Slewing Bearing For Excavator By Xuzhou D&r Engineering Machinery Co. Ltd.

Xuzhou D&R Engineering Machinery Co. Ltd. is mainly engaged in design and produce machinery products.The main products are slewing bearings gears. A A All the blanks for our slewing bearings are performed by hardening and tempering hardness can reach HB220-280 the strength is much higher than national standard of GB/T 3077 and GB/T 699 raceway using medium frequency induction hardening machine hardness can reach HRC55-62 the depth is bigger than 5 mm inner steel balls are treated by steel ball crushing test to ensure the load of the core. A A Our slewing bearings have many advantages: compact structure light weight low noise smooth operation high precision safe and reliable it can bear the axial force radial force and overturning moment it doing good on bearing heavy load and low speed. A A There are nine (9) different sizes available for slewing drives from 3" to 25" with more than 60 models to meet both regular and precise tracking requirements in PV CPV and solar thermal power tracking fields. We can survey design and produce all kinds of non-standard spur gear gears helical gears and bevel gears according to customers special requirements. Advanced production equipment and complete testing equipment to ensure the reliable quality high performance reasonable price short production time. A A We are committed to building brand by the quality reputation to win the development.
