Design the lubrication system to ensure adequate lubrication flow to the sleave bearing.
FAQs About Sleave Bearings**
Q: What is the difference between a sleave bearing and a roller bearing?
A: Sleave bearings have a sliding contact between the shaft and the bearing, while roller bearings use rolling elements to reduce friction.
Q: How do I troubleshoot sleave bearing problems?
A: Common problems include excessive noise, vibration, and overheating. Check lubricant levels, bearing clearance, and shaft alignment.
Q: What is the typical service life of a sleave bearing?
A: The service life depends on the operating conditions and lubrication. With proper maintenance, sleave bearings can operate for thousands of hours.
