While Australia’s recycling sector has grown considerably since the 1990s, there is increased pressure on operators to recycle waste more efficiently – particularly in the wake of the China National Sword import restriction and a media focus on Australia’s waste management facilities.
This is why it’s essential to keep the rotating equipment at Recycling Plants in good service, says industrial bearing expert, Tony Tormey.
“The NTN Ultage spherical roller bearings are a popular choice among clients in the recycling sector because they offer superior longevity – up to five times longer service life than other spherical roller bearings,” explains Tormey, who is CBC Australia’s Product Manager for Industrial Bearings.
“Nearly all of our customers in the recycling industry are using Ultage bearings in at least one application at their plant.”
Unlike its traditional spherical roller bearing predecessors, the NTN Ultage series comprises a completely new design. The main feature of this design is the increased roller diameter which makes the Ultage bearings suitable to all applications with high radial loads.
“The Ultage is the ultimate spherical roller bearing that NTN produce. This series provides an industry-leading performance with dynamic load ratings of up to 65 per cent more than NTN conventional spherical roller bearings, in addition to an increased service life of up to five times more than our traditional spherical roller bearings and at least one and a half times increased fatigue strength,” says NTN-CBC Product Manager for Bearings, Fabio Rebecchi.
“With environmental demands being more prevalent and the recycling sector growing so rapidly, we’re seeing a significant increase in demand for these spherical roller bearings.”
Spherical roller bearings are used in all recycling material recovery facilities. Typical applications include conveyor rolling systems, vibrating screens, sorting machines, shredding machines, grinding machines, crushing machines and in all pulp and paper mill machinery.
Rebecchi points out that the Ultage series has a custom bearing type to suit each and every one of these applications.
“There are six types of Ultage bearing types that we stock for use in various Recycling Plant applications. In fact, the name ‘Ultage’ is a combination of the words ‘ultimate’ and ‘stage’, which indicates NTN’s intention in designing an industry-leading performance spherical roller bearing that can be employed in a diverse range of applications”, explains Rebecchi.
“The Ultage series bearings have the world’s highest standard load capacity. This has been achieved by maximising the roller diameter as well as the number of rollers and roller design.”
Another key benefit of the Ultage series range is that they will function at optimal capacity in temperatures of up to 200 degrees Celsius. Ultimately, these features provide significant cost savings from a total cost of ownership perspective.
“The service life that operators are getting from the NTN Ultage series is just first-class. Not only do operators within the recycling sector get increased productivity from their equipment, these high-performing Ultage bearings also reduces the amount of maintenance needed on machinery,” says Tormey.
Customers within the recycling segment also stand to gain from the unique joint venture between CBC and NTN. Particularly as one of the NTN-CBC company directors, Mr Jerry (Takao) Maki, is based locally.
Maki has held various posts within NTN and has been working with the Japanese manufacturer since 1981. His ability to tap into the NTN global network and directly communicate with the company’s manufacturing and design divisions makes him a great asset to NTN-CBC Australia.
“In the recycling sector, the focus is always on uptime of machinery and NTN being able to provide superior products for applications in this segment,” explains Maki.
“The Ultage series bearings are highly-engineered products. We have total access to the manufacturing division and can ensure our customers in Australia are paired with the correct Ultage type for their application.”
Tormey reiterated the fact that having access to the manufacturer is a major advantage, but also noted the importance of CBC’s availability and accessibility to customers.
“At CBC we take pride in our understanding of a customer’s requirements and their plant requirements. As well as having the right parts and on-time delivery, we provide full engineering services to help improve the uptime of rotating equipment.”
