Linear Bearings and Shafting

Product catalog summary
Overview: The document provides comprehensive technical information on PBC Linear's Round Shaft Technology, focusing on linear bearings and shafting. It covers linear ball bearings and Simplicity® plain bearings, detailing their engineering, performance, applications, and specifications.
Linear Ball Bearings: Designed for smooth, quiet operation with excellent rigidity, these bearings feature a surface texture that retains lubrication, minimizing metal-to-metal contact. They are available with a steel jacket or a self-aligning super bearing shell, offering low friction and consistent movement.
Simplicity® Plain Bearings: Utilizing the Frelon® break-in and transfer process for self-lubrication, these bearings offer maintenance-free operation across a wide temperature range (-400°F to +400°F) and provide vibration damping to eliminate fretting corrosion. Certified Simplicity 60 Plus Shafting is recommended for maximum performance.
Product Types and Materials: The document lists various product types, including plain, ball, thin wall, sleeve, and flange bearings, with materials ranging from aluminum alloy to stainless steel. It also covers pillow block and flange mount options, emphasizing ease of mounting and compact design.
Applications: Bearings are used in diverse applications such as thermoforming, lab equipment, additive manufacturing, printing, assembly stations, stone saws, heavy-duty cutters, and welding machines, valued for their self-lubricating properties and ability to operate in contaminated environments.
Performance Benefits: Plain bearings can handle up to 20 times the load of ball bearings and excel in contaminated environments, while ball bearings offer precise, low-friction performance but are more susceptible to contamination.
Frelon® Liner Materials: Made from PTFE and fillers, Frelon liners provide low wear, low friction, and self-lubrication. Different formulations cater to various shafting materials and applications.
Simplicity® 60 Plus® Shafting: Engineered for optimal bearing performance, this shafting holds lubrication and ensures the longest bearing life.
Technical Information: Includes details on running clearance, load ratings, and installation guidelines, emphasizing the importance of choosing the right bearing design for specific applications.
Running Clearance: Simplicity bearings offer Precision and Compensated classes, suitable for high precision and parallel shaft applications, respectively.
Bearing Shell and Materials: Available in aluminum alloy with an anodized finish or 316 stainless steel, offering good strength and corrosion resistance.
Self-Alignment Feature: Bearings come with a standard straight or crowned self-aligning O.D., allowing for misalignment capability.
Pillow Blocks: Made of aluminum alloy, these blocks are interchangeable with industry-standard ball bearing pillow blocks, offering built-in self-alignment.
Load Capacity and Performance: Simplicity bearings can carry 4 to 20 times the load of a linear ball bearing, absorbing shock loads and vibration.
Wear Rate and Life Expectancy: Life expectancy depends on factors like shaft hardness, surface finish, temperature, and lubrication.
Lubrication and Chemical Resistance: Recommended lubricants include Waylube Oil and light oils, with excellent chemical resistance offered by specific materials.
Temperature and Rotary Applications: Bearings operate effectively in temperatures ranging from -400°F to +400°F and perform well in rotary applications if properly applied.
Submerged Applications and Cleanrooms: Suitable for submerged conditions and cleanrooms due to low outgassing and minimal particulate buildup.
Lubrication System and Seals: A lubrication system with a felt wick and Zerk fitting is recommended for high-speed and high-load applications.
Specifications: Outlines materials and specifications for linear motion solutions, focusing on bearings and scrapers.
Bearing Alignment: Linear ball bearings can operate under misalignment but may damage shafting, whereas Simplicity bearings stop moving without damage.
Product Codes and Series: Provides detailed part numbers for various series with specifications for materials.
Ordering Information: Includes options for bearing I.D. features, housing I.D. features, and special modifications.
Performance Benefits: Highlights the high precision and rigidity of Simplicity® ball bearings.
Variety of Types: PBC offers a full line of ball bearings, emphasizing interchangeability and precision control.
Types of Bearings: Includes Closed Type, Clearance Adjustable Type, and Open Type, available in various sizes and standards.
Materials and Construction: Bearings feature a solid steel outer shell and an industrial-strength polymer ball retainer.
Pillow Blocks: Available in both open and closed configurations, offering self-alignment.
Flanged Bearings: Available in various series, providing excellent rigidity and smooth operation.
Performance Benefits: Bearings are size interchangeable with industry-standard ball bearings and PBC’s Simplicity® plain bearings.
Ordering Information: Retainer materials, flange types, and modifications are specified for different series.
Dimensional Information: Detailed specifications for various bearing sizes and configurations are provided.
Conclusion: PBC Linear offers a comprehensive range of linear ball bearings designed for various applications, ensuring high performance and adaptability to specific needs.

PBC LINEAR ® ROUND SHAFT TECHNOLOGY Plain Bearings & Ball Bearings Overview LINEAR PLAIN & BALL BEARINGS Good engineering principles dictate that the best bearing design be utilized for any given bearing application. Each type of bearing has advantages and disadvantages. Strengths or limitations can make it a clear choice depending on the application environment. At other times, an engineer will have a choice because multiple types of bearing can meet the need. In 1983, PBC Linear ® created the self-lubricating Simplicity ® linear bearing – a technology that solves problems in dirt, vibration,...
