SBD□-G

Product Classification:

Product Details

Application

Braking of high-speed shaft system of wind turbine generator set.

Main feature

Normally closed design, compact appearance, hydraulic release, spring braking.

The opening limit switch and lining wear limit switch can be set for interlocking protection and fault display (when using PLC control).

Small setback and fast response speed; Few moving parts, high reliability, and simple maintenance.

Replacing the gasket does not require disassembling the brake, making it quick and convenient. “

Equipped with an oil drain to prevent hydraulic oil leakage from contaminating the brake disc, making it safer and more reliable.

Additional devices

Powder metallurgy lining

Semi metallic (asbestos free) liner

Opening limit switch

Pad wear limit switch

Automatic compensation device for pad wear

Retreat equalization device

Operating conditions

Ambient temperature:-40~+80℃

Relative humidity:≤95%

Special requirements can be discussed in order.
