Installation & Maintenance
Installation Steps:
• Clean the shaft surface to remove burrs and grease.
• Press the bearing into the housing with a special tool to avoid impact.
• Adjust preload to ensure smooth operation.
Maintenance Tips:
• Replenish grease (lithium-based recommended) every 6 months.
• Install dust covers in high-dust environments.
• Regularly inspect shaft wear and replace promptly.
FAQ
Q: 1. What distinguishes 304 from 316 stainless steel bearings, and how to select them?
A: 304 stainless steel, which is the standard variety, exhibits fine corrosion resistance and economy, making it apt for common wet or slightly corrosive settings (such as food handling, medical devices). 316 stainless steel, (categorized as high-corrosion resistant, incorporates molybdenum for heightened chloride corrosion resistance, rendering it perfect for severe environments such as seawater, potent acids/bases, or chemical facilities (for instance, marine engineering, chemical apparatus). Kindly consult our engineers considering your particular corrosion requirements.
Q: 2. Stainless steel linear bearing What is the maximum operating temperature? Can it be used in low-temperature environments?
A: Standard models: Operating temperature range is -20℃ to 150℃. Customized models can withstand -40℃ or 200℃ (specify requirements in advance).
Notes for low temperatures: Use low-pour-point grease (e.g., lithium-based grease) to prevent lubrication failure; allow thermal expansion gaps during installation.
