BS ISO 9628:2019

What is ISO 9628 - Insert bearings and eccentric locking collars about?   

ISO 9628 is an International Standard that discusses rolling bearings. 

ISO 9628 specifies the dimensional and geometrical characteristics, boundary dimensions and tolerances of insert bearings and eccentric locking collars, and the radial internal clearances of insert bearings. 

ISO 9628 is a machine element geometry standard as defined in the geometrical product specification (GPS) system presented in the matrix model of ISO 14638. 

Who is ISO 9628 - Insert bearings and eccentric locking collars for?  

ISO 9628 on rolling bearings is relevant to:  

• Manufacturers of rolling bearings  
• Manufacturers of insert bearings and eccentric locking collars 
• Manufacturers of applications such as gear boxes, wind turbines, electric motors etc 
• Mechanical engineers  

Why should you use ISO 9628 - Insert bearings and eccentric locking collars?   

Insert bearing is a radial rolling bearing with a spherical outside surface and an extended inner ring with a locking device. The locking device, used for fixing the inner ring to the shaft, may be an eccentric locking collar or set screws either in a concentric locking collar around the inner ring or directly in the inner ring. 

ISO 9628 provides guidance on characteristics, boundary dimensions, radial internal clearances, and tolerances. Adopting a standardized design framework can ensure that assembly components are aligned as per your specific engineering needs for overall efficient functioning. ISO 9628 can provide uniformity and consistency to manufacturing processes by following these established criteria. If you are a manufacturer, you can impart excellent service despite rapid acceleration, temperature or load, assisting in improved performance across a wide range of the end-use applications. 

What’s changed since the last update?  

 BS ISO 9628:2019 supersedes BS ISO 9628:2006+A1:2011, which is withdrawn. BS ISO 9628:2019 includes some technical changes with respect to BS ISO 9628:2006+A1:2011. These include:  

• Diameter series 3 has been included 
• The fractional expression “1-1/6” for 28,575 mm has been corrected to “1-1/8” 
• Introduction of tolerance on D to get interchangeability among bearings from different manufactures 
• The geometrical product specification (GPS) system has been applied
