Grease Fitting
Provides the access port for injecting lubricant into a reducer or bearing housing during maintenance.
Grease fittings provide the access point for injecting fresh grease into a reducer or bearing housing during scheduled maintenance, without needing to disassemble the joint.
Correct grease type and injection volume matter as much as the fitting itself, since over-greasing a sealed joint can build internal pressure and damage a seal, while under-greasing accelerates gear and bearing wear.
A clogged or damaged fitting is a simple problem with an outsized consequence, since it can lead a technician to believe a joint has been serviced when the grease never actually reached the internal components.
Common questions
- What does the Grease Fitting do?
- Provides the access port for injecting lubricant into a reducer or bearing housing during maintenance.
- How does the Grease Fitting fail?
- Common failure modes: Clogged fitting preventing grease from reaching the joint, Damaged check valve allowing grease to leak back out, Over-greasing damaging an adjacent seal from excess pressure, Physical damage to the fitting from tooling or collision.
