POBCO Guide Rails, Chain Guides and Linear Supports are normally made from white ULTRA-D® (UHMWPE), PLUS® (fluid lube-filled grey UHMWPE), and POBCO-B® Lube-Filled Hardwood. Many come complete with Stainless Steel, Steel, or Aluminum Supports.

These products are also available in Static-Reduced black Ultra-D, UV Stabilized black or natural Ultra-D, Acetal (Delrin®) for applications requiring a rigid plastic or in contact with a steam cleaning environment and Filled Teflons for high temperature (500°F±) applications.

POBCO anti-friction plastic profiles are available with 1/4" or 3/8" diameter 304 stainless steel and carbon steel rod encapsulated in the plastic, or are slid over 3/8" stainless steel or carbon steel rod. A MAJOR ADVANTAGE of the slid-fit plastic assembly is that the rod can be reused when the plastic is replaced. This is a MAJOR MONEY SAVER.

The larger guides do not always require the added stiffness and strength rendered by the stainless steel or steel rods. Solid Plastic or Lube-Filled Hardwood may be preferred. Stainless Steel or Steel guide rail connectors are used to hold guide rail ends together and for providing metal bottoms for welding purposes. Other rigid bottoms are available.

The advantage of the special POBCO-B HARDWOOD over most bearing-grade plastics is that it affords a MORE RIGID, DIMENSIONALLY STABLE material coupled with a material which is 100% LUBRICANT-FILLED to render a lower coefficient of friction and LONGER LIFE. Plastics sometimes lose their capacity to stay dimensionally stable under changes in temperature. The larger profile plastic shapes may also loose their capacity to stay straight along a linear path due to the lack of rigidity inherent in many plastics. Therefore for CHAIN and CABLE GUIDES and similar applications POBCO-B HARDWOOD should be seriously considered.

These Guide Rails can be affixed to Conveyor or linear supports by using the clips and connectors shown or they can be drilled and tapped to accommodate threaded bolts such as the 1/4" - 20 thread.

All POBCO Guide Profiles equipped with stainless steel & carbon steel or metal rod cores are protected under PATENT No. 4,932,517.
