LBT-QJA Rubber Bearing Aging and Creep Performance Test Chamber (Stainless Steel, Both Inside and Outside)

Anti‑aging performance and creep resistance are two critical long-term performance indicators for rubber bearings. The rubber bearing aging chamber is a testing device used to evaluate the anti‑aging properties of rubber bearings. In addition to conducting aging tests on polymeric materials (such as plastics and rubbers) and electrical insulating materials, this chamber can also be employed for the aging and drying of non‑volatile, non‑flammable, and non‑explosive substances. It serves as test‑and‑inspection equipment in industries such as aerospace, automotive, home appliances, and research, enabling high‑temperature aging tests on materials used in electrical and electronic products. The equipment complies with standards including “Plate Rubber Bearings for Highway Bridges” JT/T 4‑2019 (Appendix A), “Rubber Bearings — Part 4: Ordinary Rubber Bearings” GB/T 20688.4‑2007 (Appendix A), and GB/T 3512‑2014 “Vulcanized or Thermoplastic Rubber — Accelerated Aging in Hot Air and Heat Resistance Test.”

LBT-QJA Rubber Bearing Aging and Creep Performance Test Chamber (Stainless Steel, Both Inside and Outside)

Description

Product Introduction:

Anti‑aging performance and creep resistance are two critical long-term performance indicators for rubber bearings. The rubber bearing aging chamber is a testing device used to evaluate the anti‑aging properties of rubber bearings. In addition to conducting anti‑aging tests on polymeric materials (such as plastics and rubbers) and electrical insulating materials, this chamber can also be employed for aging and dry‑heat baking of non‑volatile, non‑flammable, and non‑explosive substances. It serves as test‑and‑inspection equipment in industries including aerospace, automotive, home appliances, and research, enabling high‑temperature aging tests on materials used in electrical and electronic products. The equipment complies with standards such as “Plate Rubber Bearings for Highway Bridges” JT/T 4‑2019 (Appendix A), “Rubber Bearings — Part 4: Ordinary Rubber Bearings” GB/T 20688.4‑2007 (Appendix A), and GB/T 3512‑2014 “Vulcanized or Thermoplastic Rubber — Accelerated Aging in Hot Air and Heat Resistance Test.”

Product Features:

·The rubber bearing aging chamber boasts excellent performance, an aesthetically pleasing appearance, and high reliability.

·The entire unit is crafted from high-quality SUS304 brushed stainless steel.

· The control system features a touch-screen interface, offering convenient and intuitive operation; the heating system employs PID control for precise temperature regulation with high accuracy.

·The insulation system employs ultra-fine glass fiber to fill the thermal‑insulation zone, and non‑metallic high‑temperature‑resistant materials are used at the junction between the inner and outer shells, effectively minimizing heat transfer outward. The cabinet door is sealed with a refined sealing compound that exhibits no aging or hardening even under high‑temperature conditions, ensuring excellent sealing performance.

·The air‑circulation system features a specially designed airflow path, employing low‑noise, long‑life, air‑conditioner‑type cooling fans; the fan impellers are predominantly blade‑type centrifugal fans, ensuring excellent temperature uniformity within the test chamber.

· Equipped with a large‑view, double‑layer tempered glass observation window;

·Equipped with safety protection devices: over-temperature protection and motor overload protection, ensuring the safe operation of the testing machine.
