11. FAQs
What are the advantages of using linear bearings over traditional sliding bearings?
Linear bearings offer smoother motion, higher precision, reduced wear, and longer lifespan.
How do I calculate the load capacity of a linear bearing?
Load capacity is typically provided by the manufacturer based on bearing size and material.
What is the difference between a linear ball bearing and a linear roller bearing?
Ball bearings use recirculating balls for low friction, while roller bearings utilize cylindrical rollers for increased load capacity.
How often should I lubricate linear bearings?
Lubrication frequency depends on application, environment, and bearing type. Consult the manufacturer's guidelines.
What are some of the common causes of linear bearing failure?
Improper selection, overloading, contamination, misalignment, and lack of lubrication can all contribute to bearing failure.
Can I use linear bearings in harsh environments?
Yes, some linear bearings are designed to withstand extreme temperatures, dust, moisture, and corrosive agents.
