Iron seals 6308 ZZ bearing is one types of Deep Groove Ball Bearing with double dust shields, compared with rubber sealed bearing, This kind of bearing can run in a high temperature environment, but its sealing performance is not as good as that of the rubber seals 2RS bearing.
With one shield (-Z) on one side or two shields (-2Z/ZZ) on both sides;
Shielded bearings are provided with non-contacting metal shields that protect against larger particles entering the bearing. They add no friction during operation and therefore do not generate heat build-up. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for shields.
Iron seals Bearing For Conveyor Idler usually need large clearance such as C3/C4, while can not use standard Bearing, they will cause big running resistance, brake and reduce lifetime of bearing. Bearing must be provided to ensure concentricity of the inner and outer raceway.
XKTE - Ball Bearings and Rolling Bearings in Conveyor Technology
XKTE is the specialist in rolling bearing technology for the mechanical application of continuous conveyors.
Super Finished Surface Technology
Dimensions such as the outer and inner diameters and the width are ground to micrometer (one-thousandth of a millimeter) precision, as is the groove, a key internal structure formed between the inner and outer rings in which balls run.
Thicker Inner & Outer Ring
The ring is the main part and the important part of the Idler Roller Bearing. Best idler Roller Bearing has deep groove ball, and large clearance. But deep groove doesn`t mean to dig the channel with a simple way of enlarge the steel ball. The thickness of the bearing is certain, so to get the ball big and the groove deep will shorten service life. Our XKTE bearing uses way of thickening ring to get the standard of deep groove and large clearance, improves the anti-stuck performance, and effectively increases the service life.
Grease selection of Roller bearing
Many customers ignore this most critical point. The thirty-thousands-hours operation is a very long term. This has to be guaranteed by enough quality and quantity grease. And this should also be taken into account of working in different seasons.
