Instruksi Manual

1. Bubuka

This manual provides essential information for the proper installation, operation, and maintenance of your Nice ER12 Double Sealed Ball Bearing. Adhering to these guidelines will ensure optimal performance, extend the lifespan of the bearing, and maintain safety.

The Nice ER12 is a single-row radial ball bearing designed for applications requiring support for medium radial loads and operating speeds up to 5000 RPM. It features an extended inner ring with set screws for improved shaft support and synthetic rubber seals with steel shields to protect against contaminants.

2. Produk Langkungview

The Nice ER12 ball bearing is constructed from through-hardened ASTM International 52100 bearing quality steel, ensuring optimum wear resistance. Its design incorporates a nylon cage that evenly spaces the balls, contributing to reduced friction, vibration, and noise during operation.

fitur konci ngawengku:

• Single-row radial ball bearing for medium radial loads and speeds up to 5000 RPM.
• Extended inner ring with set screws for enhanced shaft support, eliminating the need for location spacers.
• Nylon cage for reduced friction, vibration, and noise.
• Through-hardened 52100 bearing quality steel for superior wear resistance.
• Synthetic rubber seals with steel shields on both sides, riding in a labyrinth groove to retain lubricant and exclude contaminants.

4. Setup jeung Instalasi

Proper installation is crucial for the longevity and performance of the bearing. Always ensure a clean working environment to prevent contamination.

1. Persiapan: Clean the shaft and housing thoroughly. Ensure there are no burrs, rust, or foreign particles.
2. Shaft Fit: The ER12 bearing features an extended inner ring with set screws. Slide the bearing onto the shaft. The fit should be snug but not excessively tight.
3. Ngamankeun: Once positioned, tighten the set screws on the extended inner ring to secure the bearing firmly to the shaft. Ensure even tightening to prevent misalignment.
4. Alignment: Verify that the bearing is properly aligned with the housing and shaft to prevent premature wear and excessive loads.
5. Lubrication: This bearing is pre-lubricated and double-sealed at the factory. No initial lubrication is required.

Caution: Never use excessive force during installation, as this can damage the bearing components, especially the seals and raceways.

5. Pitunjuk Operasi

The Nice ER12 bearing is designed for specific operating conditions. Adhering to these guidelines will maximize its lifespan and efficiency.

• Laju: The bearing is rated for speeds up to 5000 RPM. Exceeding this limit can lead to overheating and premature failure.
• Beban: It is designed to support medium radial loads. Avoid applying excessive axial or shock loads beyond its design capacity.
• Suhu: Operate within the recommended temperature range for the bearing's lubricant. Extreme temperatures can degrade the lubricant and bearing material.
• Lingkungan: While double-sealed, prolonged exposure to highly abrasive dust, corrosive chemicals, or excessive moisture should be minimized.

6. Pangropéa

Regular maintenance ensures the continued reliable operation of your ER12 bearing.

• Lubrication: The ER12 bearing is double-sealed and pre-lubricated for life under normal operating conditions. Re-lubrication ports are not present, and opening the seals is not recommended as it can compromise their integrity and introduce contaminants.
• Pamariksaan: Periodically inspect the bearing for signs of wear, damage, or unusual noise/vibration. Check the integrity of the seals for any cracks or leaks.
• beberesih: Keep the area around the bearing clean to prevent accumulation of dirt and debris that could potentially compromise the seals.
• Panyimpenan: If storing spare bearings, keep them in their original packaging in a cool, dry, and clean environment to prevent corrosion and damage.
