Spherical plain bearings found in a compactor’s articulating joints are preforming in harsh environments and under demanding conditions. To maximize the life of these bearings, original equipment manufacturers should work with bearing experts in the design phase of development.

Important elements to discuss with a bearing manufacturer include:

Where is your PTFE woven?
Spherical plain bearings, rod ends and bushings with PTFE do not require maintenance. Some bearing manufacturers like CCTY Bearing weave PTFE on-site, which allows for a formulation that is specific to the application. The main benefit of an individualized PTFE formulation is a longer life for the bearing as it is designed to withstand specific working conditions.

What heat treatment process do you use?
Highly controlled heat treatment ensures that the final product is hardened to a specified level – significantly improving wear resistance and reducing exposure to potential bearing failures.

It is also imperative to know if the manufacturer has their own heat treatment on-site or if it is subcontracted. Precision manufacturers like CCTY Bearing maintain all critical processes – including heat treatment – in-house for heightened control on the final product.

Where are the bearings tested?
Technical validation, comparison assessments and quality control are the main reasons for testing bearings. For technical validation, tightly controlled parameters give manufactures the ability to verify the life of a bearing, impact testing and environmental performance.

In order to conduct these tests, a manufacturer needs access to test rigs that simulate compactor articulation joints. On-site test stands, as opposed to third-party test stands, allow the manufacturer to continuously monitor the cycles and results.

Testing through a third party can greatly add to costs. Reputable bearing manufacturers with on-site rigs like CCTY do not use testing as a profit center.

What other construction equipment uses your bearings?
The construction field is tough on equipment and its internal components. Choosing a bearing manufacturer that has proven itself in other applications within the Indian construction market provides peace of mind.

Look for a manufacturer who works with your design team to formulate the right solution. A consultative approach should focus on finding ways to provide a reliable bearing solution with low friction and a long service life.
