Needle roller guide rails type NO consist of 2 hardened rails which are supported by an angular cage. As standard, the needles are held by an aluminium cage. The smaller diameter of the rollers and thereby more rollers, can absorb higher loads, instead of the type R.

The low friction coefficient of 0.003 is possible due to the roller bearings. Accessories such as end pieces, end screws and wipers can be found at “Options”.

Various special designs are available upon request,
please contact us.
