Textile production lines, automated food packaging equipment and light conveying machinery mostly operate under intermittent swinging and low-speed reciprocating motion. Numerous bearing positions spread all over equipment make regular manual lubrication difficult. Traditional metal bushes require frequent grease replenishment. Leaking grease contaminates textile fabrics and food raw materials. Without timely lubrication, friction rises sharply, leading to dry friction, heat generation, abnormal noise and surface scoring, which shorten service life drastically. Conventional plain bushes perform poorly under boundary lubrication. Frequent start-stop motion accelerates abrasion and causes repeated production downtime.

Light automation workshops contain dust and fiber debris that mix with grease and form abrasive particles to speed up wear. Limited internal space in many machines prevents installation of external oil supply pipelines. Machinery manufacturers demand self-lubricating plain bearings that operate without continuous oil supply, feature compact dimensions, resist dust pollution and maintain stable wear resistance under low-speed swinging motion. Such bearings reduce maintenance workload and avoid material pollution caused by grease leakage to guarantee continuous operation of automatic production lines.

NMT Self-Lubricating Plain Bearings are integrally manufactured with multi-layer composite substrates. Solid lubricant embedded in surface layers gradually forms uniform lubricating films during operation to realize maintenance-free service. Outstanding boundary lubrication performance enables stable operation under low-speed rotation, reciprocating swing and intermittent start-stop conditions even when liquid lubricant is insufficient. Finely finished inner surfaces maintain low friction and limited temperature rise to prevent seizure and scoring. Thin and compact structure reduces installation space compared with rolling bearings and supports lightweight equipment design. Multiple material formulations are available for dry or slightly humid working environments.

A complete range of sizes and structures including cylindrical bushes, flanged bushes and thrust washers is supplied. Widely used in textile machinery, automatic food packaging lines, light conveying mechanisms, office automation equipment, small hydraulic guide components and stamping auxiliary modules. Standard overall dimensions enable direct replacement of traditional metal bushes without heavy redesign.
