Introduction

Sealed Type Thin Section Four Point Contact Ball Bearings (Type X) can withstand three types of loads (radial load, axial load, and moment), so it can withstand greater stiffness. On the basis of the open type equal section four-point contact ball bearings, seals are installed for both sides. Standard type four point contact ball bearings with seals are contact seal bearings RS type (one side seal), 2RS type (two side seal) and non-contact seal bearings RZ type (one side seal), 2RZ type (two side seal).Sealed Type Thin Section Four Point Contact Ball Bearings (Type X) are more efficiently lubricated during use. Sealed Type Thin Section Four Point Contact Ball Bearings (Type X) have a better lubrication effect in the process of use, and also reduce the number of times of grease filling, and also play a role in dust prevention.

Sealed Type Thin Section Four Point Contact Ball Bearings, identified as Type X bearings with seals, represent a cutting-edge solution designed to accommodate both radial and axial loads while providing an additional layer of protection against environmental contaminants. These bearings combine the unique four-point contact design with sealing elements for enhanced performance in diverse applications.

Standard industrial seals are usually made of NBR, Sealed Type Thin Section Four Point Contact Ball Bearings (Type X) can also be supplied with customized seals such as Silicone Rubber, Vi materials, etc. for high temperatures and other extreme conditions that may be encountered.
