SJA screw jacks manufacturers Shelf Abstract: SJA spiral screw lifter (SJA screw jack) is widely used in machinery, construction, water conservancy, metallurgical equipment, and other industries, with lifting, fall and by means of propulsion accessories, flip and height adjustment many functions. Model: SJA5 SJA10 SJA20 SJA50 SJA80 SJA100 SJA200 SJA300 SJB5 SJB10 SJB20 SJB50 SJB80 SJB100 SJB200 SJB300 SJA worm screw lifter (SJA screw jacks) is a basic crane parts, with a compact, small size, light weight, wide power source , easy installation, no noise, multi-function, supporting forms and more flexible, high reliability, long life and many other advantages. SJA screw lifter (SJA screw jack) Features thrust range: 0.5 to 30 tons - trip up to 8m, have to consider the stability of the screw and guide mechanism - duty of 30%, if the load factor is small, you can appropriately increase working system - Lifting speed of less than 1500mm / min (23mm / s), special circumstances can reach 46mm / s - less than 33 percent efficiency, self-locking function, large reduction ratio L1 absolute self-locking - precision positioning, additional anti-backlash means precision up to 0.05mm - absolute synchronization, the same motor can drive multiple screw jacks, mechanical synchronization - can be equipped with an encoder, limit switches, dust cover, safety nut, gear, general motors, servo motors, stainless steel, etc. - simple operation and maintenance, low noise? unique rectangular recess lift housing, increase the cooling capacity of the housing extend grease service life. Ductile iron casing material selection, a substantial increase in strength and performance of the housing, and is widely used in high temperature / low temperature. Use a square tail cover design, control screw does not rotate. Advanced processing equipment and processing and assembly technology, high product quality assurance, advanced design concepts to create a strong shock resistance, high strength, low noise, long life, small size and high quality products. Modular combination enriched product portfolio changes, screw jack directly with the motor / reducer any combination motor / Special Features attachments, integrated design, providing customers with thousands of easy options. In accordance with customer requirements non-standard design, such as stainless steel housing and Screw Jacks, long screw, low temperature, high temperature, and other products. SJA screw jacks Features: plunger speed: up to 75mm / s; input speed: 1800rpm; stroke range: up to 6.5 m; Standard Products accuracy to 0.1mm, including anti-backlash accessory accuracy to 0.04mm, absolutely high mechanical synchronization accuracy, smooth running, strong impact, can provide double screw, three screw, ball screw jacks. 10 minutes duty of 30%.
