plastic conveyor rollers use high impact rigid PVC tubing and are a low cost alternative to stainless steel rollers. Plastic conveyor rollers are best suited to light weight gravity conveyor applications. XKTE specializes in manufacturing reinforced high quality ball bearing for conveyor idler rollers, good anti seizing properties in hostile dusty environment. The most important part of conveyor idler is bearing. It is unique design deep groove ball bearing for conveyor idler roller that meet all challenges: extremely different temperatures, low-speed, bulk materials handling, humidity, dust, dirt, as well as noise and vibration environments. Clearance:Open Type Deep groove ball bearings have internal clearance. 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 C3/C4 usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.TolerancesThe standard version of our single-row deep groove ball bearings has the tolerance class P0(designs with tighter tolerances available upon request) Conveyor idler Bearing usually need largeClearance such as C3/C4, Reinforce iron retainer or unique nylonretainer(superior anti-static and anti-sticking) and inner/Outer rings, Sealedtype, with good anti-sticking performance. While cannot use standard Bearing,they will cause big running resistance, brake and reduce lifetime of bearing. Feature of our conveyor idler roller bearing (Unique Design for Miningconveyor parts): 1. Grinding groove and super finished surfacetechnology 2. Thickening inner/outer rings, increases the service life 3. Reinforced Retainer and Stronger Rivet,unique Nylon Retainer Good toughness and strength, goodanti-stuck performance, constantly used industy environmentand underground environment. 4. Guaranteed by enough quality and quantitygrease 5. Good laser engraving continuous working for more than 30 thousandshours ensured. Details Of Thick Cage Super Finished Surface TechnologyDimensions 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 RingThe 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.
