Thin section bearings

SKF Thin Section Bearings are ultra-slim, high-precision bearings designed for applications where space and weight constraints are critical. These bearings feature a unique cross-section design that maintains high load capacity while minimizing radial space requirements. They are widely used in robotics, aerospace, medical equipment, semiconductor manufacturing, and other high-tech industries where compactness and precision are essential.

SKF Thin Section Bearings are specially designed bearings designed to meet high-precision, high demand application scenarios. Their main features include reducing weight, minimizing space occupation, lowering friction, enhancing design flexibility, and achieving excellent operational accuracy. SKF Thin Section Bearings typically adopt a design with large inner holes and small cross-sections, making the overall structure of the bearing more compact. It can significantly reduce the external dimensions of the equipment and lower production costs without affecting performance

application area

SKF Thin Section Bearings are widely used in multiple fields, including:

Aerospace: used for the manufacturing of high-precision equipment such as satellites and rockets

Robots: providing flexible and reliable support for the joints of robots

Medical system: ensuring the stable and accurate operation of medical equipment and the safety of patients

product type

SKF Thin Section Bearings offers a diverse range of product types, including:

Reali Slim series: Based on a single cross-sectional design, the cross-section remains constant as the inner diameter increases, greatly saving space and weight. This series includes TT turntable bearings, suitable for important applications that require precise positioning and lightweight design

BB series: Deep groove ball bearings, suitable for applications that require miniaturization and lightweighting, with ultra-thin bearing cross-sections and low friction, high-speed characteristics

KT series: tapered roller bearings, suitable for thin applications that require high load-bearing capacity and multiple advantages

Design Features

Ultra-Thin Cross-Section: Radial cross-section as low as 3.5% of the bore diameter

Four Standard Series:

K Series (Radial Contact): Standard deep groove design

C Series (Angular Contact): For combined radial and axial loads

X Series (Four-Point Contact): High moment load capacity

E Series (Extra Thin): Lightest possible design

Material Options:

Standard: High-carbon chromium steel (AISI 52100)
