Reali-Slim Thin Section Bearings
Reali-Slim thin section bearings are SKF’s premier inch-series thin section bearings, renowned for their versatility, precision, and availability in a wide range of sizes (from 50 mm to over 1 m bore). The range includes the TT series turntable bearings, BB series metric thin section ball bearings, and KT series tapered roller bearings. They are manufactured from high-grade steel with optional corrosion-resistant coatings or stainless steel. The Reali-Slim line offers multiple contact configurations (angular, radial, four-point) to handle radial, axial, and moment loads with minimal weight. These bearings are the standard choice for wafer handling robots, industrial robotics, defence radar pedestals, and precision rotary stages. With a comprehensive stock programme and custom engineering support, Reali-Slim bearings help designers push the limits of machine compactness.

Reali-Slim TT Turntable Bearings for Precision Rotary Tables
The TT series is a single four-point contact ball bearing with internal or external gear teeth, designed for precision turntable applications. It supports axial, radial, and moment loads in a single, thin package, ideal for indexing tables, pick-and-place systems, and medical device assembly stations.
KT Series Tapered Roller Thin Section Bearings
KT series combines the high load capacity and stiffness of tapered rollers with a thin cross-section. These bearings suit robotic arm joints where high moment loads must be supported without adding bulk, enabling lighter, faster robot designs.
