Available in cast iron, ductile iron, or cast steel, SAF units are designed for easy installation and maintenance, offering various sealing options for industries like power generation and mining.
SNT Plummer Blocks
SNT blocks are available in metric sizes, designed for heavy loads, and offer multiple sealing options for industries such as cement and food processing.
Shelf Life and Storage
Timken provides guidelines for the shelf life and storage of grease-lubricated bearings, emphasizing proper storage conditions to maintain product integrity.
Specifications and Procedures
The document provides technical specifications and guidelines for the installation, fitting, and maintenance of Timken SAF Split-Block Housed Units, focusing on spherical roller bearings. It includes tables with tolerance ranges and fitting practices, emphasizing proper installation to prevent damage and ensure optimal performance.
Mounting and Fitting
Spherical roller bearings can be mounted individually or with other bearings. The document describes using stabilizing rings in SAF housings to create fixed or floating bearings, with recommended fitting practices emphasizing interference fits to prevent wear and damage.
Installation Warnings
Proper maintenance and handling are critical to avoid injury or damage, with special care required for bearings used in explosive atmospheres.
Tapered Bore Designs
Tapered bore bearings simplify mounting and dismounting, with the use of adapter sleeves and the importance of achieving appropriate operating clearance.
Radial Internal Clearance
Guidelines for selecting radial internal clearance (RIC) based on operating conditions are provided, with tables for both cylindrical and tapered bore bearings.
Lubrication Systems
The document outlines various lubrication systems, including oil bath, circulating systems, and oil-mist lubrication, each suited for specific operational conditions.
Lubrication Types
Oil is preferred for high-speed or high-temperature applications, while grease simplifies seal design and requires less frequent lubrication.
Standards and Compliance
Timken lubricants comply with European REACH regulations, ensuring only registered products are sold within the EU.
Viscosity Considerations
The selection of oil viscosity is crucial, influenced by load, speed, and environmental factors, with a comparison of ISO/ASTM and SAE viscosity grades provided.
Grease Lubrication and Consistency
Grease consistency varies from semi-fluids to solid grades, measured by penetration number, with the NLGI classification system categorizing grease consistency.
Temperature Considerations for Greases
Greases must be selected based on performance at low and high temperatures, with synthetic greases offering advantages in wide temperature ranges.
Contamination and Grease Selection
Contamination from abrasive particles and water can significantly reduce bearing life, with greases offering high water resistance recommended for environments with water ingress.
Timken Application-Specific Lubricants
Timken offers a range of lubricants designed for specific applications, including high-temperature, anti-wear, and water-resistant additives.
Grease Lubrication for Bearings
The document discusses the importance of proper grease lubrication in bearing assemblies to prevent leakage and breakdown of lubricant properties.
Grease Application Methods
Grease is preferred over oil for ease of use in industrial applications, with bearings initially packed with grease requiring periodic relubrication.
General-Purpose Industrial Grease
Polyurea and lithium-based greases are recommended for general-purpose lubrication, especially in high moisture environments.
Application Considerations
For high-speed applications, lighter base oil viscosity greases are suggested, while heavier viscosity greases are recommended for low-speed applications.
Spherical Roller Bearings
Timken's spherical roller bearings are designed for high radial loads and consistent performance under challenging conditions.
Specifications
The catalog lists dimensions, load ratings, and other technical parameters for different bearing models, such as the 232 series.
Design and Construction
Timken's pillow blocks are designed for heavy-duty applications, featuring rugged cast-iron or steel housings.
Mounting Procedures
The document outlines mounting options for both tapered and straight bore bearings.
Lubrication and Seals
Timken pillow blocks are compatible with grease and oil-bath lubrication systems.
Recommendations
The catalog advises consulting Timken engineers for applications involving non-standard shaft sizes or extreme conditions.
Assembly Components
Each pillow block assembly includes a housing cap and base, cap bolts, bearing, bearing adapter, locknut and lockwasher, stabilizing ring, and triple-ring seals.
Ordering Instructions
The document specifies that for complete pillow block assemblies, the basic number is listed in the provided tables.
Additional Notes
The document includes notes on speed ratings, shaft diameter tolerances, and the use of stabilizing rings for fixed versus float mounting.
Withdrawal Sleeves and Accessories
The document provides detailed technical 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.
Tables and Data
The document includes extensive tables listing dimensions and specifications for various bearing numbers, shaft dimensions, and adapter dimensions.
Recommendations
For large assemblies, the use of a hydraulic nut (HMV) is recommended to ease dismounting.
Conclusion
The document serves as a comprehensive guide for selecting and assembling Timken's withdrawal sleeves and accessories, providing essential specifications and recommendations for optimal performance.
