Catalog Usage
The catalog provides dimensions, tolerances, load ratings, and engineering sections to assist in selecting the appropriate Timken housed units. It includes guidelines for shelf life and storage of grease-lubricated bearings and components.
Shelf Life and Storage Guidelines
Timken provides guidelines for the storage of grease-lubricated bearings, emphasizing proper storage conditions to maximize product life. Key points include maintaining storage temperatures between 0°C and 40°C, keeping relative humidity below 60%, and ensuring the area is free from contaminants and vibrations.
Handling and Maintenance Warnings
Proper maintenance and handling are crucial to prevent equipment failure. Excessive force should not be used during mounting or dismounting, and components should not be heated with an open flame. Bearings should not operate above 121°C.
Product Features and Benefits
Timken's Type E housed units offer enhanced performance with a 113% increase in calculated life and 25% more load capacity compared to standard bearings. They feature corrosion-resistant housing and double-lip seals for improved grease retention.
Engineering and Bearing Life Calculations
The engineering section provides guidance on selecting Type E housed units, considering factors like speed, load, and environmental conditions. Bearing life is statistically evaluated using the Weibull distribution function, with the L10 life representing the duration 90% of bearings will last before fatigue.
Specifications and Selection Methods
  • Specifications: Outlines the use of double extended tapered roller bearings suitable for radial, thrust, or combined loading.
  • Selection Methods: Includes various methods for selecting bearings based on load conditions and application requirements, such as radial loads, combined radial and thrust loads, and thrust-only applications.
Load and Speed Rating Tables
Detailed tables provide load ratings, maximum speeds, and allowable radial loads for various shaft diameters and conditions.
Installation and Lubrication Guidelines
Proper installation is crucial for performance. The document emphasizes using clean, straight shafts and proper alignment. Lubrication is essential to maintain antifriction characteristics, with recommendations for relubrication intervals based on operating conditions.
Product Data Tables
Detailed tables provide specifications for various housed unit types, including dimensions, part numbers, and weight.
Recommendations
The catalog suggests using one collar for certain sizes and highlights the importance of correct spacing and alignment for optimal performance.
