Dünnwandige Vierpunkt-Kugellager
Thin section four-point contact ball bearings features
Lightweight Structure: Thin-section design reduces overall weight and saves installation space.
High Load-bearing Capacity: It can withstand radial, axial, and moment loads simultaneously, and can replace multiple conventional bearings.Withstands complex loads and is suitable for complex working conditions.
High Precision and Stability: Low friction, smooth operation, and low noise, making it suitable for high-speed or precision applications.
Flexible Application: Suitable for equipment requiring lightweight, compactness, and durability,such as small robotic arms, medical devices.
Thin Section Bearing Sealing Structure Design
The thin-walled design imposes extremely strict spatial constraints on the sealing components; therefore, the seals are ultra-thin structures, typically with a thickness of ≤1mm, and are divided into non-contact and contact types. Non-contact seals consist of a thin rubber lip and a metal frame, with no contact with the inner ring, resulting in low friction and suitability for high-speed applications. Contact seals use nitrile rubber (NBR) or fluororubber (FKM) for the sealing lip, which makes light contact with the inner ring, providing better dust and water resistance and suitability for harsh operating conditions.
Four-point contact ball bearings advantages
1. Compact Structure and Flexible Installation
Der single-row ball design makes the bearing lightweight, compact, and easy to install. LTZC uses a standard mounting hole distribution and can customize flange structures, gear types, and sealing methods according to customer needs, designing unique bearing solutions.
2. High Rotational Accuracy and Smooth Operation
Through LTZC's precision bearing machining technology (including CNC gear grinding, CNC hardening, and integral raceway machining), the four-point contact ball bearing achieves small clearance and good rotational rigidity, maintaining stable operating accuracy even under medium- and high-speed rotation conditions.
3. LTZC's High-Standard Heat Treatment and Material Guarantee Lifespan
LTZC uses high-grade bearing steels such as 42CrMo/50Mn and employs integral hardening + multi-point temperature-controlled induction hardening technology to ensure uniform raceway hardness and high wear resistance. This gives the four-point contact ball slewing bearing a long lifespan and high reliability.
4. Customizable Gear Structure
LTZC's gear machining capabilities cover modules from 4 to 30, ensuring gear surface hardness and transmission accuracy, making it particularly suitable for engineering machinery, vehicles, and lifting equipment. Get a quote for LTZC bearings
5. Fully Sealed Design for Harsh Conditions
LTZC uses double-lip rubber seals or metal labyrinth seals to enhance dust, mud, and sea fog resistance, and offers pressurized lubrication and high-temperature grease options, adapting to extreme environments.
6. Superior Balance of Cost and Performance
Compared toKreuzrollenlager, four-point contact ball bearings are less expensive and easier to maintain, yet still meet most load and accuracy requirements, making them the most economical and stable choice for medium-sized equipment.
