Thin-section deep groove ball bearing|Thin Section Bearings|Precision Bearings|Products|NewBee Transmission

Description

Deep groove ball bearings achieve efficient load-bearing of radial loads and support bidirectional axial loads by having the balls make contact with the symmetrical arc-shaped raceways. Performance characteristics: Low friction: The precisely polished raceways match the balls,reducing energy loss. High-speed adaptability: The optimized contact angle and lubrication design support operation at tens of thousands of revolutions per minute. Long service life: The homogeneous materials and heat treatment process enhance the fatigue resistance strength. Customization options: Special lubricating greases (for high-temperature or low-temperature conditions),non-standard dimensions,and hybrid designs with ceramic balls are supported.

Features

Dominated by radial load

The single-row deep groove design maximizes the radial load-bearing efficiency.

Low noise and vibration

Precision manufacturing ensures smooth operation, making it suitable for precision instruments.

High rotational speed capability

The low-friction design is suitable for high-speed scenarios such as motors and spindles.

Bidirectional axial support

It can bear moderate bidirectional axial loads without the need for additional thrust bearings.

Working Principle

Contact between rolling elements and raceways: The balls roll within the deep grooves of the inner and outer rings, evenly distributing the radial force. Load capacity: Radial load: It is the main load direction, accounting for more than 80% of the designed load-bearing capacity. Axial load: It can bear bidirectional axial forces, with a maximum of approximately 20% of the radial rated load. Sealing and lubrication: Open type: Regular replenishment of lubricating grease is required. Sealed type: It has built-in lubricating grease and features a maintenance-free design.

FAQ

What are the differences between deep groove ball bearings and four-point contact bearings?

Deep groove ball bearings mainly bear radial loads, and their axial load capacity is limited; four-point contact bearings can simultaneously bear radial, axial and moment loads.

Why choose thin-section deep groove ball bearings?

The thin-section design saves space and is suitable for miniature devices (such as drone motors and miniature pumps).

How to choose the sealing type?

The open type is suitable for scenarios with regular maintenance; the sealed type is suitable for dusty or humid environments.

Does it support the design of hybrid ceramic balls?

Yes, it does. Ceramic balls can reduce weight and increase the rotational speed, but an additional customization period is required.
