Series 40 Ball Bearing Orbit Block - Cheek

Features:

  • Low friction 2-stage Orbital ball bearing system
  • Highest working load in its class
  • Low profile and compact
  • High performance cleating
  • Base suits curved mounting surface

Lightweight

Kilogram for kilogram of working load, BB and RT Orbit Blocks™ are the world’s lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimizes the mass of the inactive return race and hub.

Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.

Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.

Highest Working Load In It's Class

The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.

The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modeled to be stress optimized.

Snackageddon: 40 Bags of Crunchy Chaos (and I Regret Nothing)
Flavor Name: Fun Times Mix, Size: 40 Count (Pack of 1)
As a self-proclaimed snack tactician and veteran of many a vending machine war, I approached the Frito-Lay Fun Times Mix Variety Pack with the skepticism of a man who’s been burned by stale pretzels and betrayed by underfilled chip bags. But this? This was a crunchy revelation. I bought this 40-pack for what I told myself was “emergency rations” during a long week of remote work. In reality, it became a full-blown snack safari. Each bag is a portal to a different salty universe—whether you're in the mood for the tangy rebellion of Doritos or the humble, dependable crunch of Lay’s Classic, this box delivers like a snack-themed Netflix binge. Pros: Variety that slaps: You get a solid mix—Doritos Nacho Cheese, Cheetos, Lay’s, Fritos, and more. No filler flavors that make you question your life choices. Portion control-ish: Each bag is just enough to satisfy a craving without triggering existential guilt. Perfect for bribery: Kids, coworkers, spouses—everyone has a favorite, and you now hold the power. Freshness: Every bag was crisp, sealed tight, and tasted like it came straight from the snack gods’ pantry. Value for money: At roughly 50 cents a bag, it beats the pants off gas station prices. Cons: Disappears mysteriously: I swear I only had three bags and now the box is empty. Either I blacked out in a snack frenzy or my family staged a coordinated chip heist. Uneven distribution: You might get 8 bags of Fritos and only 2 of the Cool Ranch Doritos. It’s a snack democracy, but some flavors are clearly more equal than others. Final Verdict: If you’re looking for a snack pack that brings joy, nostalgia, and a mild sense of shame when you realize you’ve eaten six bags in one sitting, this is it. Whether you're stocking a breakroom, prepping for a road trip, or just trying to survive another Monday, the Frito-Lay Fun Times Mix is your crunchy co-pilot. Would I buy it again? Already did. Twice. And I’m not even sorry.

Perfect for a Big Family – Kids Loved It!
Flavor Name: Fun Times Mix, Size: 40 Count (Pack of 1)
We got this Frito-Lay Fun Times Mix Variety Pack for our 7 kids, and they absolutely loved it! The box is huge and has a great variety of chips, so there’s something for everyone. Perfect for snacks, lunchboxes, or family gatherings. The quality is just what you expect from Frito-Lay, and with 7 kids, it lasted a good while (not very long, honestly 😄). We would definitely buy this again—a fun and convenient way to keep all the kids happy!

Great for the office
Flavor Name: Fun Times Mix, Size: 40 Count (Pack of 1)
These were a great option for the office break room! At the time I got them, they were a great value and the selection is high quality name brand snacks with good taste. It’s nice to have all the different options in one box instead of having to buy multiple products.
