This free flow chain can transport or accumulate materials on the chain continuously running.
The standard roller chain is fitted with side rollers for free flow to quickly carry or accumulate materials on them. Returnline layout is also simple and compact. Side rollers made of steel, plastics and rubber are available. Select them according to the kinds of transferred goods.
There are two types of formation: 1P Alternate side type (zigzag type) and 2P Both side type (parallel type)

Features of SOS Chain
Oil impregnation is not needed.

*   Clean operating environment can be maintained without contaminating the unit through oil impregnation. (*1)(*2)
*  Since NSF-H1 registered lubrication oil (applicable to any location where accidental contacts with foods are expected) is used, the chain can be safely used for food processing machinery. Products with industrial lubrication oil impregnated are also available. This chain is compatible with standard roller chains and accepts standard attachments.
*   Standard sprockets can be used for a multiple strand chain as well as a single strand chain.
*   The chain itself can be used in a low to high temperature range (-20ﾟC to 400ﾟC). (*3)

Note:
*1. Unless there are some problems in the use of stainless steel chain, lubricate it before using it.
*2. Do not use under complete oil-free condition.
*3. To bring out the best performance of its oil-impregnated bush, use this chain in the temperature range of -10ﾟC to 250ﾟC.
*The bush may wear out rapidly in a dusty environment. In addition, water splashing environment and higher temperatures make oil distill more easily from the oil-impregnated bush and reduce its life.

The special roller structure of this chain only requires approximately 1/2.5 velocity of chain compared to that of its pallet velocity. Therefore, this is the optimum choice for a line requiring quietness in running. In addition, since it has a excellent starting responsibility after accumulation compared to a common free flow chain, it is the best choice for an assembly line that repeats transportation and stagnation.
Select a roller material appropriate to the loading condition as for carrier chains.
There are several materials for roller available such as engineering plastic for low load (DP), conductive engineering plastic for low load (DPC), engineering plastic for middle load (DN), conductive engineering plastic for middle load (DNC), and steel for high load (HS).

To realize this product, the pins and rollers of SS chain have been replaced with those made of precipitation hardened stainless steel to improve its allowable load.
Its maximum allowable load is 1.5 times larger than SS chain. Please use this in case an SS chain will be short of allowable load.
Its corrosion-resistance is slightly lower than SS chain. Its operating temperature is -20ﾟC to +400ﾟC.
Note: This product has magnetism since it contains precipitation hardened stainless steel..
