Product Description

Troughing or carrying idler sets usually comprise between two and five individual idler rollers mounted into a common base, which is attached to the conveyor structure. Each idler roller in a 'set' comprises its own set of bearings, seals, shaft and outer shell as can be seen in the following section. Xinkaite Bearing is a professional belt conveyor roller bearing manufacturer enterprise, specialized in manufacturing bearings for the mining bulk material handling industry.

Iron Shielded Bearing

Sealed type: 

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.

Design characteristics:

Open Deep Groove Ball Bearing Feature

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.

Super Finished Surface

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.

Thicker Inner Outer Rings

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.
