Conveyor Support Roller Bearing 6205-2RS C3 have rubber dust seals on two sides of bearing and commonly use pressed steel cages. The function of rubber seals are to protect the bearing from contaminants, they are important to keep the bearing clean when you take it out of the packaging so you don't contaminate it just by handling it. The primary function of the seal is to protect the bearing from contaminants, it is important to keep the bearing clean when you take it out of the packaging so you don`t contaminate it just by handling it. Another function is, of course, is to make sure the bearing retains the lubricant. because of the rubber lip that`s making contact with the inner ring, we have the rubber rubbing on the inner ring of the bearing, increasing the friction in the bearing.
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.
Rubber seals Bearing For Conveyor Idler usually need large clearance such as C3/C4, Reinforce iron retainer or unique nylon retainer(superior anti-static and anti-sticking) and inner/Outer rings, Sealed type, with good anti-sticking performance. 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 race.
XKTE - Ball Bearings and Rolling Bearings in Conveyor Technology
XKTE is the specialist in rolling bearing technology for the mechanical application of continuous conveyors.
Feature of Rubber Sealed Deep Groove Ball Bearing:
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 Seals ball Bearing for Idler. 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.
