Manual Analog Dial Reading
Manual Analog Rockwell Hardness Tester Cast Iron Frame Dial Reading for Bearing Steel Testing
Type: Manual Rockwell · Initial Test Force: 10kgf (98.07N)
Product overview
The 500RA is a manual Rockwell hardness tester built on an integrated cast iron frame that resists deformation and displacement. It uses a weight-loaded structure for stable performance and high measuring accuracy, with readings taken directly from the analog dial at 0.5HR resolution. A precision hydraulic buffer provides smooth, adjustable loading speed. The machine covers nine Rockwell scales from HRA to HRK for quenched, tempered and annealed steel, castings, aluminum alloy, copper and bearing steel, and its accuracy conforms to GB/T230.2 and ASTM E18.
