Three row roller type slewing bearing, slewing ring used on EAF(electric arc furnace)

Hereunder are the structures of slewing bearings which we can produce:

1. slewing ring bearing production process

Forging – Normalizing & Tempering – Rough Machined – Quenching & Tempering – Semi Finished Machined – Case Hardening – Grinding & Finish Machining – Assembly – Packing & Delivery

2. slewing ring bearing installation feature

Before installation, checking the installation of host, supporting materails have sufficient strength, the juncted surface should be machinery processing, and the surface is flat. Under special requirements, you can compensate some plastic materials.

3. slewing ring bearing main application

It combines the upper and lower togrther, and supports the weight of upper and the machine workload, making the upper rotates along with the lower or adverse. It is used widely in construction machinery and all kinds of equipment platform. For example, port equipment, metallurgical equipment, drilling platform.

Applications:

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 core.

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.
