J-LIN-11R-16 RJUM-11-16 Plastic Linear Bearings

J-LIN-11R-16 plastic linear bearings feature an aluminum alloy body reinforced with fibers, offering maintenance-free operation, low noise, and dust resistance. In contrast, RJUM-11-16 plastic linear bearings are constructed from iglidur®J material in a sealed, elongated design. These bearings exhibit minimal clearance, exceptional wear resistance, and require no lubrication, effectively mitigating the effects of grit and contaminants.

brief introduction:

Plastic linear bearing is a self-lubricating linear motion system, the biggest difference between metal linear bearings is that metal linear bearings are rolling friction, the point contact between bearings and cylindrical shafts, so this low load high-speed movement; The plastic linear bearing is sliding friction, and the bearing and cylindrical shaft are in surface contact, so this is suitable for high load and low speed movement.

Plastic linear bearing bearing mating shaft has no special requirements; It can withstand greater loads than metal bearings, but because the movement between the bearing and the shaft is sliding friction, the motion speed of plastic linear bearings is limited to a certain extent; The motion resistance is larger than that of metal linear bearings; However, its motion noise is lower than that of metal linear bearings, especially in the case of medium and high speed, the impact of plastic linear bearings noise with speed is very small. Plastic linear bearing because of its internal chip groove design, so allowed to be used in large dust occasions, dust in the process of movement automatically from the chip groove out of the bearing body friction surface; Plastic linear bearings also allow cleaning during use, and the internal sliding film made of special materials can even be used for long-term operation in liquids.
