The product is provided 'AS IS' and the viability of ATCC® products is warranted for 30 days from the date of shipment, provided that the customer has stored and handled the product according to the information included on the product information sheet, website, and Certificate of Analysis. For living cultures, ATCC lists the media formulation and reagents that have been found to be effective for the product. While other unspecified media and reagents may also produce satisfactory results, a change in the ATCC and/or depositor-recommended protocols may affect the recovery, growth, and/or function of the product. If an alternative medium formulation or reagent is used, the ATCC warranty for viability is no longer valid.  Except as expressly set forth herein, no other warranties of any kind are provided, express or implied, including, but not limited to, any implied warranties of merchantability, fitness for a particular purpose, manufacture according to cGMP standards, typicality, safety, accuracy, and/or noninfringement.

The speed ratings establish the highest rotational speed at which a bearing can function without generating excessive heat or experiencing premature wear.

The size of a ball bearing is determined by the shaft size and the specific requirements of the application, which has a significant impact on its performance and capabilities. Consequently, different industries utilize various sizes of ball bearings to meet their specific needs.

While ATCC uses reasonable efforts to include accurate and up-to-date information on this product sheet, ATCC makes no warranties or representations as to its accuracy. Citations from scientific literature and patents are provided for informational purposes only. ATCC does not warrant that such information has been confirmed to be accurate or complete and the customer bears the sole responsibility of confirming the accuracy and completeness of any such information.

The size chart includes crucial measurements, including the inner diameter (bore diameter), outer diameter, and width of the bearing. These dimensions are crucial in establishing whether the bearing is compatible with the intended shaft and housing.

Here, we will explore the importance of the ball bearing size chart and learn how to interpret and utilize it effectively. In addition, charts as follows provide commonly used ball bearing sizes and dimensions to help select the exact ball bearing for specific applications, in turn, enabling the equipment to realize optimal performance, reliability, and longevity.

After prolonged use, it’s not unusual for the bearing identification number to become illegible or worn out. In such cases, manual measurement of the bearing becomes necessary. Accurate measurements can be obtained using a vernier caliper. In the absence of a vernier caliper, measurements can still be taken carefully using a ruler.

Please see the material transfer agreement (MTA) for further details regarding the use of this product. The MTA is available at www.atcc.org.

To make the proper selection for your application, it is crucial to have a clear understanding of the bearing size chart.

This article presented ball bearing size charts that are commonly used. In addition, it offers guidance on how to define, interpret, and measure ball bearings.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

The ball bearing size chart offers a comprehensive reference guide to a wide range of dimensions and specifications for ball bearings.

Ball bearings come in various sizes based on the shaft size and the requirements of the application. Due to their usage in different industries, they are needed for a wide range of applications, from oil drills to skateboard wheels. How are these bearing sizes determined? How can we understand the ball bearing size chart?

In general, ball bearings are smaller, load capacities are weaker. In such cases, small ball bearings are better suited for applications where space efficiency is prioritized over overload capacity. Precision miniature bearings are frequently used in incredibly small applications, including robotics, medical instruments, and semiconductor equipment. Conversely, larger bearings are designed to handle heavier loads, making them ideal for industries such as agriculture, mining, drilling, and heavy power tools. Some manufacturers such as Runsom Precision even offer custom bearing sizes tailored to the unique requirements of specific applications.

The series number of a bearing can be found directly on the bearing and corresponds to a specific combination of measurements. To determine the measurements of a particular bearing, ball bearing size charts are readily accessible. The commonly used series are 6200 and 6300, which typically encompass sizes ranging from 10 x 30 x 9 mm (.394 x 1.181 x .354 in) to 150 x 320 x 65 mm (5.906 x 12.598 x 2.559 in).

A ball bearing is a type of rolling bearing in which a ball is placed between the inner and outer rings that reduces rotational friction and supports radial and axial loads. Also, it improves the efficiency of mechanical power transmission and is commonly used in light industrial machinery. A basic ball bearing comprises four components: a ball, an inner ring, an outer ring, and a cage or retainer. The balls and rings are typically made of high chromium steel.

Ball bearings allow for smooth and efficient rotational motion and minimum friction and wear in various machinery and mechanical systems. They consist of ball rollers positioned between the inner and outer steel rings to withstand larger loads.

Ball bearings endure both radial and axial loads during operation. Load ratings listed in the size chart represent the maximum capacity a bearing can withstand without encountering premature failure.

When considering bearing performance, take into account clearance and tolerance. These factors can significantly influence the functionality of the overall system, so it’s vital to ensure that they’re appropriate for your applications.

To find the correct bearing match or replacement, it is essential to consider other significant aspects of the bearing number. Pay attention to the suffix, which provides additional details about the bearing design and features:

If shipping to the U.S. state of Hawaii, you must provide either an import permit or documentation stating that an import permit is not required. We cannot ship this item until we receive this documentation. Contact the Hawaii Department of Agriculture (HDOA), Plant Industry Division, Plant Quarantine Branch to determine if an import permit is required.

If a requested product is not a hazardous chemical, or does not contain any hazardous chemicals, a SDS is not required and therefore will not be provided.

Ensure that the dimensions of the bearings align with the specific requirements of your shaft and housing. Confirm that the bore diameter, outer diameter, and width correspond to the specifications of your machinery.

Ball bearings are essential components used in a multitude of machinery and mechanical systems, allowing for smooth and efficient rotational motion and minimum friction and wear. These devices comprise an outer and inner ring with a set of balls in between.

When measuring bearings, their inner diameter, outer diameter, and width are taken into account. The size of a bearing is typically indicated as ID x OD x W and is usually expressed in millimeters but can be converted to inches. Actually, most manufacturers and suppliers provide bearing measurements in both imperial and metric units.

The internal gap between the balls and raceways of a bearing is known as bearing clearance. This clearance affects the axial and radial play of the bearing and also influences its thermal expansion characteristics.

The bearing size and attributes are identified using a standardized numbering code system developed by ABMA. However, at Runsom Precision, we can manufacture non-standard bearings with unique characteristics through our custom CNC machining services.
