1.Product Specification:
Linear bearings are bearing elements for translation type motion. As in the case of rotary bearings, a distinction is drawn as to whether the forces occurring are transmitted by means of rolling or sliding elements. Each linear design has particular characteristics that make it especially suitable for particular bearing arrangements.
1. Enable high precision linear motion on round shafts
2. Sustain heavy loads with low noise and high stiffness
3. Perform under almost any environmental conditions and load capacities to satisfy a wide range applications
KH3050PP Linear Bearing – Precision Motion Control for Industrial Excellence
Elevate your machinery’s performance with the KH3050PP Linear Bearing, a robust and versatile component engineered for seamless linear motion in demanding applications. Designed to deliver reliability under heavy loads, this bearing combines advanced materials and precision manufacturing to meet the rigorous demands of modern automation.
Key Specifications
The KH3050PP Linear Bearing features an inner diameter of 30mm, an outer diameter of 50mm, and a length of 80mm, ensuring compatibility with standard linear shaft systems. Built from hardened carbon steel with a chrome-plated surface (HRC 58-62), it offers exceptional wear resistance and durability. With a dynamic load capacity of 8.2 kN and a static load capacity of 15.6 kN, the KH3050PP excels in high-stress environments. Its dual rubber seals (IP54-rated) protect against dust and contaminants, while pre-lubricated high-temperature grease ensures smooth operation with minimal maintenance.
Ideal Applications
The KH3050PP Linear Bearing is tailored for industries requiring precision and reliability:
- CNC Machinery: Ensures accurate motion control in milling, cutting, and engraving systems.
- Automated Production Lines: Supports high-speed robotics and conveyor systems in automotive or electronics assembly.
- Packaging Equipment: Handles repetitive heavy-load cycles in bottling and sealing machinery.
- Medical and Laboratory Systems: Compatible with sterilization processes in imaging devices or automated lab equipment.
- 3D Printing: Delivers low-friction linear motion for precision additive manufacturing.

Advantages of the KH3050PP Linear Bearing
- Superior Load Capacity: Engineered to withstand up to 15.6 kN static loads, making it ideal for heavy-duty operations.
- Corrosion Resistance: Chrome-plated surface ensures long-term performance in humid or chemically aggressive environments.
- Low Maintenance: Self-lubricating design reduces downtime, even in continuous 24/7 operations.
- Quiet Operation: Optimized for noise reduction (<45 dB at 1 m/s), perfect for noise-sensitive facilities.
- Industry-Standard Compatibility: Works seamlessly with SBR30 shafts and other common linear motion components.
Limitations to Consider
- Lubrication Requirements: High-speed applications (above 2 m/s) may require periodic re-greasing.
- Temperature Constraints: Not recommended for extreme environments exceeding -20°C to +120°C.
- Specialized Use Cases: Unsuitable for ultra-high vacuum or cryogenic systems without custom modifications.
Why the KH3050PP Stands Out
The KH3050PP Linear Bearing outperforms generic alternatives with its 20,000+ hour operational lifespan and 15% higher static load capacity than comparable 30mm bearings. Its precision-ground raceways and hardened steel construction minimize friction, ensuring consistent accuracy even after years of service.
Upgrade to the KH3050PP Linear Bearing and transform your equipment’s efficiency, durability, and precision. Ideal for CNC, automation, and industrial systems, this bearing is your gateway to frictionless performance.
