CHAIN, BELT, AND SLIDING GUIDES Advantages of Murtfeldt chain guides Chain guides Where there is friction, there is wear. This is especially the case for applications where metallic materials are used. For example, for chains that run on metal guides, regular lubrication is absolutely vital. The aim is to achieve quiet, smooth running and long-term functional reliability. Murtfeldt chain guides protect your chains. They guarantee optimum running properties at the same time as extremely high wear resistance. The tried-and-tested Material ”S”® and the economical alternative ”S”®1000 have...

CONSTRUCTION WITH PLASTIC GUIDES Construction using thermoplastics requires careful consideration beforehand. The conditions of use have a direct influence on the material selection and design of the plastic guides. You should answer the following questions in advance: To what static and dynamic loads will the guide be exposed? To what environmental factors, such as chemicals, hot or cold water, steam, or contaminants will the material be exposed? In comparison with metallic materials, thermoplastics have a higher coefficient of linear thermal expansion. Calculation When calculating the...

Regardless of the fastening method chosen, you should design your plant so that the material can expand. The easiest and most efficient fastening method is to fasten the guide using our steel C profiles. The advantages of Murtfeldt steel C profiles Simple assembly/disassembly of the guide system Steel C profiles also act as stable fasteners and can be welded or screwed on as required. We recommend the use of DIN screws or special assembly using T-head bolts (see pages 8 - 9). Plastic profiles only need to be secured against being pushed out once Construction with Pl astic Guides / Steel C...

Single or varying chain/belt/cargo direction When expansion takes place, the plastic guide moves up in the opposite direction to the running/conveying direction. You should therefore make sure that sufficient space for the anticipated expansion is provided at the start of the plastic Plastic profile Elongation range Running direction -

FASTENING OF STEEL C PROFILES With T-head bolts T-head bolts provide a secure connection between your machine element and our C profiles. As a rule, a simplex connection is used. Duplex connections are available if desired. Our application technology department will be glad to advise you to ensure that you obtain the best implementation for your requirements. We can bore or punch individual hole patterns if you provide us with an appropriate drawing. For T-head bolt dimensions, see the following page.
