SKF Transmission Chain Catalogue - Waikato Bearings

Rollers
SKF Chains use solid rollers that are cold extruded from bar stock, resulting in good fatigue strength and improved shock loading
capabilities. All rollers go through a hardening process to ensure an extended wear life. To avoid crack propagation, shot peening is
introduced, this also gives the rollers better fatigue strength which provides the required protection.
Parts manufacturing lines
Microhardness testing equipment where batch tests
are done to ensure hardness is within specification
Assembly process
Advanced automation machines ensure that the parts are assembled to the correct tolerances giving SKF Chains a precise spaced
pitch with a perfect fit. Every part and process is subject to strict quality controls with frequent checks to ensure conformance to
tolerances and standards. Depending on the requirements, various anti-corrosion treatments and special coatings are readily
available upon request.
The assembled chains are then pre-stretched. This running in of the chain not only eliminates initial elongation but also increases
the chain’s fatigue resistance.
The final process of pre-lubrication provides SKF Chains with lubrication that is ready for the chains initial start-up. The pre-lubrication
also acts as a corrosion protection for an assured long shelf life.
