Excavator feed guide wheel bearings

Excavator feed guide wheel bearing A guide bearing is a roller, plate, or block that reduces wear, maintains alignment, and minimizes friction on moving parts. Guide bearings are commonly found on saws, machining tools, and other equipment that requires alignment of moving parts. Smaller bearings may use low-resistance polymers or plastics, and larger loads may require the use of metal rollers and lubricants.Damage to excavator guide wheel bearings can lead to loose chain. One of the causes of derailment is the damage of bearing of belt pulley, bearing of supporting wheel, chain protector and excessive wear of driving teeth. Stones and other foreign bodies in the work into the chain rail is also one of the reasons for derailment. Usually, try not to walk backwards when driving, and the chance of losing the chain when walking backwards is relatively large. Walking backwards is that the driving wheel is in front, and the normal time needs to guide the wheel in front, which also needs to…
