High Precision Medical Grade Slewing Bearing

Product Overview

CT Machine Slewing Ring is a specialized high-precision slewing bearing exclusively designed for medical CT scanner gantry rotation systems. Different from standard industrial slewing bearings, this medical-grade slewing ring is engineered for ultra-smooth vibration-free rotation, micron-level positioning accuracy and low-noise operation, which directly determines CT imaging clarity and diagnostic accuracy. As the core rotary load-bearing component of CT scan equipment, it stably supports high-speed continuous gantry rotation, effectively eliminates image artifacts and blurring, and guarantees reliable long-term operation of medical imaging devices in hospital diagnostic environments.

Core Key Features

1. Medical-Grade Ultra-High Precision

Adopts single-row four-point contact ball structure optimized for medical equipment, achieving positioning precision within 4 microns. The optimized raceway grinding process ensures uniform stress distribution, enabling accurate repeatable rotary positioning. It effectively avoids imaging deviation caused by mechanical displacement, fully meeting strict medical imaging precision standards and delivering clear, distortion-free CT scan images for clinical diagnosis.

2. Zero Vibration & Ultra-Low Noise Operation

Precision matched rolling elements and custom flexible retainers eliminate rotational jitter and friction vibration. The whole set runs stably at high rotating speed with extremely low operating noise, creating a quiet and safe examination environment for patients. Constant stable rotation greatly shortens scanning time, improves hospital inspection efficiency and reduces patient waiting time.

3. Premium Alloy Material & Stable Durability

Forged from high-strength 42CrMo and 50Mn alloy steel with integral quenching and precise raceway hardening treatment. The material features high strength-to-weight ratio, excellent fatigue resistance and structural stability, resisting long-term high-frequency cyclic operation fatigue. It maintains consistent precision and structural stability during long-term continuous medical operation, avoiding precision attenuation and equipment failure.

4. Dust-Proof & Clean Medical Sealing Design

Equipped with multi-layer dedicated medical sealing structure, effectively blocking fine dust, tiny particles and air contaminants from entering the bearing interior. The fully sealed design prevents internal lubricant leakage, keeps the internal structure clean, and complies with hospital clean room and medical equipment hygiene requirements. It requires minimal routine maintenance and reduces equipment downtime.

5. Lightweight Integrated Structure & Easy Installation

Compact integrated structural design saves internal space of CT gantry while ensuring strong composite load capacity, capable of bearing axial load, radial load and overturning torque simultaneously. Standard reserved mounting holes enable quick and accurate installation and replacement, perfectly matching mainstream CT scanner models.
