                                    Sliding bearing
                                    Plain bearings are bearings that work under sliding friction.
                                    Sliding bearing works stably, reliably and noiselessly.
                                    Under the condition of liquid lubrication, the sliding surface can be separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has certain vibration absorption ability.

                                    Type (PTFE coated sliding bushing) Steel + porous bronze sinter + PTFE


                                    Lead-free flange bushings have PTFE sliding surfaces and tin-plated steel bodies, making them an effective substitute for places that cannot or must not be lubricated. Select this type for low speed, high load applications, or low speed and high load applications. This sleeve is suitable for applications where friction and heat should be avoided. The sleeve can also be used, for example, in oil or water, and has good corrosion resistance. In addition, the model can withstand very high and very low temperatures and has a low coefficient of friction. For example, in fitness equipment.
