NTRMS No-twist rod mill seals

NTRMSJames Walker is able to supply seals for no-twist rod mills by all major OEMs. Providing excellent value in service and performance for standard applications, our nitrile (NBR) material has served this application for many years, providing the performance required by plant engineers.

As running speeds have increased however, so have the demands placed upon the seal material and for some applications, a nitrile
rubber is no longer able to offer the optimum in performance therefore James Walker has developed a number of high performance hydrogenated nitrile (HNBR) options.

James Walker has supplied metal band retained seals for no-twist rod mills for over 25 years, working with OEMs to ensure the required levels of operational performance, accuracy and ease of fitting were achieved.

Through our detailed understanding of the work involved in the fitting of NTRM seals, we have developed and patented a solution that now reduces the effort and time required for seal replacement during maintenance, with the use of an innovative flexible retaining band.

In some instances our innovative flexible retaining band allows gearbox seals to be rapidly replaced in-situ, but even when gearboxes are removed to the workshop for overhaul, the fact that these seals can be replaced and correctly aligned more easily and quickly than traditional metal band retained versions without the need for specialist tools, provides maintenance and operational benefits.
