timken ENGINEERING WARNINGS and cautions selection guide Failure to observe the following warnings could create a risk of death or serious injury. Proper maintenance and handling practices are critical. Always follow installation instructions and maintain proper lubrication. Failure to follow these cautions may result in property damage. Use only new subassemblies for assembling chain strands. Do not use individual chain components and do not mix subassemblies from different chain manufacturers. Do not reuse sections from damaged chains. Damage from overloading or yielding may be present though...

ENGINEERING horsepower rating Horsepower Rating The horsepower rating in fig. 1 on page 7 is based on the following conditions: • Chains are operated under ordinary conditions. The ambient temperature range must be between 15° F and 140° F. They should not be used in an atmosphere in which abrasive dust or corrosive gas is present or where the humidity is high. • Two transmission shafts are in a horizontal position and the chains are properly installed. • Suggested lubrication system and oil are used. • Load does not change significantly during transmission. The service factors given in table...

Service Factors for Roller Chain Drives Type of Input Power Types of Driven Load Internal Combustion Engine with Hydraulic Drive Electric Drive Motor Internal Combustion Engine with Mechanical Drive Load Classifications Agitators – Pure liquid Smooth Load Conveyors – Uniformly loaded or fed (apron, assembly, belt, flight, oven, screw) Fans – Centrifugal and light, small diameter Machines – All types with uniform, non-reversing loads Clay-Working Machinery – Pug mills Moderate Shock Conveyors – Heavy duty and NOT uniformly loaded (apron, assembly, belt, flight,...

ENGINEERING horsepower rating Drive Selection Procedure Selection Example (1) Question 1: A conveyor with 50HP is driven by a 100 RPM electric motor. How should you select the chain and sprockets? Question 2: The number of revolutions for a drive is 500 RPM and the power to be transmitted is 13HP. The rpm is reduced to 125 (1 ⁄ 4). The center distance should be 11.00 in. with a space limitation of 19.00 in., and a uniform load. How should you select the chain and sprocket for this application? Answer: 1. Seek the service factor, 1.0, from table 2 on page 7. Power to be transmitted x service factor...

ENGINEERING horsepower rating Slow Speed Calculation Please consult your Timken Drives representative for applications 160 ft./min. or less. Selection of High Temperatures Our chains are made from heat-treated carbon steel. When exposed to high temperatures, the mechanical properties of the heat-treated chain components are impaired. 1. The hardness and, therefore, the wear resistance of pins and bushings is reduced. 2. At temperatures above 390° F, the rollers and plates may lose some of their hardness and strength. Standard roller chains can be used up to 500° F with the adjustments shown in...

ENGINEERING CORROSION-RESISTANT CHAIN PRODUCT horsepower tables Drives Roller Chain Dimensions and SELECTION GUIDE Corrosion-Resistant Chain PRODUCT SELECTION GUIDE Stainless Steel Material Selection Table 4. Materials of Component Parts 304 Stainless Steel Series (PS) The primary use of 304 stainless steel chains is in corrosive and/or high-temperature environments, which shorten the life of standard carbon steel roller chains. The 304 stainless steel chains give excellent resistance to corrosion and high temperatures. 304 stainless steel is generally considered non-magnetic. Link Plate 316...
