It’s not uncommon for machinery in building material manufacturing to be exposed to large amounts of dust or water splashing. Be it in cement production plants, brick kilns or steel mills, heavy air-borne dust and high humidity can greatly impact the bearings’ performance. That is where...

Ever since Dr. Georg Schaeffler first invented caged needle roller bearings over 70 years ago, the bearings have found extensive applications in a range of industries. While commonly used for power transmission in the automotive industry, needle roller bearings are also used extensively in the building...

The recent coronavirus pandemic has once again brought to light the need for a resilient waste management sector that can facilitate the move towards a circular economy. The Australian Council of Recycling estimates that Australian households have thrown out as much as 10 per cent more...

Processes in building material manufacturing often involve high temperatures and critical stresses. Cement, tile and brick production processes require hammer mills to crush the aggregate material into smaller pieces and then vibrating screens to classify these crushed particles by size.

Rotating Bearings tend to be the ‘star’ components of production machinery, with the importance of their role discussed often. However, industry expert John Tawadros points out that linear bearing guidance systems are just as essential, particularly in production environments where high dynamic loads and contamination can impact production efficiency.

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 facilities1. This is why it’s essential to keep the rotating equipment at Recycling Plants in good service, says industrial bearing expert, Tony Tormey.

“Once we put them in, we don’t have to worry,” says Omar Kheir about the Timken® spherical roller bearing solid-block housed units. As State Engineering Manager for Sims Metal Management in New South Wales, that’s high praise. Sims Metal Management is the world’s leading – and publicly listed – metal recycler, with wide-ranging operations in Australia. The company was founded in Sydney back in 1917 and has grown to include over 250 recycling facilities in more than 20 countries worldwide. Sims Metal Management specialise in the buying, processing and reselling of ferrous and non-ferrous recycled metals.

When the bore diameter of a bearing is 1.5 metres, it’s not classified as an ‘off-the-shelf’ item. Yet these extra-large bearings are often employed on critical pieces of equipment, such as the trunnions of grinding mills at mine sites. This is why a trusted supplier with engineering expertise in the installation and maintenance of these bearings is so important to the customers that use them.

The marketing motto adopted by Japanese-founded bearing manufacturer NTN, with its history of more than 100 years, is to ‘make the world ‘NAMERAKA’, with ‘NAMERAKA’ meaning ‘SMOOTH’ in Japanese. It’s an apt tagline as NTN is renowned for its production of anti-friction bearings, which are made to be smoother than the surface of a mirror.
