A prospective customer got in contact seeking an alternative to the now discontinued Rocol® Kilopoise™ damping grease. The application was the opening mechanism of a photo scanner feed table; the customer being a company that specialises in the service and refurbishment of photo scanners. The feed table opening mechanism relies on a type of spring release, the two materials are metallic.

The use of an effective grease is a small but very important part of the photo scanner refurbishment process for the customer. Thank you to Stu Cully Photo Services for the video clips and images – www.stuculleyphotoservices.com

Challenges

The weight of the photo scanner feed table/cover is such that an extremely stiff grease is required otherwise there will not be a controlled fall.

Proposed Solution

  • A super sticky synthetic grease that exhibits extreme levels of damping to slow the drop movement of the photo scanner.
  • A grease based on a polybutene base oil and a silica thickener have the necessary damping characteristics.
  • Ideally then chosen damping grease should exhibit low levels of oil separation.

Product Selection

Tribosyn PG44A

Applying The Grease

PG44A is generally sold in jars as it’s so stiff that squeezing from a tube is not practical. The grease is applied from the jar and should cover the whole of the shaft, before the mechanism is reassembled.

Results

The Tribosyn PG44A was a great success and gave the desired level of damping to the feed table. The feed table release/drop motion became a controlled action and helped improve the perceived value of the refurbished device.

Tribosyn PG44A was a perfect replacement for the Rocol® Kilopoise™ damping grease

Small jars of PG44A can be purchased at our online shop.
