NHBB Launches High Temperature Liner Technology
December 8, 2014 (Laconia, NH): NHBB is pleased to announce the launch of a new, high temperature fabric liner technology, Vulkyn™ 650. This innovative fabric liner system for plain bushings and spherical bearings establishes a higher threshold for bearing performance within high temperature applications.
Vulkyn™ 650 raises the maximum operating temperature of NHBB's high temperature solutions by 25°F. As the suffix 650 suggests, the new liner solution provides reduced wear at 650°F of less than 0.006 in. after approximately 325,000 cycles. When tested at 570°F, the cycle count increases to 500,000 before liner wear reaches 0.006 in.
NHBB's innovative high temperature fabric liner technology is ideal for both military and commercial aero engine applications where bearings are exposed to sustained operating temperatures above 350°F. Good examples include engine mounts, oil cooler mounts, and variable stator vanes.
While longer bearing life under higher temperatures is the primary benefit, Vulkyn™ 650 is also designed to be eco-friendly. The compounds that make up the fabric and bonding agents currently comply with REACH, which is an important benefit to many of NHBB's customers who supply product to European OEM's.
NHBB's New Product Development Center (NPDC) has been working on the development of this patented technology for close to two years. While 650°F is an important milestone, the NPDC is committed to raising this maximum temperature even higher in the coming years.
