The "MD2300F/MD2310F" is a self-lubricating bearing that is resistant to seizure even when oil runs out in high-speed applications. Ceramics are uniformly dispersed in a porous sintered bronze alloy layer, which is impregnated with PTFE. By combining ceramics with excellent wear resistance and PTFE to enhance lubrication performance, it can be used in a wide range of applications. The structure of the base bronze sintered alloy layer has been modified, allowing for differentiation based on the conditions of use. 【Features】 ■ Stable performance even without lubrication ■ Resistant to seizure even when oil runs out in high-speed applications ■ Excellent wear resistance ■ Superior foreign object embedding resistance *For more details, please refer to the PDF document or feel free to contact us.

The "MD2500/MD2500F" is a wear-resistant, oil-free bearing. It is based on a lead bronze-based sintered alloy that is impregnated with a special resin. The impregnated resin disperses very fine PTFE particles ranging from 0.1 to 0.3 μm in phenolic resin. The effect of the PTFE microparticles achieves low friction. The "MD2500F" incorporates high melting point metals into the bronze, further enhancing performance and achieving lead-free status. 【Features】 ■ Low and stable friction coefficient ■ Excellent wear resistance ■ Superior initial compatibility under various conditions ■ Resistant to seizure during oil depletion ■ Uniform structure from surface to interior, ensuring no change in characteristics after inner diameter processing ■ Can withstand higher temperatures (200°C) compared to nylon and polyacetal-based resins *For more details, please refer to the PDF document or feel free to contact us.

The "MD3012" is a bearing that exhibits excellent performance in reciprocating motion, oscillating motion, and continuous operation. It features a two-layer structure with a copper-based sintered alloy layer that has a special solid lubricant uniformly dispersed on steel, designed for high temperatures and high loads. When used in conjunction with lubricating oil, it demonstrates even better bearing performance due to the good oil retention of the bronze-based sintered alloy layer and the action of the contained solid lubricant. The steel back metal uses steel plates to securely hold the alloy layer, enhancing the mechanical strength of the bearing and ensuring dimensional stability. 【Features】 ■ Usable under high loads ■ Exhibits excellent bearing performance in reciprocating motion, oscillating motion, and continuous operation ■ Excellent heat resistance ■ When used with lubricating oil, it demonstrates even better bearing performance due to the good oil retention of the bronze-based sintered alloy layer and the action of the contained solid lubricant ■ The bearing is thin-walled, allowing for compact design *For more details, please refer to the PDF document or feel free to contact us.

The "SBS10/SBS30" is a bearing that has fine ceramics uniformly dispersed and reinforced within a bronze sintered alloy layer. The amount of ceramics contained in each varies, and both have excellent characteristics in wear resistance and seizure resistance, allowing them to be selected based on the conditions of use. In addition to the solid type, there is a steel-backed type, both produced in sheet form. The ceramics are dispersed at an appropriate particle size that is compatible with steel to reduce the friction coefficient. 【Features】 ■ High PV value ■ Excellent wear resistance ■ Superior seizure resistance at high speeds *For more details, please refer to the PDF document or feel free to contact us.

"SBS40" is a bearing that excels in seizure resistance in high-speed applications. It combines fine ceramics and bismuth within a bronze sintered alloy layer. By uniformly dispersing bismuth, which has good affinity and can improve sliding properties, along with ceramics that excel in wear resistance and seizure resistance, it demonstrates excellent performance under various conditions. Additionally, by finely dispersing these materials, the strength of the bronze layer is maintained. 【Features】 ■ Exhibits high performance in areas prone to oil depletion or where grease is used ■ Shows a stable friction coefficient ■ Excellent seizure resistance in high-speed applications *For more details, please refer to the PDF document or feel free to contact us.

The "MF10" is a completely oil-free bearing that achieves both sliding performance and load-bearing capacity by layering fluorine fiber fabric and steel plates. The strength of fluorine monofilament is about 25 times greater than that of PTFE resin, allowing it to withstand very high surface pressures. It exhibits its characteristics when used under high load and low speed, and does not experience stick-slip even without lubrication. It features a hybrid structure where fluorine fiber fabric is firmly bonded to a backing (primarily made of soft steel SPCC) through an intermediate layer. 【Features】 ■ Can be used completely oil-free ■ Of course, it can also be used in areas with grease ■ Can withstand very high surface pressures ■ Can demonstrate its characteristics when used under high load and low speed ■ Does not experience stick-slip even when completely oil-free *For more details, please refer to the PDF document or feel free to contact us.
