When food, beverage and primary processing operations are in full swing, the last thing any operations manager wants is extended stoppages caused by bearing failures.
Avoidance of such issues is particularly important when seasonal factors are involved, or when products have to be processed, cut, shaped, manufactured and packaged to tight export deadlines.
Where bearing failures or incipient problems are encountered, split plummer blocks from Cut To Size Plastics can be particularly valuable for maintenance tasks where production and process staff want to minimise disruptions to production caused by bearing replacement.
Light, easily handled and self-lubricating split blocks can be machined from polyurethane and other engineering grade plastics for diverse materials handling applications, often involving machinery with multiple bearings and shafts inline where it would be costly to close down the entire line for removal and installation of heavier and more complex bearings.
Where the split blocks are used in particularly corrosive or aggressive environments – ranging from food and beverage through to primary production and handing of chemicals involved in manufacturing – the blocks can be engineered from other high-performance plastics particularly suited to the particular task, says Pat Flood, NSW Manager of Cut To Size Plastics, which has been supplying Engineering Plastics to Australian and international customers for over 35 years Flood.
"Split plummer blocks manufactured from engineering plastics have a number of natural advantages over metal alternatives. In addition to hygienic surfaces that are easy to wash down, there are often significant cost advantages in fabrication and speed of replacement.
"Often engineering grade polyurethane bearings, with a shore hardness of 75D, can be used to provide an excellent interim solution that saves time and money, while in other situations they provide a highly cost-effective long-life solution.
Polyurethane split plummer blocks – which are designed for quick removal and installation – provide advantages that traditional bearings do not, including:
- Light weight for speed and OHS benefits
- Self-lubricating for production security and time savings
- Wear improvements
- Tear and weather resistance
- Heat and cold resistance
- Lower operating costs
- Long life
- Noise abatement
- Capable of working in extreme wash-down applications
- More sanitary
Polyurethane has been widely proven in robust materials applications - including in the timber industry, for example – offering industrial applications the elasticity of rubber combined with the toughness and durability of metal, to reduce plant maintenance and OEM product cost, says Flood.
In addition to split roller blocks, Cut To size Plastics engineers a wide diversity of machinery components and Hercules brand load and slip bearings used extensively by industries ranging from production and process engineering, manufacturing and materials engineering, timber, paper and primary product processing, food and beverage, agricultural product processing and water and waste water plants.
