Pillow blocks are foot mounted units that are used to provide shaft support when the mounting surface is parallel to the shaft axis. The mounting holes are slotted for ease of mounting adjustment. KMS Plastic Pillow Blocks are made from engineering grade glass filled PBT polyester and are dimensionally interchangeable with conventional cast iron blocks. Polymer Pillow blocks are currently being used in many industries including food processing, bottling and packaging machines, chemical processing, and pool and marine applications. KMS Pillow blocks can be purchased with a variety of KMS insert bearings to best suit your specific application.
No Plating or Coating to Chip or Peel
Coated or plated cast iron housings can scratch, chip and peel. In fact, the very act of installing them causes the finish to be removed around the edges of the bolt holes beginning the process of corrosion. KMS housings are a solid base glass-filled PBT polymer which requires no coatings for corrosion protection.
Designed for Cleanliness
The KMS polymer surface is much more hygienic than cast iron. The rough surface of cast iron can harbor objectional dirt, mold, and bacteria. Additionally, the mounting surface, or the bottom of the block, is machined for flatness so that dirt and water do not lead to the formation of mold or bacteria.
Can Run Dry, Wet or Fully Submersed
The KMS block and bearing units are unique in that they can run fully submerged without lubrication. They can handle up to 120°f when submerged in liquids and even higher temperatures when they run dry. For alternative solutions for a higher temperature capability please contact KMS Bearings, Inc.
