Thin section bearings, also referred to as thin wall bearings,represent a specialized category of bearings renowned for their exceptional performance in applications where space and weight considerations are critical. With their thin cross-sections and compact dimensions, these bearings have proven to be ideal solutions for installations with limited available space. In this comprehensive article, we will delve into the world of thin section bearings, exploring their various types, unique characteristics, and diverse applications across a range of industries.
Types of Thin Section Bearings：
The covers of primarily come in three distinct types: ZZ, 2RS, and OPEN.
Each type is designed to cater to specific environmental and sealing requirements.
OPEN:OPEN type features unshielded bearings, offering maximum accessibility but without protective seals.
ZZ:The ZZ designation indicates shielded bearings, providing protection against contamination and debris ingress.
2RS:The 2RS denotes bearings fitted with rubber seals on both sides, ensuring enhanced sealing against moisture and other contaminants.
Characteristics of thin section bearings：
Thin section bearing sexhibit distinct characteristics that set them apart from conventional deep groove ball bearings.Notably, each series of thin section bearings is designed with a fixed cross-section size that does not increase proportionally as the inner diameter expands. This design feature ensures consistency in performance and dimensional stability across various sizes.One of the key attributes of thin section bearings lies in their use of small outer diameter steel balls, which significantly reduces friction. This results in enhanced rigidity and superior rotational accuracy, making them ideal for applications demanding precision and efficiency.
