THE BENEFIT OF TECHNOROLL IDLER
The shells are made from special ERW conveyor tube
with close tolerance ensuring smooth, eccentrically free
running with minimum diameter runout.
TechnoRoll rollers are fitted with single row deep
groove ball bearings, ZZ, RS sealed type with C3 or
C4 internal clearance and use long life grease. We
have selected these bearings because they give up
from eight to ten minutes angular deflection in
their operation, coupled with even load
distribution within each bearing race.
Made from carbon steel round bar. The round bar
are cut, turned with fine tolerance and ground
bearing seating to ensure press fit between
bearing and shaft
All the rollers are thoroughly tested for TIR,
rotation resistance, balancing, and water resistant
sealing before dispatch.
The bearing housing are made of deep drawn
quality sheet pressed to high degree of accuracy,
keeping tolerance at bearing seating region
as specified by the bearing manufactures.
Destructive vibration can arise from unbalance of
rollers producing fluctuating loads on the idler and
supporting structure. Excessive unbalance can
cause hammer on the bearings and loosening of
bearing and seal fits. TechnoRoll rollers to a range
of balance requirements from commercial quality
through to dynamically balanced for demanding
high speed – low noise applications. Every roll is
test run after final assembly.
Time tested and universally accepted multistage
sealing made from polymer and provide on both
sides of the bearings with dust-cover and
weather-seal. The components are assembled
together with high quality bearings.
Total Indicator Runout(T.I.R.)
Excessive T.I.R. causes noisy belt flap,
structural vibrations, roll unbalance and
reduced bearing life. TechnoRoll shells are checked
regularly during manufacture to ensure they
comply with quality standards established
by TechnoRoll. The high level of balance achieved
by TechnoRoll begins with the quality
of the electric resistance welded high speed
Jig welding of the base frames ensures slotted
mounting brackets are accurately aligned. This has
the effect for reducing installation costs and
belt wear. All roll supports are welded to provide
smooth weld surfaces for the application of
protective coatings. Welds are cleaned prior
to surface treatment.
Technoroll painting standard powder coating or
epoxy paint. Frames and structural members are
coated with epoxy paint or galvanized.
Our products have passed the quality control
procedures that are intended to ensure that
products manufactured do a set of defined criteria
for premium quality or meet the requirements of
the clients or customers.

We manufacture conveyor pulley for mining, cement, power plant, coal terminal and various applications in bulk material
handling. Our mission is to provide quality and competitive product to our customers. We can manufacture pulley to your
specification and design the pulley as your needs.
All pulley use locking device/element with RINGFEDER to connect shaft & hub. All pulleys are statically balance for non drive
and dynamically balance for drive pulley. The lagging for drive pulleys are provided by either cold or hot vulcanizing as per
customer requirement. Non drive pulleys are provided with plain lagging unless specified by customer. The shore hardness of
rubber lagging are 55 to 65 (durometer) Shore A.
PULLEY PRODUCT LINE
Drum Pulleys from 215mm to 2400mm diameter,
range from light to heavy duty pulley
We use only quality rubber lagging materials from Rema Tip Top
RfN 7012 RfN 7012 stainless RfN 7013 RfN 7014 RfN 7015
We use only quality rubber lagging materials from Rema Tip Top for cold lagging.
For hot lagging we use rubber made by ourself. Our rubber lagging product
for hot lagging called Soft Rubber G4-070-B.
Pulley Locking Assembly
CERAMIC LAGGING - Rema Tip Top CK-X
The “knobbly” surface of the ceramic tiles provides optimum grip on pulleys
subject to high stress. Ceramic material is suitable for pulley lagging,
due to its specific properties of extremely high wear-resistance provide by
aluminium oxide (A1203). It replaces traditional materials, because it provides
higher profitability by considerably increasing the service life and the efficiency
of pulley laggings. Ceramic lagging suitable for pulley lagging which subjected
medium to heavy load fabric or steel cord belt.
Ringfeder - Keyless locking assembly is a famous Locking device for quick mounting and dismounting. It has a benefit by
avoiding concentrating stress at the shaft due to any key way on the shaft from any regular device of locking element.
