Pfaff SB Sheave Block

Machined steel pulleys with sealed ball bearing fitted in a fabricated bracket assembly.

Guiding with DSRB S wire rope sheave blocks for BETA PROLINE and SILVERLINE electric rope winches. The dynamic all-rounder with variable rope and sheave diameters and cable deflections of up to 180° can move loads of up to 8 t with ease and absolute reliability.

Typical for Pfaff-silberblau is the high standard of quality: With a sheave block for manual and powered operation, equipped with grease-filled, sealed ball-bearings as standard.

A carefully coordinated system of application-specific cable diameters and matching turned precision cable groove ensures that the unit is also wear-free. The side plates are zinc plated on this range. The pulley is powder coated and the bearings are sealed and self-lubricated

*Other size options are available upon request.

Reference to M ø and M1 ø

These are long holes (elongated holes) e.g. 26/30 means;

Bore Ø 26 mm, designed as long hole with a length of 30 mm.

Why?: When mounting the pulleys, the position and feeding angle of the rope in the pulley respectively, can be fine-adjusted by a slight movement of the pulley within the long hole.
