Roller Bearings

FAG roller bearings are a series of high-quality bearing products produced by the famous German bearing brand FAG, which are widely used in various industrial fields. FAG roller bearings mainly include tapered roller bearings, spherical roller bearings and drum roller bearings.

Tapered roller bearings

FAG tapered roller bearings are a type of separable bearings with tapered raceways on both the inner and outer rings. This type of bearing is divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. It is particularly suitable for occasions with large axial loads.

Spherical roller bearings

FAG spherical roller bearings (double row) are suitable for heavy-duty applications. They have two rows of symmetrical barrel rollers and can compensate for angular deviations of up to 0.5°, and can even compensate for angular deviations of 2° under low loads. This type of bearing is particularly suitable for situations where centering errors need to be compensated, such as heavy machinery and vibrating equipment.

Drum roller bearings

FAG drum roller bearings are single-row, self-aligning roller bearings that consist of a solid outer ring with a spherical raceway, a solid inner ring with two ribs and a cylindrical or tapered hole, and a drum roller with a cage. This type of bearing is suitable for bearing large radial loads and small axial loads, and is particularly suitable for situations where centering errors need to be compensated and impact radial loads need to be borne.

FAG Roller Bearings, a hallmark of precision engineering from the Schaeffler Group, are designed to deliver unmatched performance, durability, and reliability in the most demanding industrial and automotive applications. Renowned for their German engineering excellence, FAG roller bearings excel in managing high radial and axial loads, extreme temperatures, and harsh operating conditions. With a diverse portfolio including cylindrical, tapered, spherical, and needle roller bearings, FAG provides tailored solutions for industries ranging from aerospace and energy to heavy machinery and transportation. These bearings are synonymous with longevity, reduced maintenance costs, and optimized operational efficiency.

Key Features & Benefits

  1. High Load Capacity & Durability

Cylindrical Roller Bearings: Engineered to handle radial loads up to 3,500 kN, ideal for gearboxes, pumps, and electric motors.

Tapered Roller Bearings: Manage combined radial and axial loads (up to 50% of radial capacity) in automotive wheel hubs and heavy-duty transmissions.

Spherical Roller Bearings: Self-aligning design compensates for ±2.5° misalignment, perfect for vibrating screens and mining equipment.

Needle Roller Bearings: Compact design supports high radial loads in confined spaces, such as planetary gear sets and camshafts.

  1. Advanced Material Technology

Ultra-Clean Steel: Vacuum-degassed SAE 52100 chromium steel with controlled impurities enhances fatigue life by 40%.

Specialty Alloys: Stainless steel (AISI 440C) and hybrid ceramic (Si3N4) options for corrosive, high-temperature, or electrically insulated environments.

Surface Treatments: Durotect® coatings (e.g., phosphate, X-life) reduce friction and wear in contaminated conditions.

  1. Precision Engineering

ISO/ABEC Tolerance Classes: Precision-ground components meet ABEC-3 (ISO P6) to ABEC-7 (ISO P2) standards for applications like machine tool spindles.

Optimized Roller Profiles: Logarithmic roller contours in tapered bearings minimize edge stresses, extending service life.

  1. Sealing & Lubrication Innovations

Integrated Seals: Triple-lip seals (IP67) or labyrinth designs exclude dust, water, and debris.

Lubrication Flexibility: Pre-greased with FAG Arcanol® high-performance grease or compatible with oil circulation systems.

  1. Temperature & Environmental Resilience

Operating Range: -40°C to +200°C (standard); +250°C with high-temperature lubricants.

Corrosion Resistance: Stainless steel variants for marine, chemical, and food-grade applications (FDA/EC1935 compliant).

FAG Roller Bearings represent the pinnacle of engineering innovation, offering robust solutions for industries where reliability and performance are non-negotiable. Their advanced designs, material science, and commitment to sustainability ensure optimal operation in extreme conditions—from the high-speed demands of aerospace to the corrosive environments of marine applications. Backed by Schaeffler’s global technical support and a legacy of precision, FAG Roller Bearings minimize downtime, reduce energy consumption, and deliver long-term cost savings. For engineers and industries seeking uncompromising quality, FAG stands as the benchmark in roller bearing technology.

Spherical Roller Bearings
‌FAG Spherical Roller Bearings have large load capacity and self-aligning ability, suitable for low-speed or medium-speed applications, especially under heavy loads or impact loads. ‌ FAG Spherical Roller Bearings are divided into several types, including R, RR, RH, RHR and RHA, which differ in internal structure. Each type can be equipped with a cylindrical bore or a tapered bore, where the tapered bore bearings can be easily installed and removed through an adapter assembly or a pull-out sleeve. ‌ Application scenarios

Tapered Roller Bearings
‌FAG Tapered Roller Bearings ‌ are a type of bearing with high load capacity and a wide range of speeds. They are typically used to carry radial and unidirectional axial loads, and due to their design features, they are able to perform well in high load and high speed environments.
View
Cylindrical Roller Bearings
‌FAG Cylindrical Roller Bearings are bearings with high radial load capacity and low friction coefficient, suitable for heavy loads and high speed conditions. ‌ The main features of FAG cylindrical roller bearings include: ‌High radial load capacity‌: Suitable for heavy loads and shock loads. ‌Low friction coefficient‌: Reduces friction and is suitable for high-speed rotation. ‌Structural features‌: The inner and outer rings are separable for easy installation and removal. Bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings, and their designs and applications vary depending on the number of roller rows.

Axial-Tapered Roller Bearings
‌FAG Axial-Tapered Roller Bearings ‌are a special type of bearings that are primarily designed to withstand radial and axial loads acting simultaneously. The design features of this bearing include the fact that the projection lines of its raceways converge at one point (apex) on the bearing axis, thereby achieving true rolling action and reducing friction torque during operation.
View
Barrel Roller Bearings
FAG Barrel Roller Bearings ‌is a special cylindrical roller bearing with a drum-shaped roller, which is usually used to bear large radial loads and compensate for centering errors. This bearing consists of a solid outer ring with a spherical raceway, a solid inner ring with two ribs and a cylindrical or tapered hole, and a drum roller with a cage.

Needle Roller Bearings
‌FAG Needle Roller Bearings ‌are bearings with thin and long rollers, whose roller diameter is usually less than or equal to 5 mm, and whose length to diameter ratio (L/D) is greater than 2.5, with a compact radial structure and high load-bearing capacity.
