Double column design

1. Loading capacity: The double-row design enables the bearing to withstand greater radial and axial loads. Compared with single-row deep groove ball bearings, it has obvious advantages in load-bearing capacity.

2. Good rigidity: The double-row structure provides higher axial rigidity, which is very important for maintaining stability under high load and high-speed operation conditions.

Crown steel cage

1. Separating and positioning the balls: The design of the shaped steel cage helps to effectively separate and position the balls in the bearing, ensuring that they are evenly distributed and maintain the correct motion trajectory.

2. Excellent stability: The crown-shaped steel cage provides good stability and helps reduce the vibration and noise of the bearing when rotating at high speed.

Suitable for high-speed operation

1. Low friction and high speed: The design of the crown-shaped steel cage double-row deep groove ball bearing reduces friction, allowing it to adapt to the requirements of high-speed operation and provide more effective performance.

Wide range of application fields

1. Industrial multi-field applications: Due to its high load-bearing capacity and adaptability, this bearing is widely used in manufacturing, heavy machinery, metallurgy, mining and other fields that require reliable load-bearing.

Adjustable gap

1. Adjustable inner and outer rings: The design of some crown-shaped steel cage double-row deep groove ball bearings allows users to adjust the clearance between the inner and outer rings of the bearing to adapt to different working conditions.

Long life and low maintenance cost

1. Wear-resistant material selection: Bearing parts are made of high-quality, wear-resistant materials, which increases the service life of the bearings.

2. Low maintenance requirements: Under appropriate conditions, shaped steel cage double row deep groove ball bearings generally require lower maintenance costs, reducing downtime and repair costs.
