Rubber sealed deep groove ball bearings have rubber seals installed on one or both sides and are pre-lubricated with grease. These bearings often Also, snap rings are sometimes used on the outside edge. rubber sealed deep groove ball bearings with their simple design, high resistance and low-maintenance, while many different retainers are available, pressed steel cages are most commonly used.
Sealed type:
With one seal (-RS) on one side or two seals (-2RS) on both sides. Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.
XKTE - Ball Bearings and Rolling Bearings in Conveyor Technology
XKTE is the specialist in rolling bearing technology for the mechanical application of continuous conveyors.
Clearance:
Select the large bearing clearance (ie. C3, C4) here is very important. It compensates for shaft deflections as well as temperature differentials. This provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. Large clearance usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.
Design Characteristic:
Our sealed type deep groove ball bearings use unique design steel cage, The inner/outer rings and Retainer(cage) are thicker compare with the common bearings, stronger rivet, which consist more reliable structure. strong impact and heavy load with Grinding groove and super finished surface technology. to offer the long life under extreme harsh environment.
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.
