Hi,
looking at an application that has been problematic.
High load (150 tonnes), and slow speed (4RPM) application with thrust bearing and two guides (plain, leaded bronze), in an application that can see temperatures in the 100-150 range (higher if things play up.
Grease lines are about 50-60' long, and 10mmNB. Grease must by nature have a high level of solids (MoS2), and has traditionally been a Lithium soap. Grease is pumped metered quantities on a timer, a number of times per hour.
Grease lines block with hardened grease occasionally, which is bad mojo.
The group have been offered a polyurea based grease as an alternative. Still high MoS2 content.
Any thoughts on whether this is a better alternative ?
