New FAG high performance spherical roller bearings from Schaeffler Australia feature Durotect® CK coating in the bore to offer 70 per cent better lifespan when withstanding the extreme stresses of the exciter units of vibratory machinery.
The FAG T41D series of Special Spherical Roller Bearings – featuring Schaeffler X-Life quality standards and the hard chromium Durotect® CK premium performance coating – are designed to curtail fretting corrosion of shafts and journal wear, setting new industry benchmarks throughout Australia and New Zealand for longer service life.
Features of the FAG T41D series and its Durotect® CK protection include:
Special T41 dimensional tolerances apply to the bearings’ inner and outer rings, meaning optimum interference fit can be achieved on the outer ring and sliding fit on the inner ring. The bearings’ C4 radial internal clearance prevents harmful radial preloading.Durotect® CK plating on the inner bore not only prevents fretting corrosion of the shaft, but also reduces cross-location of bearings and gives improved load distribution because of unhindered thermal expansion of the shaft X-Life features include Bainite heat treatment, giving improved productivity through temperature stability up to 200C; surface hardened cage with high wear resistance; and cage guidance by the outer ring to accommodate centrifugal forces. X-Life’s tighter inside and outside diameter dimensional tolerances offer better control of fit in both housing and shaft Combining the benefits of the T41D design with the Durotect® CK performance coating means operators can function more efficiently and achieve the lowest total cost of ownership (TCO) while delivering a higher level of performance and machine reliability.
