Q: What grease type should be used with this fitting?
A: Use NLGI Grade 2 multipurpose lithium complex grease or equivalent. Do not use grease containing graphite or MoS2 unless specified by the forklift manufacturer. Grease consistency and type affect load wheel and pivot performance.
Q: How often should this grease fitting be serviced?
A: Forklift grease fittings should be lubricated every 250 to 500 hours of operation or quarterly, whichever comes first. Increase frequency in wet or dusty environments. Overgreasing can cause load wheel failure; undergreasing causes bearing wear and steering issues.
Q: Is this a standard metric or NPT fitting?
A: This is a metric M8x1.25 fitting, not NPT. Confirm your equipment uses metric grease fittings before ordering. Do not attempt to install NPT adapters as this can result in grease leakage and bearing damage.
