Series 40 Orbit RT Sheave Replacement Cassette

The Series 40 ball-bearing Orbit Blocks™ provides the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fiber reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks - the perfect balance of performance and reliability.

As well as traditional single swivel blocks, the range includes single and double sheave lashing or soft attachment options through to multiple sheave blocks including those with quad and quin sheaves. The range is highly versatile allowing a multitude of possible systems right up to a 12:1 purchase mainsheet system for off-the-beach performance catamarans.

Series 40 Orbit Blocks™ are fitted with our carbon-reinforced C-Cleat™ for secure rope holding with low entry and exit efforts, and fairleads for fast action from any angle. Cleat arms are made from stainless steel and adjustable for setting your preferred cleating angle.

Ball Bearing versions incorporate our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.

High Load versions are designed specifically for any application where high dynamic or static loads are expected. They feature a high-strength grade 2205 stainless steel sheave & hub together with a triple bearing race to maintain low friction at very high loads. 

Features:

  • Class-leading dynamic and static load ratings, highest in their class
  • Lightweight, yet strong. Toughened, glass fiber reinforced nylon replaces stainless steel straps used in our traditional utility blocks
  • Low friction 2-stage ball bearing system for efficient and effortless trimming
  • Soft attachment, lashing, and traditional swivel shackle head options
  • Low profile and compact
  • High performance cleating

Applications:

  • Mainsheet systems and spinnaker sheets on dinghies, OTB catamarans and sportsboats to 8m (26ft)
  • Halyard, vang and backstay applications on boats to 9m (30ft)
  • Control line applications on larger yachts

Great toy!!!
Style: Original
My dog went mental over this ball!!! She will let me roll it through the backyard or in the house and she will go nuts for it but the great part, she will play by herself with this ball. She will roll it and jump on it and just have a blast. Since this is not a normal chew toy, my dog's big, she only gets it when I'm with her. It kind of makes it our special thing when I pull it out. We play every day with it and her enthusiasm has never lessened. She can be in another room when I take it out of the cabinet and the second she hears it, she will run into walls in her rush to get to me so we can play! It really is better than just throwing a ball back and forth. She's completely engaged the entire time it's out. I highly recommend it but just know it's not a normal toy that you can just throw to your dog and walk away. It is an amazing toy to help you bond with your pet.

Great for dogs that need to stay busy
Style: Original
My dog absolutely loves this ball. It is a little noisy so we take it out in the yard and let her play with it there. I highly recommend it if you have a dog that get bored easily. This will surely keep them busy.

Fun for the Dogs and Kids
Style: Original
My dog seems to love this ball. Super sturdy for an aggressive chewer. Easy to play with. Makes the tube sound when it rolls which keeps the dogs attention well. Super fun. It’s made out of hard plastic so it’s not soft at all. Can take this anywhere.

A must have for active dogs
Size: Max Size, Size: Max Size
I normally do not write reviews unless a product is really good or really bad. I have a dog that thinks chasing balls is the only thing in life and unfortunately she has a mom that has anchor pins in both shoulders. We've been using this ball launcher for little over a year. It goes through about 32 dirty balls, 3 times a day and has held up amazingly. It is even full of dirt and still keeps on working, it looks like R2D2 went thru a battle. 😆 I recently bought a second one as a back up because I can't believe this poor thing hasn't given up yet. I rotate the balls because my dog brings them back wet and muddy, then they won't launch as far, so I knock some dirt off of a dry one and launch it. I would highly recommend this for active dogs.
