Benefits of rovalrolls technology covers:

Cover uniformity is achieved through the accurate density control of every cover section, ensuring no variation in Shore D hardness.

Long lasting geometrical interference fit between cover and shaft is achieved through the regular and accurate measurement of the cotton material’s physical strength, and careful control of the inside diameter of the cotton discs.

For reliable injected covers, a sealing system is accurately engineered to adapt exactly to the design of the steel shaft, allowing for high pressure injection.

The specification and quality of the rovalrolls technology cover materials are precisely controlled utilising Roval's fully equipped research laboratory.
