Material Information

INTECH Power-Core^TM rollers run more quietly than metal rollers, absorb vibration and shock, do not wear out the rail or track, and have low rolling resistance. They feature high load-bearing capacity and are suitable for a variety of applications requiring extended roller life.

INTECH Power-Core^TM composite material is an excellent bearing material and rollers can run directly on a hardened shaft. Lubrication is not required, however, oil and grease will not affect the roller material.

INTECH Power-Core^TM composite features a unique crystalline structure, remaining stable under varying conditions. It will not absorb moisture and is stress-free. The stress relaxation characteristics make the material uniquely suitable to carry static loads.

Precision bearing fit is maintained even under extreme ambient temperatures ranging from -40°F to +140°F. This stability translates into longer roller life in many tough applications.

Flat spot development in plastic or metal rollers means a premature end to roller life. Because of the physical properties of INTECH Power-Core material, the roller can sustain high static loads over prolonged periods of time without developing a permanent flat spot. The forces needed to initiate and maintain the rolling movement are calculated, as are the maximum load and time, to prevent permanent flat spot development.

INTECH Power-Core^TM track rollers do not require hardened rail surfaces. In high load applications steel 1020 CS rail is sufficient. Snap rollers are used with high quality bearings, for drive rollers a metal core is utilized to facilitate precision shaft attachment, such as press-fit, setscrew or keyway. An aluminum core can be specified for high-speed, reciprocating movement applications.

Responding to economic, competitive and environmental challenges and to customers' demands for assessing guide roller performance, our engineers, together with a leading university, developed an industry unique Roller Durability Calculation. The calculation results include:

• Maximum static and dynamic loads;
  
• Geometric distortion under load, i.e. flat development;
  
• Forces required to start rolling motion under load;
  
• Expected roller life in "Roll Overs" for a given load.
