T roller bearings he terrible events
Schaeffler’s T41D special spherical
Schaeffler’s latest T41D series of
special spherical roller bearings –
featuring X-Life quality standards and a
hard chromium Durotect CK premium
performance coating – are designed
to curtail fretting corrosion of shafts
and journal wear, setting new industry
benchmarks throughout Australia and
New Zealand for longer service life.
The quality engineering and durable
coating of Schaeffler’s T41D spherical
roller bearings results in a 70%
better lifespan when withstanding the
extreme stresses of the exciter units of
vibratory machinery.
The high durability bearings simultaneously
deliver greater load carrying
capacity, greater operational safety (by
preventing breakdowns and extensive
maintenance) and more efficient use of
space in heavy duty applications.
These bearings reduce maintenance
and downtime by optimising bearing
protection against loads encountered
in vibrating screens. Their high
durability also means operating loads
can be increased considerably over
the same lifetime as before, offering
compact and efficient use of space.
Schaeffler T41D bearings are purpose
designed to meet and exceed
the challenges of rolling bearings in
vibrating screens, which are typically
stressed by high, mostly shock-type
loads. Moreover, the bearings, while
rotating about their own axis, perform
a circular, elliptical or linear vibrating
motion. This results in high radial
accelerations which additionally stress
the bearings, and especially the cages,
considerably.

SET NEW INDUSTRY
BENCHMARK
in Christchurch in
March this year have
drawn attention to
the potential of lone wolf attacks
on innocent people by deranged
individuals.
Vehicles can be lethal in the
hands of attackers seeking
to cause maximum damage
to public and private facilities,
says Noel Maharaj, managing
director, HTS Group Ltd, which
is expanding its operations in
New Zealand to supply world
leading anti-terrorism solutions
to protect infrastructure and
materials handling facilities from
possible attacks.
“Enquiries for safety and security
technologies have trebled
worldwide in recent years, as
companies and organisations
are becoming more aware of
security risks evident globally,
and how to mitigate against
them,” says Mr Maharaj.
Ranging from simple barrier and
boom gates for carparks, right
through to advanced speed
gates with integrated controls,
HTS Group’s technologies are
designed to protect spaces from
unauthorised personnel that
may intend to cause harm. The
latest technologies include independently
tested crash-rated
bollards, gates and speed stiles,
designed to protect people from
threats inside buildings and out
in the open.
In addition to pedestrian safety,
the security and protection
of businesses and core
utility assets is a major focus
for security professionals.
Establishments are always a
good target for vehicle-borne
threats, which can come in
the form of vandalism or even
through aggressive attacks
from a determined terrorist or
criminal.
“Facility security should be
one of the primary issues that
businesses should have deeply
embed within their management
processes and systems. The
mobility of a vehicle means it
can be conveniently used as a
weapon for malicious individuals
and even as a delivery
mechanism for explosives,” says
Mr Maharaj.
“This is where Hostile Vehicle
Mitigation (HVM) comes in.
HVM’s primary goal is to
prevent hostile individuals from
breaching a perimeter successfully
or completing a criminal
act and accomplishing their
purpose. This type of system is
ideal for use in establishments,
crowded public spaces and
even in utility plants,” he says.
HTS Group specialises in
providing top quality HVM
equipment, including street
furniture, bollards, wedges,
barriers, fencing and vehicle
security gates.
