D&R =Dependable and Responsible.
Xuzhou D&R Engineering Machinery Co., Ltd. is mainly engaged in design and produce machinery products.The main
products are slewing bearings.
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
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.
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.
We are committed to building brand by the quality, reputation to
win the development.
