Below-ground material handling equipment must withstand heavy loads and large amounts of dust, mud and grime. The full line of Timken housed units can quickly conquer these challenges.
With the full line of Timken spherical roller bearing solid-block and split-block housed units, Type E tapered roller bearing housed units and the complete problem-solver series of Timken ball bearing housed units, high performance and optimal uptime can become standard operations.
When New Clydesdale Colliery in Mpumalanga, South Africa, an EXXARO location, experienced premature bearing damage on the tail pulleys of its conveyor system, operators challenged their bearing distributor to find a solution. The distributor asked Timken to help meet the challenge in an application where the competitor’s bearing was failing.
“We were getting eight weeks maximum bearing life with our previous solution. From fractured housings to seal failure and higher- than-normal maintenance cycles, the issues ran the gamut,” said Frans Botha, mechanical foreman at New Clydesdale.
“Timken presented the SRB solid-block housed unit as a potential solution and we gave it a try. We experienced benefits right from the start. It took us approximately 30 minutes to install each unit, compared to an hour and a half normally required to reinstall the previous split-block units. Now, 10 months later, the original units are still running and our maintenance cycles have been reduced significantly.”
