DMM Gyro Pulley
Description
Description
The DMM Gyro is a swiveling pulley with roller bearings, providing high efficiency. Manufactured in Wales using hot forging technology and CNC machining – it shows in the details. Smoothly turned surfaces protect the rope, and the robust axle resists side forces better than thinner designs.
The series comes in three variants, and this is the Standard. Standard is a clean, efficient block without extra features — the right choice when you just need a reliable pulley.
Suitable for ropes up to 13 mm. The flared edges of the side plates reduce the bending radius and increase efficiency even when the rope runs at an angle. Compact design.
Features
- Roller bearings for high efficiency — reduce friction and make load handling easier
- Swing cheeks for easy rope insertion
- Hot-forged body reduces sharp edges and rope wear
- Large axle bore diameter provides increased resistance to side forces from the cheeks
- Prusik-minding side plates (PM and Twin) — prevent prusik from jamming in the block
- Load-bearing becket on Twin — increases possibilities for mechanical advantage systems
- Fairlead flares on cheek plates reduce bending radius and improve efficiency
