Due to the deep integration of modern simplification, miniaturization, lightweighting, and compactness concepts into the design of rotating equipment, REALI-SLIM meets the needs of customers in this regard ® The bearing is designed as a fully hardened, thin section anti friction bearing. The medium and thin-walled bearings solve the size/weight problems of traditional bearings, shafts, and bearing seats, greatly reducing the design weight of the equipment.
The REALI-SLIM series thin-walled bearings of Zhongzheng Company are not only suitable for ordinary environments, but also for harsh and corrosive environments. We can provide dimensions of bearing inner diameter from 1 "to 40" or 20 mm to 360 mm, and cross-sectional area from 3/16 "to 1". thin-walled bearings are available in both imperial and metric sizes. The REALI-SLIM series offers open, sealed, and stainless steel bearings, while the ULTRA-SLIM series offers ultra lightweight thin-walled bearings.
1. Design features
Equal cross-section design: The cross-sectional height of the bearing is consistent throughout the circumference to ensure uniform force.
Ultra-thin construction: The overall thickness of the bearing is very small, making it suitable for installation in equipment where space is limited.
High precision: High-precision machining technology is usually used to ensure smooth operation and low friction.
Lightweight: Due to the small amount of material used, the overall weight is light, making it suitable for weight-sensitive applications.
2. Fields of application
Precision instruments: such as optical equipment, measuring instruments, etc.
Robot: Used on joints to reduce space occupation.
Medical equipment: such as CT machine, MRI machine, etc.
Aerospace: For high-precision, lightweight components.
Electronics: such as hard disk drives, micro motors, etc.
3. Material selection
Bearing steel: GCr15 and other high-carbon chromium bearing steels are commonly used, which have high hardness and wear resistance.
Ceramic materials: for use in high-speed, corrosion-resistant or high-temperature environments.
Stainless steel: for use in wet or corrosive environments.
4. Manufacturing process
Precision machining: CNC machine tools, grinding machines and other high-precision equipment are used.
Heat treatment: improve hardness and wear resistance through quenching, tempering and other processes.
Surface treatment: such as chrome plating, nitriding, etc., to enhance corrosion resistance and wear resistance.
5. Precautions for selection
Load capacity: Select the appropriate bearing type according to the actual load.
Speed requirements: High speed applications require the selection of appropriate lubrication methods and materials.
Installation space: Make sure the bearing size matches the installation space.
Environmental conditions: Consider factors such as temperature, humidity, corrosiveness, etc.
6. Frequently Asked Questions
Insufficient lubrication: This may lead to bearing wear or seizure, and the lubrication status needs to be checked regularly.
Improper installation: It may cause deformation or damage to the bearing, and it should be installed in strict accordance with the specifications.
Material fatigue: Long-term high-load operation may lead to material fatigue, which needs to be checked and replaced regularly.
