Product Description Tapered roller bearings comprise solid inner and outer rings with tapered raceways and tapered rollers in a window cage. The bearings are in the form of: Standard Designs; Open Variants Matched in Pairs; Integral Designs Sealed on One Side JK0S. Open bearings are not self-retaining. As a result the inner ring with the rollers and the cage can be fitted separately from the outer ring. Metric and inch size bearings are available. Designs with a K in the designation have inch dimensions. For new designs however bearings in metric sizes should always be used in preference. Tapered roller bearings of series T7FC are supplied in X-life design. These bearings have improved surfaces a higher performance combination of material and heat treatment as well as an optimized contact geometry. This improves the friction behavior and increases the basic dynamic load rating. Under the same operating conditions a significant increase in basic rating life is achieved. For certain applications this means that a smaller bearing arrangement can be designed.
