Product Classification

R+W metal bellows coupling BK1

Metal bellows coupling with flange connection

15-10000 Newton meters

Construction:

Each wheel hub has 6 or 8 metric threads

The centering of additional components can be easily achieved through internal or external coordination

Other accessory diameters and hole circles can be provided upon request

Temperature range: -30 to+100 ° C

Backclearance: Due to the use of pressure fit screw connections and verified principles, there is absolutely no backlash.

Service life: If the technical metal bellows coupling is durable and maintenance free.

Material

Bellows made of high elasticity stainless steel

Wheel hub material: steel

Short term overload: Allow 1.5 times the value.

Technical Specifications:

Rated torque: 15-10000 Nm

The speed can reach up to 10000 rpm.

>10000 revolutions per minute. Fine balanced design

Special solution for metal bellows coupling: Like other accessories, special materials and bellows can be achieved in a short period of time.

Characteristics of BK1 type metal bellows coupling:

Specific special solutions for customers

R+W metal bellows coupling BK2

BK2 metal bellows coupling and clamping hub

characteristic

Construction:

Each side is equipped with clamping wheels and an ISO 4762 screw

Starting from the 800 series, two are connected using non positive pressure pliers, with each offset of 180 °

Temperature range: -30 to+100 ° C

Backgap: Due to the use of a press in fixture connection and verified principles, there is absolutely no back gap

Service life: If the technical metal bellows coupling is durable and maintenance free

Coordination clearance: hub connection 0.01-0.05 mm

Material

Bellows made of high elasticity stainless steel

Additional materials are listed in the table
