Stainless Steel Roller Chain
316 NS Series The 316 NS Series provides maximum corrosion resistance and temperature resistance, with virtually no magnetic permeability. These are critical factors in many applications involving electronics or the production of steel. 600 AS Series AS Series chain was developed for the most demanding applications. With precipitation-hardened round parts, the 600 AS Series combines high load capacity and high corrosion resistance. Of all the stainless steel chains offered by U.S. Tsubaki, AS Series has the highest load capacity. Our standard attachment chains supplied from stock are manufactured to this specification.
U.S. Tsubaki offers the most complete line of stainless steel roller chain in the industry. In fact, with U.S. Tsubaki stainless steel roller chain, plus our stainless steel attachments, sprockets, and POWER-LOCK ® , you can create a reliable stainless steel system that withstands extreme temperatures and corrosive conditions. Three Kinds of Stainless Steel to Meet Every Application U.S. Tsubaki has four different types of stainless steel roller chains in stock for immediate delivery. You get greater selection and improved performance. Each type has unique characteristics to address your specific needs. 304 SS Series SS Series chains are made completely of 304 stainless steel. They offer excellent resistance to corrosion and extreme temperatures. The 304 SS Series is ideal for environments that require tougher resistance to acids and alkali.

• Chain diagrams are drawn with S-rollers although R-rollers are also available with the same attachment dimensions. Attachments are shown at every link. • C2040~C2060H connecting links are clip type; C2080H~C2160H are cottered type, GK-1 attachment connecting links are cottered type. • All links other than connecting links, with or without attachments, are riveted type.

STAINLESS STEEL CHAIN SELECTION
General selection is based on bearing pressure between the pin and bushing. Anti-corrosive roller chains are normally intended to be used at slow speeds without lubrication. Chain selection should be made based on the bearing pressure shown below.

Stainless Steel Sprockets
Long-Wearing Sprockets for Special Environments When ordering stainless steel chains and attachments, \consider stainless steel sprockets. Make your entire operation corrosion resistant.
Our standard stainless steel sprockets are specially constructed for food applications but can be used in any corrosive environment. We start with a thicker plate and weld on the hub. Then we lathe the sprocket, machining all sides to remove pits and marks. The smooth finish means food and bacteria won’t gather. For corrosive environments that do not involve food, we offer made-to-order stainless steel sprockets without the lathing step. That reduces your cost and yet maintains high-quality corrosion resistance for your operation.
Keep your lines running at peak performance with a complete stainless steel system— roller chains, attachments, sprockets, and POWER-LOCK ® — from U.S. Tsubaki.
All stainless steel sprockets from U.S. Tsubaki are made using high-quality 304 SS stainless steel. This provides excellent resistance to food and chemicals, including acids and alkali, as well as to extreme temperatures.
Consult with U.S. Tsubaki about your application, and we’ll suggest the most cost-effective sprockets to keep your lines running.
Stainless steel sprockets from U.S. Tsubaki are available for food grade and nonfood grade applications.

Stainless Steel Power-Lock ®
Enter the “Keyless” Society
Easy and Precise Positioning POWER-LOCK offers 360º angular adjustment and is excellent for indexing tables, cam mechanisms, gear drives, and double strand conveyor sprockets. Easy Assembly and Disassembly POWER-LOCK can be assembled and disassembled frequently, so maintenance or replacement of worn parts is simple and easy as compared to other methods (key and keyway), spline, shrink or press fits, and welding). Increased Shaft Strength By using the POWER-LOCK, no metal needs to be removed from the shaft (such as cutting of a keyway). The strength of the shaft can be kept as its original diameter. This saving is especially applicable on hollow-shaft applications.
Stainless steel POWER-LOCK solves your problems. Eliminate backlash damage to keyways from heavy loads. POWER-LOCK fits tightly without backlash around the shaft/hub and is not affected by load reversals.
End your high machining expenses for long shaft keyways, splined shafts, threads, grooves, and steps. POWER-LOCK provides exact, slip-free location.
Stop shrink and press fits. POWER-LOCK simplifies installation and removal.
Easy-to-install POWER-LOCK slides into position and offers a keyless, shaft-hub lock that will simultaneously handle both high torque and thrust while increasing shaft strength.
Eliminates Costly Machining There is no need for time-consuming machining of keyways. The POWER-LOCK offers substantial savings on long, heavy shafts.
POWER-LOCK requires only one tool for easy assembly. It is ideal for locking in large or small sprockets, gears, pulleys, timing cams, and rollers. Best of all, POWER-LOCK is in stock for immediate shipment.
Features and Applications
Resistance to Corrosion and Extreme Temperature All component parts are made of high-quality stainless steel. The inner and outer ring are SUS304, all other parts are SUS630. You get outstanding resistance to corrosive chemicals, including acids and alkalis, as well as excellent performance in extreme temperatures. High Durability Against Reversing or Impacting Loads The POWER-LOCK connection is not affected by tortional load reversal or impact, which damages the key and keyway connection. The U.S. Tsubaki POWER-LOCK fits tightly around the shaft/hub and is free of backlash.

CONSTRUCTION
The POWER-LOCK ® is composed of five parts: taper ring (A), taper ring (B), outer ring, inner ring, and locking bolts. Locking is achieved by tightening the bolts.
CONNECTING PRINCIPLE
Taper rings (A) and (B) fit perfectly with the tapered inner and outer rings. By tightening the locking bolts, taper rings (A) and (B) generate clamping pressures (P’ and P) against the outer and inner rings to produce the frictional force to join the shaft and hub. A slit is provided on the circumference of the outer and inner rings to prevent reduction of the clamping force.
