Dust-proof Carrying Idler Roller with White Covers and Blue Belt
Applied in Chemical Plant
Carrying idler rollers are light weight, dustproof, corrosion
resistant and self-lubricating and widely used on belt conveyors
for various industries. They greatly outperform other rollers when
applied in the factories of chemical, cement, sintering, power and
coal mines, where dust is heavy and corrosively is high.
We can manufacture the rollers of diameter 89-219mm length
190-3400mm, which are used in the steel industry, harbor, coal
industry, power industry, cement industry, etc. and we have Passed
CE certification and ISO9001: 2000 certificate. We also can make
any sizes according to your request.
Troughing Carrying Idlers are used for conveying bulk materials.
Usually three rollers in one group are installed on one set. They
are designed and manufactured with troughing angles of 20°,35°,45°.
Diameter:φ89-φ159mm; Tube width: 190-1800 mm.
|Specification of Belt Conveyor|
(Equal Troughing Idler)(mm)
|We also make customized impact rollers and other sizes plastic
rollers as your requests.|
● Outside diameter run out of roller: 0.5-0.7 mm
● Revolving resistance of roller: 3.3-3.5 N
● The axial movement distance of the roller between the frame is
less than 3 mm
● Applied in temperature: ≤ 80℃
Unique Design for Hongda Roller
► Dust-proof: "Integral labyrinth seal"design
a: Without other gaskets,the gap is small enough to keep dust
b: Double sealed dust-proof bearing,and before assemble the bearing
we add Lithium grease lubricant to protect it.
► Waterproof: Dust covers on both sides are out off the tube, so they can make
the water outside.
Corrosion-resistant: Outside materials of roller are plastics,the
characteristics of plastics make rollers resistant to
acid,alkaline,and organic solvent.
► No adhesion: Materials of roller pipe are Self-lubricating and low water
absorption ,so the rollers are difficult to stick concrete etc.
What Makes Hongda Rollers Top Quality
Unique design of roller body, two sealed covers in ends are out of
tube, which effectively prevents water in.
labyrinthine dust-proof design sets layers of defence, which
prevents the dust from entering the heart of roller -- bearing.
More components of the roller are treated by special technique,
less maintenance is needed during working processing.
After analysis of mechanical properties and physical properties of
various plastics, and after practice and test, Hongda finally
chooses NYLON, PP(Polypropylene), HMWPE (High Molecular Weight
Polyethylene) as the main material to produce the parts of roller
by modification or single way. The parts' work are aligned well in
variety of environments.
Craftsman's spirit, making every detail perfect from material
selection to processing.
Customize plastic(nylon) roller fitting in various adverse
circumstances according to customer's requirement.
