Long-term maintenance free
A lubricator used in the ball screw and a contact scraper provides
long-life and maintenance-free operation. maintenance free operation.
Needs no maintenance for long periods
Grease lubrication on the ball screw is usually lost a little bit at a time
with ball screw
movement. The SR type has a lubricator that supplies grease lost over long periods to ensure
near maintenance-free operation Note.
Note. The maintenance-free period is within the running life of the robot.
Grease-saving lubrication system
The lubricator uses a high-density fiber net that supplies just the right
amount of grease in an
eco-friendly lubrication system that wastes no grease.
Prevents contaminant particles
The dual-layer scraper in contact with the rod removes micro contaminant
near-perfect performance. It scrapes away tiny par ticles adhering to the rod in a multi-step
operation that prevent trouble from contaminants that might otherwise penetrate to internal
parts. Synthetic foam rubber with a self lubricating function ensures low-friction
Grease gun nozzle tube (YAMAHA recommended nozzle tube)
This nozzle tube is even usable when there is little space around the grease port. For example,
when the SR04 or SR05 space-saving model is used with the motor facing up, the grease port is
positioned on the side of the robot body. This may make it difficult to refill grease depending
on the positions of other robots or peripheral units.
Model : KCU-M3861-00
Note. This nozzle tube can be attached to a commercially available ordinary grease gun.
