🚀Features & Advantages

Simple and Versatile: The basic structure consists of an inner ring, an outer ring, a set of steel balls, and a cage. It is the most commonly used type of rolling bearing, suitable for a variety of mechanical applications.

High-Speed Performance: Features a small friction coefficient and a high-speed limit, making it ideal for high-speed or extremely high-speed operations.

Low Maintenance: Bearings equipped with dust caps or seals on both sides are maintenance-free and lubricated for life.

🛠️Maintenance & Selection

Sealed Bearings: Require no additional lubrication during use. Operating temperature should be maintained between -30°C and +120°C.

Open-Type Bearings: Regular inspection and lubrication are required. Ensure the environment is clean to prevent dust and impurities from affecting performance.

Selection Advice: When choosing your bearing, consider load capacity, speed requirements, installation space, and precision requirements. Always verify that the equipment fits the 60mm x 130mm x 31mm dimension profile.

Frequently Asked Questions

What are the primary applications for these bearings?
These are widely used in industrial machinery, textile equipment, and various medical apparatus due to their versatility and load-bearing capacity.
What is the difference between open and sealed bearings?
Sealed bearings are maintenance-free and protected from contamination, while open bearings allow for customization and require regular lubrication checks.
Can these bearings handle high axial loads?
While excellent for radial loads, for significant axial loads, we recommend considering bearings with larger radial clearance or specialized designs.
What materials are the cages made of?
Cage materials vary, including brass, steel, and nylon, depending on your specific operating requirements and customization preferences.
What is the recommended operating temperature range?
For sealed variants, the recommended operating temperature is generally between -30°C and +120°C.
Do you offer OEM services?
Yes, we offer OEM services to meet specific customer requirements regarding dimensions, cage types, and precision grades.
