Ball Sleeve D=20/28X30 for Homag Woodworking Machine Tools

Product advantages and features

1.Compact design: The radial section height is extremely small, with an inner diameter of 20mm, an outer diameter of 28mm, and a thickness of 30mm. The structure is compact and suitable for applications with limited radial space, such as machines in the food and packaging industries.

2. Excellent sealing performance: Some models (such as KH20-PP) are equipped with double-lip seals, which can effectively prevent dust, impurities, etc. from entering the bearing interior, protect the bearing from contamination, and extend the service life of the bearing.

3.Easy to maintain: It has a re-lubrication function and can be re-lubricated through the grooves on the ball circulation channel, ensuring that the bearing remains in a good lubrication state during long-term operation and reducing maintenance workload and costs.

4.Long service life: Made of high-quality materials and advanced manufacturing techniques, the metal outer surface of the bearing is equipped with a plastic cage. Coupled with a well-designed seal and lubrication system, it can withstand certain loads and has a long service life. It can operate stably within a temperature range of -30 °C to + 80°C.

5.High precision: As a linear bearing of the INA brand, it features high manufacturing precision, ensuring the accuracy and stability of linear motion. It is suitable for equipment with high requirements for motion precision, such as precision testing equipment and precision measuring instruments.

6.High cost performance: INA KH20 linear bearings not only offer reliable performance and high quality but also have a good price-performance ratio, providing users with cost-effective linear motion solutions.

Product Technical Parameters

Product application scope

1. Food and packaging industry: Machines in this industry usually have limited space. INA KH20 linear bearings have a small radial section height, which can adapt to this space limitation. At the same time, its good sealing performance can prevent dust, impurities, etc. from entering the bearing interior, avoiding contamination of food or packaging materials and ensuring product quality.

2. Printing industry: Printing equipment such as screen printing machines requires high-precision linear motion to ensure the accuracy and consistency of printing. The high-precision positioning function of INA KH20 linear bearings can meet this demand and ensure the clarity and accuracy of the printed patterns.

3. Refrigeration equipment: Refrigeration compressors and other equipment require stable linear motion during operation. The long service life and excellent wear resistance of INA KH20 linear bearings enable them to work stably for a long time in refrigeration equipment. Meanwhile, their re-lubrication function also reduces maintenance workload and ensures the normal operation of the equipment.

4. Machine tool processing: In processing equipment such as milling machines and imported machine tools, INA KH20 linear bearings can provide precise linear motion for components such as the machine tool's worktable and tool rest, withstand certain cutting forces and torques, and ensure processing accuracy and surface quality.

5. Wind power generation: Some components of wind turbines need to perform linear motion during operation. The high load-bearing capacity and good stability of INA KH20 linear bearings can meet the working requirements of wind power generation equipment and ensure the reliable operation of the equipment.

6. Medical Devices: Some precision medical devices, such as precision testing equipment and precision measuring instruments, have extremely high requirements for the accuracy of linear motion. The high-precision characteristics of INA KH20 linear bearings enable them to be applied in the field of medical devices, providing a guarantee for the precise .
