Avoids Field Failures and Protects Threads from Corrosion

LTM India is tyre processing machines manufacturer used nylock nuts to lock the heavy M16 bolts on the pci machines. However, the nylock nuts loosened due to heavy vibrations and thermal cycling that the tyre machines are subjected to. Loctite 243 medium strength threadlocker was recommended for this application. Loctite 243 does what nylock nuts can’t - they filll the gap between threads and locks the threads together - creating a unitized assembly that does not loosen under severe vibrations and thermal cycling.

Eliminates Need for Expensive Machining

The drive bearing of a new model of portable cleaning machines needed to be mounted in the cast iron gear housing. As the Gear housing is cast, it is very difficult to maintain the tolerances. Machining the bearing seat area involved high machining cost and time. Henkel’s Loctite products were recommended for this application: Loctite 660 Quick Metal Retaining compound was used along with 7649 Primer to retain bearing to housing and Loctite 242 used to lock the screws of gear to housing which creates 100% metal-to-metal contact between the mating parts increasing the load carrying capability as well as preventing the area from fretting corrosion.

Loctite® Manufacturing Reliability Gives Maintenance Team The Know-How.

An upper Midwestern paper mill operates several multifuel boilers for power and steam generation; the primary fuel being coal. Natural gas is also used to fuel the boilers when the coal supply is exhausted or interrupted. The switch-over process from coal to natural gas is expensive due not only to the cost of the fuel, but also since it requires the shutdown of parts of the paper manufacturing operation.

Design Solutions from Loctite® on Arctco’s Tigershark Personal Watercraft

Arctco Sales, Inc. has been building Arctic Cat snowmobiles for years. So when they decided to launch a line of personal watercraft, they assembled all of their problem-solving suppliers from the beginning. Loctite® had a long track record in providing solutions for their snowmobile line. “We think of Loctite® as an extension of our engineering team, providing value-added technology and cost-effective design solutions throughout our assembly. We literally put Loctite® on our design team in the product development phase.” Ron Ray, Vice President of Manufacturing said.

Prevent Misalignment Problems and Equipment Failures.

Hydropulpers are machines designed to agitate a mixture of paper pulp and water to prevent dewatering until this mix can be used in the papermaking process. These particular hydropulpers are driven by 150 hp motors coupled to right angle gearboxes. Coupled to the output shafts of the gearbox is a large blade which is in the bottom of the hydropulper vat. Due to extreme vibration incurred by the hydropulper, our customer was having problems keeping the mounting bolts for the gearbox tight.
