Textile machinery, automatic packaging production lines, material conveying equipment and light construction machinery contain numerous transmission positions with low-speed rotation, reciprocating oscillation and intermittent operation. Conventional rolling bearings require regular grease replenishment and bring heavy maintenance workload. In dusty working environments, grease easily absorbs impurities and forms abrasive particles, accelerating bearing wear and shortening service life. Many compact mechanisms have no reserved space for oil circuits, making continuous lubrication impossible. Ordinary oil-impregnated bushes lose lubricant after long-term operation, resulting in dry friction, abnormal noise and jamming failures.

Some textile and packaging production environments impose strict control over oil pollution. Leaking grease may contaminate raw materials and finished goods and damage product quality. Certain tooling mechanisms start and stop frequently and bear alternating loads. Ordinary sliding bushes lack sufficient wear resistance. Clearance gradually expands after long-term operation and leads to equipment vibration and positioning accuracy loss. The market demands self-lubricating plain bearings with excellent wear resistance for oscillating and low-speed rotary operation to cut maintenance frequency and avoid oil contamination risks.

NMT Self-lubricating Plain Bearings adopt composite structure of metal base and solid lubricant. The metal base ensures mechanical strength and load capacity, while embedded solid lubricant is continuously separated during operation to form stable lubricating film on friction surfaces, realizing long-term oilless maintenance-free operation. The bearings adapt to continuous rotation, reciprocating oscillation and intermittent start-stop motion, withstand alternating radial loads and fit mixed low and medium speed working conditions. Standardized inner and outer diameter dimensions and compact wall thickness support compact mechanical design for limited assembly space.

Multiple base materials and lubricant formulas are optional for dusty environments, medium-load conditions and clean production scenarios. End face and outer circle structure can be customized to meet assembly demands such as flange limiting and axial positioning. Stable friction coefficient lowers temperature rise and reduces wear debris. No complicated oil supply system is required, eliminating oil pipelines and fittings and simplifying overall structure. The bearings are widely used in automation equipment where frequent refueling and oil leakage are prohibited.
