High precision FAG cylindrical roller bearings are used where very high accuracy is required.

Typical areas of application for these FAG bearings Surplus include machine tools and printing machinery. They are ideal as non-locating bearings since they allow unconstrained compensation of changes in length during rotational movement  between the rollers and raceways.

Due to their high accuracy with high radial rigidity, cylindrical roller bearings in a high precision variant are also used in addition to their application as non-locating bearings

wherehigh radial rigidity,high load carrying capacity ,high accuracy.is required of the bearing arrangement.

The standard series N10 of a single row design and NN30 of a double row design are a firmly established element of the FAG bearings Super Precision range, together with the series N19 and NNU49 of smaller cross-section for smaller centre  distances.

 The design of all FAG high precision cylindrical roller bearings is identified as standard, by accuracy class SP,tapered inner ring bore for adjustment of the radial internal clearance and preload (taper 1:12) by axial displacement on the tapered shaft seat (with a cylindrical inner ring bore if required) solid brass cage,radial internal clearance C1.

Due to the high surface quality of the ring raceways and rollers, FAG high precision cylindrical roller bearings are particularly suitable for grease lubrication.

New HIGH SPEED cylindrical roller bearings (N10..-HS_..),60% quicker at lower cost As a result of logical measures to reduce friction, Schaeffler Group Industrial has succeeded in developing an discount FAG bearings high precision cylindrical roller bearing with steel rollers that can achieve a significantly higher speed level than conventional cylindrical roller bearings.

In comparison with conventional high precision cylindrical roller bearings, the permissible speeds of the new N10..-HS cylindrical roller bearings with grease lubrication are up to 60% higher, while the increase with minimal oil quantity lubrication is up to 50%. The HIGH SPEED cylindrical roller bearing can thus exceed even the speeds achievable by hybrid bearings with a brass cage and its load carrying capacity is only slightly lower.

Operating conditions for FAG spherical roller bearings in vibratory machinery Vibratory screens used for grading materials and other vibratory machinery are among the machines subjected to the most severe stresses.

FAG roller bearings with Durotect CK coating in the bore In order to prevent friction corrosion between the bearing bore diameter and the shaft, FAG supplies spherical roller bearings with Durotect CK coated bores.

This ensures that the possibility of displacement (non-locating bearing function) between the bearing bore and shaft in response to thermal influences
is maintained over and beyond a long period of operation.The dimensions and tolerances of these bearings with Durotect CK coated bores comply with DIN/ISO dimensions and are interchangeable. FAG bearings distributor
