607 ZZ bearing
607 ZZ bearing refers to the radial ball, which are universal, not separable and consist of solid outer and inner rings, balls and separator. These bearings, having a simple construction, are reliable in operation and easy to maintain. Available in single and double row, in closed and open constructional design. Due to the nature of the manufacturing process, open bearings may have recesses in the outer ring for seals or caps. Due to the low friction torque, the deep groove ball bearings are suitable for high speeds.
Due to the geometry of the raceways and balls used as rolling elements, ball bearings can withstand axial loads in both directions, as well as radial loads.
Compensation of angular misalignments (self-establishment) of single row radial ball bearings is limited, so the installation of the bearings must be sufficiently accurate. The displacement of the rings can lead to adverse effects of the movement of the balls and will cause additional stress on the bearing, which will shorten its service life. In order to keep these loads low, only small angles of adjustment (depending on the load), namely, an average of 4 'to 10', are permissible. Due to their internal design, double-row radial ball bearings cannot be self-mounted. When using these bearings, therefore, distortions are not allowed.
Single row radial ball bearings are the most commonly used type of rolling bearings. They are produced in numerous sizes and various designs and are particularly economical.
Radial ball bearings with suffix 2Z are slotted on both sides and are suitable for high speeds, as well as lubricated with high-quality lubrication and lubricated for the entire period. They can be used from -30 ° C to +120 ° C.
In radial ball bearings without a separator material suffix, the separator is made of sheet steel. If the separator is made of brass, polyamide reinforced with fiberglass or other materials other than steel sheet, then the bearing designation should have a corresponding suffix, which is different for each manufacturer.
