    ASTM D4693 Low Temperature Torque Tester For Grease Lubricated Wheel Bearings


    Low Temperature Torque Tester for Grease-Lubricated Wheel Bearings


    Introduction

    This Low Temperature Torque Tester is suitable for measuring the running performance of the grease in the specially manufactured, spring-loaded automobile wheel bearing assembly under low temperature conditions. The test principle is to fill the grease sample into a specially manufactured automobile wheel bearing assembly.The assembly is heated first, and then cold soaked at -40°C. In addition, other test temperatures can be set according to the requirements of the grease specifications. The spindle is rotated of 1r/min, and the torque value to prevent rotation of the hub is measured at 60 s.


    Characteristic

    ◆ Standard inboard and outboard tapered roller bearings, LM67010-LM67048 and LM11949

    ◆ Microcomputer temperature controller, temperature control range from normal temperature to -50℃

    ◆ Pt100 temperature sensor, high acquisition accuracy ±0.5℃

    ◆ This Low Temperature Torque Tester adopts imported compressor cascade refrigeration, low noise.

    ◆ The drive motor adopts a high-speed ratio of 1740/1, which can maintain a stable speed.

    ◆ The low temperature box is insulated with special materials, and there is no temperature influence from the outside.

    ◆ Digital display torque value.

    ◆ The loaded spring can withstand a pressure of 500N and is equipped with a pressure calibration device.

    ◆ Digital display of working hours and alarm.

    ◆ A set of standard grease loader is supplied with Low Temperature Torque Tester.
