Koyo introduces new JHS-3i Pillow Blocks
Koyo Bearings, a division of JTEKT Corporation, is introducing its new range of “JHS-3i” high performance Pillow Blocks. With a legacy of Quality and Performance, Koyo Ball Bearing Units have been known to be the most reliable products when it comes to accuracy and load resistance. The new generation of JHS-3i Pillow Blocks introduces further enhancements in the performance through improvements in the housing, sealing and the applied grease. The first improvement is realized in the housing design which now has a flat bottom face which secures a more accurate and firm mounting of the pillow block on the frame, resulting in better rigidity and the elimination of vibrations.
The second improvement is realized through an improved seal design with an inwards facing lip which allows grease to flow back towards the balls and raceway during operation, thereby improving lubrication performance and extending bearing life.
The third improvement is in the newly applied high quality Lithium Complex grease providing several improvements, including a wider allowable temperature and speed range, resistance against water contamination, vibration and high pressure, as well as heavy- & shock loads.
To summarize: the Koyo JHS-3i Pillow Blocks provide a better performance and longer bearing life under a variety of high demanding operating conditions.
