HKL-1478 Low-Temperature Torque Tester
Overview
HKL-1478 Low-Temperature Torque Tester conforms to ASTM D1478 Standard Test Method for Low-Temperature Torque of Ball Bearing Grease. A ball bearing is packed completely full of the test grease and cleaned off flush with the sides. The bearing remains stationary while ambient temperature is lowered to the test temperature and held there for 2 h. At the end of this time, the inner ring of the ball bearing is rotated at 1 ± 0.05 r/min while the restraining force on the outer ring is measured. Torque is determined by multiplying the restraining force by the radius of the bearing housing. Both starting torque and torque after 60 min of rotation (running torque) are determined.
Features
This instrument adopts dual-compressor refrigeration, eliminating the need for circulating cooling water. It is using heat dissipation with a condenser which allows the cooling to start right after connecting the power.
The use of a Japanese Fuji digital temperature controller enables it to make very accurate adjustments. Besides, the Probes Pt100 temperature sensor is characterized by ultra sensitivity, ultra resolution, strongest anti-interference capacity, accurate control, and long working life.
The cryogenic chamber is equipped with top-notch sealing to keep the internal temperatures unchanged and stable during the tests. It doesn’t form any frost during the whole operation, either.
An internal fan will stop to assure the safety of the operator if, during the testing, the door safety switch that has been installed is opened.
Test results are displayed digitally in m n/m (millinewton meters).

FAQ
Q1: What standards does this product (HKL-1478 Low-Temperature Torque Tester) comply with?
A: HKL-1478 Low-Temperature Torque Tester conforms to ASTM D1478 Standard Test Method for Low-Temperature Torque of Ball Bearing Grease. A ball bearing is packed completely full of the test grease and cleaned off flush with the sides. The bearing remains stationary while ambient temperature is lowered to the test temperature and held there for 2 h. At the end of this time, the inner ring of the ball bearing is rotated at 1 ± 0.05 r/min while the restraining force on the outer ring is measured. Torque is determined by multiplying the restraining force by the radius of the bearing housing. Both starting torque and torque after 60 min of rotation (running torque) are determined.
Q2: What is the applicable scope of HKL-1478 Low-Temperature Torque Tester?
A: This test method covers the determination of the extent to which a grease retards the rotation of a slow-speed ball bearing by measuring starting and running torques at low temperatures (below -20°C). This test method was developed using greases having very low torque characteristics at -54°C. Specifications for greases of this type commonly require testing at this temperature. Specifications for greases of other types can require testing at temperatures from -75 to -20°C.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one unit, and delivery is approximately 20 days after advance payment.
Q4: Do you provide product operation manuals or technical documentation?
A:Yes. In order to help you achieve your goals, we are offering you a simple way to get to a wide range of resources such as product manuals, quick operation guides, application cases and standard operating procedures (SOPs). All you need to do is log in to the download center on our official website or contact our customer service team to get the documents you want.
Q5: Do you provide online training services?
A: If needed, we will provide online installation and debugging services, as well as comprehensive operation training. We also offer 24/7 online training support to end users throughout the year.
