When 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 and local delivery 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 spilt blocks can be produced 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 Bill Novak, National Sales Manager, Cut To Size Plastics, which has been supplying Engineering Plastics to Australasian and international customers for over 35 years. Cut To Size Supplies a wide range of products to the timber industry, including Chanex® chain guides and profiles, idler and drive sockets, J hooks, wear strips, chain channels, roller lugs and conveyor springs. These products are manufactured from light, tough engineering plastics such as low-friction polyurethane and UHMWPE formulations.

“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 Mr Novak.
