Product Overview

 

The 608RS deep groove ball bearing is engineered for compact mechanical systems requiring stable rotational performance and reliable operation within limited installation spaces. Featuring standard dimensions of an 8 mm bore, 22 mm outside diameter, and 7 mm width, this single-row bearing provides a standardized solution for various industrial and consumer applications.
The design incorporates a double rubber sealed structure that protects internal components from external particles while retaining internal lubricant. Precision-machined raceways and an optimized deep groove geometry support smooth rotation and balanced radial load handling under continuous working conditions.

 

Product Features

 

Double Rubber Sealed Structure: Utilizes contact rubber seals on both sides to enhance lubricant retention and protect against dust intrusion, supporting consistent operational reliability.
Deep Groove Raceway Design: Features optimized internal geometry to accommodate radial loads effectively while maintaining low friction and smooth movement.
Compact Standard Dimensions: Engineered to precise 8x22x7 mm dimensions for seamless integration into small equipment and straightforward replacement processes.
Stable Rotational Performance: Utilizes precision-ground raceways and matched rolling elements to minimize vibration and ensure consistent performance during operation.

FAQ

 

Q: What is the difference between 608RS and 608ZZ bearings?

A: The 608RS utilizes rubber contact seals on both sides for superior protection against dust and moisture while retaining internal grease effectively, whereas 608ZZ features non-contact metal shields designed primarily for higher speed limits with lower frictional resistance.

Q: Can these bearings be customized for non-standard applications?

A: Yes, customizations include alternative stainless steel or ceramic materials, specialized internal clearances, custom seal designs, and unique dimensions based on provided engineering drawings or sample specifications.

Q: What is the standard material used in production?

A: The standard material is high-grade chrome steel AISI52100, chosen for its excellent wear resistance, high load-bearing capacity, and consistent fatigue life in general industrial environments.
