Timken SAF Housed Unit Catalog

Product catalog summary
Overview
Timken offers a variety of housed units designed to improve productivity and uptime in various industries. These include ball bearing housed units, tapered roller bearing Type E housed units, spherical roller bearing solid-block housed units, SAF split-block housed units, and SNT plummer blocks. These units are engineered to endure harsh environments and are available in different materials and configurations to meet diverse industrial needs.
Introduction
Timken housed units are designed for easy installation and offer flexible options, including wide-inner-ring ball bearings for additional shaft support and various locking options. They are available in materials such as cast iron and steel, with multiple sealing options to protect against contaminants.
Ball Bearing Housed Units
These units are pre-assembled with bearings, housings, seals, and locking systems for easy installation. They are suitable for agricultural applications, fans, blowers, food processing devices, and conveyors.
Type E Housed Units
Featuring double-lip seals and locking collars, these units protect against contaminants and are suitable for industries like pulp and paper, power generation, and mining. They offer longer bearing life due to advanced technology and optimized bearing profiles.
Spherical Roller Bearing Solid-Block Housed Units
Made of solid steel, these units provide strength and durability in harsh conditions. They offer multiple locking configurations and sealing options, making them suitable for metals mills, aggregate and cement, and other heavy industries.
SAF Split-Block Housed Units
Available in cast iron, ductile iron, or cast steel, these units are designed for heavy loads and ease of installation. They are used in power generation, mining, and other industrial applications.
SNT Plummer Blocks
These blocks are available in metric sizes and are designed for heavy loads. They offer various sealing options and are used in industries like power generation, mining, and food processing.
Shelf Life and Storage
Timken provides guidelines for the shelf life and storage of grease-lubricated bearings and components. Proper storage is crucial to maintain product integrity, and deviations from recommended practices may reduce shelf life.
Specifications and Guidelines
The document provides detailed specifications and guidelines for selecting and fitting bearings, focusing on shaft tolerances and load applications. It includes tables for tolerance values and fitting practices for various bearing classes.
Load Applications
Load applications are categorized into normal, heavy, and very heavy loads, with appropriate bearing classes and clearances specified for each type. Recommendations are provided for specific applications such as electrical motors, turbines, pumps, and traction motors.
Fitting Practices
Guidelines emphasize the importance of selecting the correct shaft and housing fits based on operating conditions. Consulting with a Timken engineer is advised for more detailed information.
Lubrication Procedures
The document outlines lubrication systems for bearings, including oil bath, circulating systems, and oil-mist lubrication. Proper lubrication minimizes friction, transfers heat, and protects against corrosion.
Oil and Grease Advantages
A comparison table highlights the benefits of oil and grease lubrication. Oil is preferred for high-speed and high-temperature applications, while grease simplifies seal design and requires less frequent lubrication.
Viscosity Considerations
The selection of oil viscosity depends on factors like load, speed, and temperature. The document includes a comparison of ISO/ASTM and SAE viscosity grades.
Safety Warnings
Proper maintenance and handling practices are critical to avoid injury. Following installation instructions and maintaining proper lubrication is emphasized.
Grease Lubrication for Bearings
Proper grease lubrication is crucial for bearing performance. Excess grease can lead to churning, increasing torque and causing lubricant breakdown. Regular relubrication is essential, with intervals depending on operating temperature and sealing efficiency.
Grease Application Methods
Grease should be packed between rolling elements, with additional grease applied externally. Mechanical grease packers are recommended for frequent regreasing.
General-Purpose Industrial Grease
Polyurea and lithium-based greases are preferred for general-purpose lubrication, especially in moist environments. Greases should be smooth, homogeneous, and contain inhibitors for protection against oxidation and corrosion.
Grease Properties and Compatibility
Greases should not contain corrosive or abrasive materials and should have excellent mechanical and chemical stability.
Application Considerations
For high-speed applications, lighter base oil viscosity is recommended, while heavier viscosity is suitable for low-speed applications.
Spherical Roller Bearings
Timken spherical roller bearings are designed for high radial loads and consistent performance under challenging conditions.
Technical Catalog for SAF Split-Block Housed Units
The document provides detailed specifications, load ratings, and mounting data for spherical roller bearings across various series.
Specifications
Each bearing part number is listed with dimensions, dynamic and static load ratings, cage type, and mounting data.
Load Ratings
The catalog specifies dynamic and static load ratings, indicating the maximum load the bearings can handle under different conditions.
Mounting Data
Information on maximum shaft or housing fillet radius, backing diameter, and equivalent radial load factors is provided.
Thermal Speed Ratings
The catalog lists thermal speed ratings for oil and grease lubrication, indicating the maximum operational speeds for each bearing type.
Recommendations
Bearings are available with a tapered bore for adapter-type mounting, and users are advised to consult Timken engineers for the latest availability information.
Withdrawal Sleeves and Accessories
The document provides detailed specifications and assembly instructions for Timken's withdrawal sleeves and related accessories used in securing bearings to shafts.
Specifications
Withdrawal sleeves are designed with a push-type mounting arrangement and require a locking device such as a locknut or lockplate.
Components
The document outlines various components used in the assembly of bearings onto shafts, including locknuts, lockwashers, and lockplates.
Assembly Types
The document describes two main assembly types: SNW Assembly and SNP Assembly.
Recommendations
For large assemblies, the use of a hydraulic nut (HMV) is recommended to ease dismounting.
