About Extended Inner Ring Bearings

Extended Inner Ring Bearings

Miniature bearings with extended inner ring for shaft sizes inch & mm

These stainless steel miniature bearings with extended inner ring have an inner ring that is wider than the outer ring by 0.0312" (0.0156" on each side. These bearings are easier to mount with the wider inner ring eliminating the need for spacers or washers.

Some sizes may be available in SAE52100 chrome steel but these are more usually supplied in AISI440C or KS440 (ACD34/X65Cr13) stainless steel. These extended inner ring miniature bearings can withstand heavy radial loads and moderate thrust loads in both directions.

Precision and Durability

Our extended inner ring bearings are crafted from high-quality chrome steel, ensuring excellent wear resistance and longevity. The P6 precision rating and metal retainer provide superior operational accuracy, making them ideal for demanding industrial applications like textile and agricultural machinery.

Versatile Applications

These single-row deep groove bearings are used extensively in textile machinery, agricultural equipment, and conveyors. Thanks to their robust load ratings, double-sealed design, and high limiting speed of 8000 rpm, they maintain optimal performance in varied operating conditions.

Easy Installation and Maintenance

With options for set screw or eccentric collar mounting, the installation process is straightforward and reliable. Grease lubrication and double sealing simplify upkeep, ensuring consistent operation and extended bearing life even in challenging environments.

FAQs of Extended Inner Ring Bearings:

Q: How are extended inner ring bearings installed in machinery?

A: Extended inner ring bearings can be mounted securely using either a set screw or an eccentric collar, making installation straightforward for textile machines, conveyors, or agricultural equipment.

Q: What are the key benefits of using these bearings in textile and agricultural machinery?

A: The deep groove structure and polished chrome steel finish deliver high load capacities, corrosion resistance, and durability, ensuring smooth and reliable performance even in challenging environments.

Q: When is it necessary to replace the bearings?

A: Bearings should be replaced at regular intervals or whenever signs of excessive noise, vibration, or decreased performance arise, especially if used near their operational limits of dynamic or static loads.

Q: Where are these extended inner ring bearings commonly used?

A: They are predominantly utilized in textile machinery, agricultural equipment, and conveyor systems due to their robust load ratings, precise engineering, and compatibility with standard industrial mounting methods.

Q: What is the lubrication process for these bearings?

A: These bearings are pre-lubricated with high-quality grease and feature double seals, minimizing the need for frequent relubrication and protecting against contaminants.

Q: How does the bearings corrosion resistance benefit its performance?

A: Corrosion resistance extends the service life of the bearing, keeps it running smoothly under adverse conditions, and reduces maintenance downtime, which is crucial for industrial applications.
