite Metal Polymer Retainer. The silver plated machined polymer retainer has been primarily tested in bearings used for dental handpieces, with additional research and development on-going for medical devices. The test results confirm that this technology is unique in that it can extend the operational life of a medical or dental bearing, in addition to having a significant impact on the battle against hospital-related infections. Introducing the antimicrobial properties of silver into ultra-precision miniature and instrument bearings used in a dental or medical application can potentially arrest the spread of bacteria. According to Alan Paynter, NHBB Precision Division Sales Manager, "With our broad range of engineered solutions, including bearing construction types, proprietary retainer designs and an extensive offering of coatings and platings we can meet most application challenges." In addition to its anti-microbial and anti-bacterial properties, the composite metal polymer retainer increases the bearing operational life by up to 70% in any application requiring maintenance free and reliable operation in extreme environments. These applications are typically high speed with minimal lubrication and require repeated sterilization (autoclaving). The silver plated retainer
Products & Services
Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings.
Thrust bearings are designed for pure thrust loads, and can handle little or no radial load. The rolling element in a thrust bearing can be a ball, needle or roller.
Radial Ball Bearings
Radial ball bearings are friction reduction, rotation devices that carry loads radially around its axis. A subtype of ball bearings, they operate through the use of lubricated steel balls placed between two circular guides. They are frequently called deep-groove bearings.
Super Precision and Spindle Bearings
Super precision and spindle bearings are high-precision bearings that are designed for use in machine-tool spindles and other precision applications. Most super precision bearings and spindle bearings carry a high quality-rating such as ABEC-7 or ABEC-9, and run coolly and smoothly at high speeds.
Angular Contact Bearings
Angular contact bearings are designed so that a contact angle between the races and the balls is formed when the bearing is in use.
