FAG E1 Spherical Roller Bearings

Product catalog summary

Introduction
FAG E1 Spherical Roller Bearings are engineered to enhance cost-effectiveness and operational reliability through the X-life premium grade. This standard improves product quality and optimizes key parameters such as fitting, maintenance intervals, and lubricant selection.

Advantages of the E1 Design
The E1 design offers higher radial and axial load capacities, reduced bearing temperatures, and improved safety against ring fracture, leading to increased reliability and cost-effectiveness. It allows for downsizing, resulting in more compact and efficient bearings.

FAG E1 Spherical Roller Bearing Program
The program includes eight series with bore diameters from 20 mm to 320 mm. Narrow bearings are suited for high speeds, while wide bearings provide high load capacity. Special designs are available for challenging conditions like vibratory stresses.

Characteristics of E1 Spherical Roller Bearings
Designed for heavy-duty applications, these bearings feature two rows of symmetrical barrel rollers to compensate for shaft deflections and misalignment, meeting DIN 635-2 standards with higher load ratings due to longer rollers.

Basic Designs and Alignment
Most bearings up to 320 mm in diameter are of the E1 design, capable of compensating for misalignments up to 0.5° under normal conditions.

Tolerances and Bearing Clearance
FAG bearings are manufactured with normal radial bearing tolerances, with T41A specification bearings having narrow tolerances. They are available with normal clearance CN, or increased clearances C3 and C4.

Lubrication and Speed Suitability
FAG bearings feature a lubricating groove and holes for simplified lubrication, operating at temperatures up to 200 °C, with special considerations for polyamide cages.

Tapered Bore and Cages
Most series are available with a tapered bore, identified by suffix K or K30, and come with pressed steel, molded polyamide, or machined brass cages for different applications.

Load Capacities and Suffixes
The bearings support high thrust loads with specific suffixes indicating design features like tapered bores or special designs for vibratory stressing.

Applications
E1 spherical roller bearings are used in construction machines, gearboxes, mining machinery, conveyors, and ship propulsion systems.

Overview
FAG E1 spherical roller bearings are designed for high load capacity and reliability, suitable for applications like rudder engines, rolling mills, and hoisting equipment.

Specifications and Applications
Spherical roller bearings must meet different requirements based on their application, such as high static load capacity for rudder bearings and high speeds and temperatures for paper machines.

Accessories
FAG E1 spherical roller bearings are complemented by fastening elements, housings, and Arcanol rolling bearing greases, forming optimally matched assemblies.

Mounting, Maintenance, and Monitoring
Proper mounting, lubrication, sealing, and maintenance are crucial for maximizing bearing capacity. Monitoring is cost-effective where production loss is expensive.

Technical Data
Extensive tables detail dimensions, load ratings, and specifications of various FAG E1 spherical roller bearings, categorized by shaft diameter ranges.

Design Variations
Special designs for vibratory stress applications are mentioned, such as the 22330E1.T41A model, with tapered bore versions like 23236E1AK.M.

Dimensional Data
Tables provide dimensions for shaft and bearing sizes, including diameter, width, and radius, along with mass codes and specific bearing codes for identification.

Notes
The document emphasizes the accuracy of the information but disclaims liability for errors, reserving the right to make changes for technical progress.
