Koyo, the bearing brand 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.

For further details about the Koyo JHS-3i Pillow Blocks, please consult the related flyer, which can be obtained here, or via your local Koyo office or Koyo distributor.

FAQ

What is an angular contact ball bearing?

An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. Ceramics such as silicon nitride are now regularly used in such applications due to their low density (40% of steel). These materials significantly reduce centrifugal force and function well in high temperature environments. They also tend to wear in a similar way to bearing steel—rather than cracking or shattering like glass or porcelain.

Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.
