NHBB has developed a wear sensor for the INVINSYS® brand of pitch link control bearings that enables helicopter maintenance personnel to easily and quickly determine the operating status of these flight-critical bearings using a wireless scanner. The added value created by NHBB’s patented wear sensor further establishes the INVINSYS brand as the leading bearing innovation within helicopter… Read more
NHBB’s Vulkyn® brand of high-temperature fabric liner performs better than NHBB first reported. Last year, NHBB announced that Vulkyn raised the maximum operating temperature of NHBB's high-temperature self-lubricating liners by 25°F.
Additional testing at higher temperatures has confirmed that it’s actually an increase of 75°F. When tested to 700°F, Vulkyn exhibits 0.006 inches of… Read more
NHBB has developed and launched four new versions of the Oscimax® brand of machineable self-lubricating liner technology, which, along with the original version, Oscimax XT, now covers the full range of friction and life requirements for NHBB’s aerospace customers. The four new versions include two low friction options (Oscimax XY and XZ), a specific formulation for landing gear applications (… Read more

Vulkyn® 650 is NHBB's newest high-temperature fabric liner technology. This innovative fabric liner system for plain bushings and spherical bearings establishes a higher threshold for bearing performance within high-temperature applications.
As the suffix 650 suggests, the new liner solution provides reduced wear of less than 0.006 inches at 650°F after approximately 325,000 cycles.… Read more
New Hampshire Ball Bearings, Inc. (NHBB) has developed the industry's first self-lubricating liner system to qualify for the new performance threshold of 100,000 cycles for spherical bearing life, established by industry-standard AS81820 Type 'A.' The liner utilizes PTFE to provide the long life and wear-resistant surface required by the Type ‘A’ spherical bearings.
Spherical bearings… Read more
Astro Engineers Design Cost Effective Retrofit Solution of Link Assembly for High Temperature Application
A customer recently approached Astro for help in solving a bearing wear problem in an existing application. A link assembly was wearing out long before its rated life and well within the warranty period. With hundreds of engines in service, and each containing a set of six links, replacement costs were mounting. The customer was desperate to solve the problem quickly and economically.… Read more
