● Frame: 50 x 100 x 2.5T x R8 rounded rectangular tube, swing arm: 60/50 x 3.0T round tube and 40 x 80 x 3.0T flat oval tube; link: 50 x 100 x 2.5T x R8 rounded rectangular tube; ballast box: 50 x 120 x 2.5T flat oval tube and R angle rectangular tube.

● The cushions are created using a polyurethane foaming technology and single PU forming technology to ensure the cushion never collapses. Based on an ergonomic design, the hardness is kept at 65°±5°to ensure a suitable hardness that is suitable for just about any body type. The surface of the cushion is a synthetic rubber that has undergone extensive testing in order to prevent peeling and fading.

● The seat has 5 different levels of adjustments at 100mm each. Users can easily adjust the seat simply by pulling and lifting the seat, then placing it at the desired height.

● The cam is made of high quality 8.0T hot rolled plate by laser cutting, while the guide rope groove is welded together for added durability.

● The balance weight is made of high quality steel material that has undergone a surface treatment process to prevent corrosion.

● The pedals are made of PVC and equipped with a built-in steel skeleton for added comfort.

● The moving guiding rail is made of 45# alloy steel at a diameter of 45mm. They are ground and formed in high temperatures, then chrome plated for a high wear and corrosion resistance.

● Protector: The protector is made through one time molding of ABS, then painted and sprayed for surface protection, and surrounded by imitation leather for added appearance attractiveness.

● Chain wheel: 100mm high-strength engineering plastic, precision machined bearing.

● PVC plastic grip

● Bearing: The bearing is from the top Chinese company of Renben, with an injection molding ABS plastic bearing cover.

● Injection molding ABS mid-decorative trim.

● The weight plates are made of 20# alloy steel, giving them a smooth surface with no pit or hemps, ideal thicknesses and varying weights. There are also damping cushions placed between the weight plates

● The guide bars use hollow stainless steel. They are made through a grinding and polishing process, and will not rust, even after extensive usage.

● Weight stack cover: one time molding ABS, 304 stainless steel magnetic cover, high-quality parts.

● The steel cable uses 6 x 19+1 standard. The outside diameter is 5.8mm and the diameter of the bare slope is 3.5mm. The maximum effective load bearing weight is 1,000kg, which can be stretched more than 100,000 times.

● The training picture is made of PVC and attached using 3M high viscosity glue to prevent it from wearing off after being exposed to dampness or corrosion.

● The foot pad is made of PVC using once injection molding technology.

● The scale is made of 2mm stainless steel with laser cutting and laser engraving technology.

● The material of the screws is A2-70 stainless steel, with other equipment parts equipped with 12.9 level alloy steel screws.
