Kamglide - Wear(Piston) ring, Bushes.
KAMGLIDE composites are advanced materials created by impregnating reinforcing fibers with thermosetting resins, resulting in superior properties compared to their individual components. These composites consist of a matrix that holds the reinforcement fibers together, distributing loads effectively. The fibers used include aramid, carbon, glass, and cotton, which provide primary load-bearing capabilities.
- Low Coefficient of Friction: Enables higher load and speed combinations.
- High Wear Resistance: Offers longer service life than bronze, with less impact from poor lubrication.
- Excellent Resilience: Absorbs high shock loads.
- High Load-Carrying Capacity: Due to high compressive strength from reinforcement orientation.
- Light Weight: Significantly lighter than steel, reducing energy consumption and system costs.
- Good Chemical Resistance: Suitable for harsh environments.
- Design Flexibility: Can be tailored for specific performance needs.
KAMGLIDE materials are used in various industries due to their advantageous properties. Applications include earth moving equipment, offshore and marine, hydraulics, agriculture, heavy transport, steel/aluminum manufacturing, automotive industry, paper/textiles production, and more.
KAMGLIDE offers various grades designed for specific conditions and applications, such as CN-10/CN-20 for hydraulic cylinders, CM-20 for dry environments, RS-20/RS-30 for marine and chemical plants, RS-40 for food processing, CS-10/CS-20 for fluid lubricated bearings, LS-30 for the textile industry, and LM-40 for high-temperature applications.
- Compressive strength varies across materials, with RS-40 offering a static strength of 290 MPa and dynamic strength of 80 MPa.
- Impact strength and hardness are specified, with RS-40 having an impact strength of 66 J/m2 and a Rockwell hardness of 100 HRM.
- Material swell in water is minimal, with RS-40 showing only 0.08% swell.
- Maximum working temperatures range from 120℃ to 200℃, depending on the material.
- Coefficient of linear thermal expansion is provided for both normal and parallel to laminate directions.
- Wear rings are designed to guide pistons and rods in hydraulic cylinders, preventing metal-to-metal contact and supporting horizontal loads.
- Standard cutting gaps and types of cuts for wear strips are specified, with bias and step cuts available.
- Calculations for wear ring width and cutting gaps are provided to ensure proper fit and function.
The document provides detailed information on various bearing materials, including M-20, RS-20/RS-30, CS-10/CS-20, and LM-40, used in applications requiring high wear resistance, chemical resistance, and mechanical strength.
- Running Clearance: Consider thermal expansion and moisture absorption when determining clearance.
- PV Limits: Important for bearing design, indicating the ability to handle frictional energy.
- Wall Thickness and Bore Closure: Allowance for bore contraction is necessary when pressing a bush into its housing.
- Environment Suitability: Selection of materials should consider environmental conditions, especially for composites containing graphite.
- Temperature and Load Limits: Detailed in tables for each material type, indicating maximum and minimum temperatures, sliding speeds, and load capacities.
- Frictional Coefficient: Varies by material and lubrication condition.
The document discusses the importance of the L/d ratio in bearing design, noting that a ratio higher than 2.0 can lead to stress concentrations and excessive localized heating. It suggests using two bearings with a small gap or increasing the inside diameter to mitigate these issues. The choice of mating metal surface is crucial, with harder materials preferred to ensure the bearing wears instead of the mating material. Recommended surface roughness values are provided to minimize wear.
For KAMGLIDE Bearing materials, stainless steel and hard chromium plated steel are recommended. Surface finish significantly affects wear, with ground surfaces preferred over turned surfaces. A fine polishing operation in the direction of bearing motion is beneficial.
The document emphasizes the user's responsibility to determine the suitability of Kamglide bearing materials for their intended use. It highlights that unknown factors can affect bearing performance, and users should conduct their own tests.
Soltri Corporation offers a limited warranty for six months from the date of sale, covering manufacturing defects. The company disclaims all other warranties and does not assume liability for advice or the performance of the product in specific applications. Users are advised to test the product's suitability for their needs.
Formulas for calculating bearing speed in rotation and oscillation are provided, along with definitions for variables such as radial load, bearing ID, and rotation speed.
