Pferdergonomics:
PFERDERGONOMICS recommends POLISTAR-TUBE to reduce vibration and noise produced during use and to improve comfort when working.
Recommendations for use:
For the best performance, use with a recommended peripheral speed of 3,000-4,000 SFPM.
Recommendations for use 1:
Select the POLISTAR diameter based on the respective pipe's inner diameter: Dia. 3-1/2" for inner pipe dia. 2-1/4" - 2-3/8
Recommendations for use 2:
Grit size 60 designed for roughness value 1.0-1.3 μm Ra.
Safety notes:
For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
Manufactured By:
Pferd Inc.
Other Details
Achieves very fine surface quality grades of up to 8 μin (0.2 μm).
Conforms to contours due to high flexibility.
Stainless steel rivets prevent contamination of stainless steel (INOX) workpieces.
