FAQ
Reader questions
What operating temperatures are supported by standard INA bearings?
Standard INA bearings typically handle operating temperatures from around -30 to +120 degrees Celsius, depending on the cage and seal materials. High-temperature or specialized low-temperature variants are available for extreme conditions.
How do I interpret the dynamic load rating (C) for an INA bearing?
The dynamic load rating indicates the constant radial load a bearing can theoretically endure for a basic rating life of one million revolutions. Use this value to compare options and size bearings for your expected loads.
Can INA bearings be used in washdown or food processing environments?
Yes, many INA bearings feature stainless steel materials, enhanced seals, and special lubricants that meet food-grade and washdown requirements. Verify the exact product documentation to ensure compliance with regulatory standards.
What maintenance practices maximize the service life of INA linear guides?
For INA linear guides, regular cleaning, proper re-lubrication, and ensuring correct alignment reduce wear. Sealed units minimize contamination, while scheduled inspections help detect wear early and prevent performance loss.
