DSK rollers extra heavy duty
Other information about the product
PRECISMECA / RULMECA GROUP Heavy Duty Rollers are designed for heavy duty open mining applications. Thanks to the high quality machined parts and a non contacting multi-chamber labyrinth seal, the rollers run with a whisper. The high quality machining process is a guarantee for a long service life of the PRECISMECA rollers - 8 years in operation 24 hours a day is not a rarity.
Return rollers with rings should not be used as belt tensioning devices.
