High Quality Oil-free bearing slide rail

Oil-free bearing slides are self-lubricating sliding components utilising high-strength brass and graphite. Their core structure comprises a composite of ‘metal matrix + solid lubricant’, enabling long-term stable operation without additional lubrication. They are particularly suited for harsh or inaccessible maintenance conditions, finding application in mould manufacturing and linear guides for automated equipment.

product details

Product Features

Self-lubricating and maintenance-free: There is no need for extra oiling because graphite naturally seeps out during friction to produce a lubricating layer. A broad operating temperature range of -40°C to +300°C is suitable.

Extreme environment resistance: The brass matrix provides impact toughness and corrosion resistance, withstanding dynamic stresses of up to 100N/mm². Perfect for challenging circumstances including exposure to seawater and dusty surroundings.

Product Advantages
