With clamping shaft sleeve

Specification: 15-10000nm

Easy to install

There are many length types

Low moment of inertia

DetailsParameterVideo

Structure:

With clamping collar and one side screw iso4762, starting from 800 series,

Every two 180 degrees of rotation is offset by the strong adhesive clamp connection, which is offset by the clamp connection

Temperature range: - 30 to + 100 ° C

Clearance: there is absolutely no back clearance through clamp connection with strong adhesion and established principles

Service life: according to the technical specifications, the metal bellows coupling can be durable and maintenance free

Fit clearance: shaft sleeve connection 0.01 - 0.05 mm

Material Science:

The bellows is made of high elastic stainless steel

See table for other materials

Short time overload: up to 1.5 times of TkN value

Technical parameters: up to 10000 rpm. When fine dynamic balance is used, it can exceed 10000 RPM (balance accuracy grade is g2.5)

Special solutions for metal bellows coupling: for example, other matching lengths, special materials, bellows and ATEX technical requirements can be made in a short time.

Features of BK2 metal bellows coupling:

Easy to install

Small installation space

Light weight and small moment of inertia
