Jena Tec MF option linear guides keep going and going...........

Expensive lubrication systems become a thing of the past and for machines without lubrication, Jena Tec's SBC MF series linear rail option extends the life and performance of your linear system by a significant factor.

The MF Lubricating Seal now offers longer life for SBC Linear Rail Systems, eliminating the necessity for periodical greasing. The MF Unit contains high quality ,grease filled fiber seals which will guarantee total surface lubrication and long maintenance free bearing life. The polymer housing containing the surface contact seals are tolerance matched to the guide rail to ensure perfect sealing and smooth motion.

MF Seal Units are grease filled and the lubricant is contained , spread and absorbed by the fiber seals. Using grease rather than oil ensures that the lubricant is retained within the MF seal units for a much longer working life than oil would remain. The grease used would be compatible with most standard industrial grades recommended for use in bearing blocks and provides excellent thermal stability and water proofing characteristics.

Tests conducted by SBC show a clear advantage of MF type seals, despite a modest increase in overall length through the slim line design of the fiber seal housing. Results show that for a standard theoretical distance life time calculation of a heavy pre-loaded guide block that the distance for an MF type under heavy load can be increased by 40% up to a 1000Km with no sign of degradation or wear affecting performance or accuracy. For light pre-loads the life extension can be up to a factor of 10 times. Even then replenishment with new MF end caps is a very simple straightforward procedure to give a further period of un-interrupted service.
