Introducing our low friction coefficient copper sleeve maintenance bushings specifically designed for injection molding machines. These bushings are crafted from high-quality copper materials, renowned for their excellent conductivity, corrosion resistance, and durability.
The key feature of these bushings is their low friction coefficient, which significantly reduces the amount of friction generated during the injection molding process. This reduction in friction not only improves the efficiency of the machine but also extends the lifespan of the bushings and other related components.
Moreover, our copper sleeve bushings are designed for easy maintenance and replacement. This ensures minimal downtime and quick turnaround in case of any wear or damage. The bushings' precision-fitted design also ensures a snug and secure fit, minimizing any potential for leakage or misalignment.
Wh you're looking to upgrade your existing injection molding machine or are in the market for new bushings, our low friction coefficient copper sleeve maintenance bushings are an excellent choice. They offer superior performance, durability, and ease of maintenance, ensuring smooth and efficient operation of your injection molding machine.

When high load applications encounter bad working conditions, maintenance becomes a big problem, how to extend the service life of parts, at the same time, reduce the cost of later maintenance?
VIIPLUS BRONZE bearings have opened up a new way of thinking about solving this problem.
Sleeve bronze sleeves due to its low manufacturing cost, better wearing quality and longer service life.
Oil Grooves Type For Cast Bronze Bushings
Double Loop and Double Figure Eight recommended for grease only.
Made-To-Order Cast Bronze Sleeve Bearings
Oil & Grease Groove Bronze Bushings & Flanged
Groove Type :Single Loop Figure Eight Straight & Circular Double Loop Double Figure Eight Half Figure Eight Straight Circular
Note: In order to form a more perfect oil film between the bearing & shaft, we recommend a V-shaped groove whenever the design permits, as it allows full flow of the lubricant across the bearing surface.
