Reduction by 50% in the tolerance range of the external diameter, concentrating the tolerance range in the center of N class, which ensures better precision control in the housing.
Reduction in the tolerance range of the internal diameter to the upper half of the N class tolerance range, which ensures proper tolerance for sliding adjustment on inner rings and, at the same time, reduces excessive sliding and friction.
The tolerance range of the radial internal clearance changed to 2/3 in the upper part of the specified tolerance, precisely controlling the load distribution and heat generation.
Presently, these suffixes are used to manufacture CAM type self-aligning roller bearings, which present:
Single part brass machined cage, with high mechanical strength and good wear resistance.
The roller races are displaced, always keeping a roller (race 1) at the center of two rollers (race 2) With that, it is possible to observe a larger number of rollers distributing the load, which enables increased load capacity.
There is a guide ring that minimizes the friction between the separator and the rolling elements, presenting reduced head generation and allowing increased speeds.
The rollers and lips present a special design to reduce heat generation and tension concentration that damage the bearing early.
