Case Studies
Chesterton® 615 HTG #2 Grease Helps Lower Bearing Failure Rate and Increase Bearing Life
Challenge
Background
A concrete production plant has 12 bearings in each autoclave transport rig and a total of 67 autoclaves. Their previously used grease charred when exposed to temperatures between 250°F– 350°F. As a result, there were about 50 bearing failures per month. The facility wanted a grease that will perform well at high temperatures of up to 350°F and reduce the bearing failure rate.
Failed bearings on autoclave transport rigs.
Solution
Product
Chesterton specialists recommended Chesterton 615 HTG #2 High-Temperature Grease after analyzing the problem. The plant’s procurement department was concerned about the cost differences in switching, but later they agreed to run a trial due to the severe nature of the bearings failure. 615 HTG #2 High-Temperature Grease is capable of operating at its highest strength even at higher temperatures and can reduce varnish and gum formation.
Chesterton 615 HTG #2 High Temperature Grease performs well up to 400°F.
Results
Bearing Life Increased
After switching to 615 HTG #2 High Temperature Grease, the bearing failure rate dropped from 50 per month to 3 – 8 per month, with most bearings lasting over 6 months.
- Estimated replacement cost of $120 per bearing.
- Previous Bearing replacement cost per year = $120 x 600 bearings = approx. $72,000.
- Current Bearing replacement cost per year =$120 x 100 bearings = approx. $12,000.
- Reduction of annual bearing replacement costs = approx. $60,000.
$70,000 to $80,000 anually ($=USD). Their maintenance staff is highly satisfied with the results.
