BMG’s inhouse BTC bearing block unit (BBU) and housing products are manufactured exclusively for BMG, to stringent quality and safety specifications.
BMG robust inhouse BTC bearing block unit (BBU) and housing products, which are manufactured exclusively for BMG to stringent quality and safety specifications, have been developed for use in tough conditions.
“Although the BTC range was originally designed for light to medium rotating equipment applications – like packhouses and small conveyors in general industry and the agricultural sector – recent important upgrades enable BTC bearings and components to be used safely in many demanding industries,” explains Carlo Beukes, Business Unit Manager of BMG’s Power Transmission division. “Typical medium to heavy-duty applications include underground and overland incline conveyor systems, as well as crushers.
“The first phase of the BTC bearings project involved an upgrade of all aspects of the bearing block units (UCP pillow blocks, UCFL and UCF flange, UCT take-up) designs, while the second phase encompassed advancements of the bearing housings (light duty SN and heavy-duty SD series).”
Phase one upgrades included an improved quality housing to ensure a stronger component that does not crack in tough conditions and a higher grade of steel for greater load capacity and speed stability.
Upgraded BBU’s benefit from an efficient amount of high-performance grease (between 30% and 40% fill). For user convenience, these bearing blocks are supplied with an Allen Key and the installation and maintenance schedule is printed in English and Zulu, which is another first for this market.
Phase two of the project involved the upgrade of all aspects of BTC bearing housings. Materials have been advanced from SD3134 to SD3164, in line with international premium brands. Grey Cast Iron HT200 grey, which replaces grey Cast Iron HT 150, can accommodate up to 200 Megapascal pressure ratings.
In addition, SD3168 and larger sizes, are now manufactured from grey Cast Iron HT250 which can accommodate up to 250 Mega pascal pressure ratings.
Special attention was given to improving the dimensional control on the housing bore tolerance, to ensure an optimal fit between the bearing and housing and to the sleeve tolerances, to prevent any run-outs. Other advancements include improved sealing arrangements to prevent the ingress of contaminants into the bearing housing, thereby safeguarding the unit, as well as the upgrade of all bearing locking elements.
BMG specialists emphasise that these design improvements and quality enhancements require selection of the correct lubrication solutions. A top-quality lubricant will ensure that the equipment is able to reach its L-10 design lifetime.
A wide range of industrial quality branded lubricants is available from BMG, including the extensive HABOT grease range. BMG experts – with a thorough understanding of equipment lubrication requirements and the properties of different greases – assist customers with selection of the correct lubricant for preventative maintenance to ensure optimal performance of machinery and equipment.
By considering factors, such as operating temperature, load capacity and environmental conditions, the correct product is chosen for smooth operation, extended service life of equipment and reduced downtime.
BTC bearing block units are available from BMG’s extensive branch network, as well as through the company’s online shopping platform. This online shopping portal adds value to BMG’s service offering and makes shopping for engineering components even more convenient.
BTC bearings and components for tough conditions
Originally the BTC range was developed for light to medium rotating equipment applications, including packhouses and small conveyors in general industry and the agricultural sector. However, with these recent important upgrades, robust BTC bearings and components are perfectly suited for heavy-duty applications in mining, for example crushers and overland incline conveyor systems
